थर्मोकपल को समझना: एक व्यापक अवलोकन

तापमान माप के क्षेत्र में, थर्मोकपल वे महत्वपूर्ण उपकरण होते हैं जो बहुमुखी, टिकाऊ और व्यापक रूप से उपयोग किए जाने वाले सेंसर के रूप में सामने आते हैं। वे सीबेक प्रभाव के सिद्धांत पर कार्य करते हैं, जिसमें तापमान भिन्नता के जवाब में 2 अलगअलग धातुओं के जंक्शन द्वारा एक वोल्टेज उत्पन्न होता है। विभिन्न प्रकार के थर्मोकपल हैं, जिनमें से कुछ विशिष्ट तापमान सीमाओं के साथसाथ वातावरण के लिए भी उपयुक्त हैं।

थर्मोकपल के प्रकार

  • बीप्रकार के थर्मोकपल: बीप्रकार के थर्मोकपल का उपयोग अक्सर उच्च तापमान वाले वातावरण में किया जाता है। प्लैटिनमरोडियम मिश्र धातु (PtRh30-PtRh6) के साथ डिज़ाइन किए गए, ये बीप्रकार के थर्मोकपल 1700 डिग्री सेल्सियस तक मापने वाले अत्यधिक उच्च तापमान परिदृश्यों को पूरा करते हैं, जो उन्हें रासायनिक और अर्धचालक उद्योगों में अनुप्रयोगों के लिए उपयुक्त बनाते हैं। वे एयरोस्पेस, सेमीकंडक्टर विनिर्माण और कुछ प्रयोगशाला अनुप्रयोगों जैसे उद्योगों में भी उत्कृष्टता प्राप्त करते हैं।
  • आरप्रकार के थर्मोकपल: आरप्रकार के थर्मोकपल में प्लैटिनमरोडियम मिश्र धातु (PtRh13-Pt) होता है और यह 1600°C तक तापमान सहन कर सकता है। अपनी उच्च सटीकता और अच्छी स्थिरता के लिए जाने जाते हैं वे आमतौर पर प्रयोगशालाओं, औद्योगिक सेटिंग्स और रिफाइनिंग प्रक्रियाओं आदि में पाए जाते हैं। सटीकता के बावजूद, ये आरप्रकार के थर्मोकपल हजारों डिग्री से ऊपर के तापमान पर अत्यधिक प्रतिक्रियाशील हो जाते हैं और खराब हो सकते हैं। आसानी से दूषित हो सकते हैं। इसलिए, उनकी सटीकता और स्थिरता का कम तापमान वाली गतिविधियों जैसे सल्फर रिकवरी इकाइयों आदि में बेहतर उपयोग किया जाता है।
  • एसप्रकार के थर्मोकपल: आरप्रकार के थर्मोकपल के समान, ये एसप्रकार के थर्मोकपल प्लैटिनमरोडियम मिश्र धातु (PtRh10-Pt) का उपयोग करते हैं और उच्च तापमान का सामना करते हैं। इन्हें मुख्य रूप से 1600 डिग्री सेल्सियस तक मापने वाले उच्च तापमान अनुप्रयोगों में नियोजित किया जाता है। उनके अनुप्रयोगों में धातुकर्म, धातु शोधन सिरेमिक, चिकित्सा उद्योग और उच्च तापमान वाली रासायनिक प्रक्रियाएं शामिल हैं।
  • प्रकार के थर्मोकपल: क्रोमेल (90% निकल और 10% क्रोमियम) और कॉन्स्टेंटन (45% निकल और 55% तांबा) की विशेषता वाले, प्रकार के थर्मोकपल एक व्यापक तापमान रेंज (-270 डिग्री सेल्सियस से 1000 डिग्री सेल्सियस) को कवर करते हैं। ये बहुत लागत प्रभावी भी हैं. वे एचवीएसी सिस्टम, खाद्य प्रसंस्करण और प्रयोगशाला उपकरणों में उपयोग के लिए आदर्श हैं। इन प्रकार के थर्मोकपल में उच्च आउटपुट, तेज़ प्रतिक्रिया समय और गैरचुंबकत्व होता है। ये विशेषताएँ उन्हें क्रायोजेनिक्स, विमान और प्रवाह कक्षों आदि में उपयोग के लिए उपयुक्त बनाता है।
  • जेप्रकार के थर्मोकपल: लौह और कॉन्स्टेंटन मिश्र धातुओं से युक्त, जेप्रकार के थर्मोकपल एक मध्यम तापमान रेंज (-210 डिग्री सेल्सियस से 1200 डिग्री सेल्सियस) प्रदान करते हैं। उनकी लागतप्रभावशीलता और बहुमुखी प्रतिभा उन्हें विभिन्न औद्योगिक और घरेलू अनुप्रयोगों के लिए उपयुक्त बनाती है। इसलिए, उनकी सामर्थ्य और मध्यम तापमान सीमा के कारण इनका उपयोग आमतौर पर औद्योगिक अनुप्रयोगों और घरेलू उपकरणों में किया जाता है। इन जेप्रकारों का उपयोग आमतौर पर तारों पर बनने वाले संघनन के कारण परिवेश के तापमान के नीचे नहीं किया जाता है क्योंकि इससे लोहे में जंग लग जाती है। इसलिए, इनमें केप्रकार की तुलना में उच्च तापमान पर छोटी तापमान सीमा और कम जीवनकाल होता है।
  • एनप्रकार के थर्मोकपल: एनप्रकार के थर्मोकपल में निकलक्रोमियमसिलिकॉन और निकलसिलिकॉनमैग्नीशियम मिश्र धातु होते हैं। -270°C से 1300°C की तापमान सीमा के साथ, वे उच्च तापमान ऑक्सीकरण के लिए उत्कृष्ट प्रतिरोध प्रदान करते हैं। उच्च तापमान ऑक्सीकरण के प्रति उनके प्रतिरोध के कारण, वे अक्सर एयरोस्पेस और परमाणु उद्योगों में अपना अनुप्रयोग पाते हैं। केप्रकार की प्रतिद्वंद्वी सटीकता और कीमत बिंदु को देखते हुए, इन एनप्रकार को आरप्रकार और एसप्रकार के लिए बेहतर विकल्प माना जाता है।  
  • केप्रकार के थर्मोकपल: सबसे व्यापक रूप से उपयोग किए जाने वाले थर्मोकपल में से एक, केप्रकार के थर्मोकपल क्रोमेल और एलुमेल मिश्र धातुओं का उपयोग करते हैं। वे व्यापक तापमान रेंज (-270°C से 1372°C) को कवर करते हैं। वे अपनी विस्तृत तापमान सीमा और विश्वसनीयता के कारण उत्पादन, ऑटोमोटिव और एचवीएसी सिस्टम में उपयोग के लिए व्यापक रूप से उपयुक्त हैं। हालांकि ये सटीक हो सकते हैं, फिर भी 750 के आसपास और उससे ऊपर के तापमान के लिए उपयोग किए जाने पर इन्हें पुन: अंशांकन की आवश्यकता होती है। यदि संक्षारक प्रतिरोध प्राथमिक चिंता का विषय हो तो उत्कृष्ट धातु प्रकार वैकल्पिक होते हैं। ये विश्वसनीय, लागतकुशल और विस्तृत तापमान सीमा के साथ सटीक हैं।
  • टीप्रकार के थर्मोकपल: तांबे और कॉन्स्टेंटन मिश्र धातुओं से बने, टीप्रकार के थर्मोकपल -270 डिग्री सेल्सियस से 400 डिग्री सेल्सियस तक तापमान सीमा को कवर करते हैं। वे काफी स्थिर हैं और -59 से 370 (-75 से +700) के बीच सबसे अच्छा काम करते हैं, जो उन्हें क्रायोजेनिक्स और अल्ट्रालो फ्रीजर जैसी कम तापमान वाली प्रयोगशाला प्रक्रियाओं के लिए सबसे अच्छा विकल्प बनाता है। ये टीप्रकार -200 और 200 के बीच के माप के अनुरूप हैं। ये विघटनप्रतिरोधी भी हैं! इसलिए, संक्षारण प्रतिरोधी होने के कारण, इन प्रकारों का उपयोग आमतौर पर खाद्य उद्योग, फार्मास्यूटिकल्स और एचवीएसी अनुप्रयोगों में किया जाता है।

नोबल मेटल थर्मोकपल क्यों और कैसे महत्वपूर्ण हैं?

थर्मोकपल ऐसे उपकरण हैं जिनका उपयोग आमतौर पर औद्योगिक सेटिंग्स में उच्चतम क्रम के तापमान को मापने के लिए किया जाता है जहां वस्तुओं को अत्यधिक उच्च तापमान पर गर्म करने की आवश्यकता होती है। ये थर्मोकपल या तापमान सेंसर दो अलगअलग धातुओं से बने होते हैं जो तापमान को मापने के लिए एक विशेष जंक्शन पर मिलते हैं। दोनों धातुओं का ताप से अलगअलग संबंध होता है, इसलिए जब इस जंक्शन को गर्म किया जाता है, तो एक वोल्टेज उत्पन्न होता है। तापमान निर्धारित करने के लिए इस वोल्टेज को मापा जा सकता है।

नोबल मेटल थर्मोकपल अन्य धातुओं की तुलना में सबसे कम प्रतिक्रियाशील होते हैं!

यह उत्कृष्ट धातुओं की अद्वितीय प्रतिक्रियाशीलता विशेषता है जो उन्हें विशेष रूप से अत्यधिक तापमान स्थितियों में उपयोग करने के लिए उपयुक्त बनाती है। ये धातुएँ अन्य धातुओं की तरह प्रतिक्रियाशील नहीं होती हैं, इसलिए इनके संक्षारण की संभावना कम होती है। उनका गलनांक भी अधिक होता है, इसलिए वे उच्च तापमान का सामना कर सकते हैं। नोबल मेटल थर्मोकपल अन्य थर्मोकपल की तुलना में अधिक सटीक होते हैं, लेकिन वे अधिक महंगे भी होते हैं। रोडियम और प्लैटिनम दो ऐसी उत्कृष्ट धातुएँ हैं जिनका व्यापक रूप से अत्यधिक संवेदनशील और सटीक तापमान संवेदन उपकरण बनाने में उपयोग किया जाता है, भले ही वे महंगे हों। इनका उपयोग आमतौर पर उन उद्योगों में किया जाता है जहां सटीक तापमान माप महत्वपूर्ण होते हैं जैसे उच्च तापमान भट्टियां और बॉयलर।

नोबल मेटल थर्मोकपल के तीन मुख्य प्रकार हैं!

नोबल मेटल थर्मोकपल वे थर्मोकपल हैं जो अपनी सटीकता और परिशुद्धता के लिए जाने जाते हैं। उत्कृष्ट धातु थर्मोकपल के तीन मुख्य प्रकार हैं: आर प्रकार, एस प्रकार, और बी प्रकार। प्रत्येक प्रकार की तापमान परिवर्तन के प्रति अपनी संवेदनशीलता होती है।

  • आर प्रकार के थर्मोकपल रोडियम और प्लैटिनम से बने होते हैं जो तापमान परिवर्तन के प्रति सबसे अधिक संवेदनशील होते हैं और व्यापक तापमान रेंज, यानी -50 से 1400 डिग्री सेल्सियस तक काम करने में सक्षम होते हैं। इनका उपयोग अक्सर उन अनुप्रयोगों में किया जाता है जहां सटीक माप की आवश्यकता होती है, जैसे प्रयोगशालाओं में।
  • एस प्रकार के थर्मोकपल आर प्रकार के थर्मोकपल की तुलना में तापमान परिवर्तन के प्रति कम संवेदनशील होते हैं और उनकी सीमा -50 डिग्री सेल्सियस से 1200 डिग्री सेल्सियस होती है। वे पैलेडियम और प्लैटिनम से बने होते हैं और अक्सर औद्योगिक अनुप्रयोगों में उपयोग किए जाते हैं जहां सटीकता उतनी महत्वपूर्ण नहीं होती है। वे संक्षारण के प्रति अधिक प्रतिरोधी हैं, हालांकि आर प्रकार की तुलना में थोड़ा कम सटीक हैं।
  • बी प्रकार के थर्मोकपल सिलिकॉन और बोरॉन से बने सभी उत्कृष्ट धातु थर्मोकपल के तापमान परिवर्तन के प्रति सबसे कम संवेदनशील होते हैं। इनकी ऑपरेटिंग रेंज -50 डिग्री सेल्सियस से 1000 डिग्री सेल्सियस के बीच होती है।

नोबल मेटल थर्मोकपल तापमान मापने के लिए बहुत सटीक उपकरण हैं। आपके द्वारा चुने गए थर्मोकपल का प्रकार उस एप्लिकेशन के लिए आवश्यक संवेदनशीलता पर आधारित होना चाहिए जिसमें आप इसका उपयोग कर रहे हैं, जिसके लिए आप डोमेन विशेषज्ञों से पूछ सकते हैं जो आवश्यक तापमान संवेदनशीलता और अन्य शर्तों को पूरा करने के लिए आपके लिए अनुकूलित कर सकते हैं। आप उत्पादों की सर्वोत्तम श्रृंखला के लिए हीटकॉन से संपर्क करें।

 

 

 

थर्मोकपल अंशांकन की प्रक्रिया का विवरण

थर्मोकपल अंशांकन के बारे में

थर्मोकपल अंशांकन थर्मोकपल के तापमान माप की सटीकता को सत्यापित और समायोजित करने की प्रक्रिया है। इसमें थर्मोकपल के आउटपुट की तुलना ज्ञात तापमान पर एक संदर्भ मानक से करना और किसी भी विचलन या त्रुटि का निर्धारण करना शामिल है। अंशांकन यह सुनिश्चित करता है कि थर्मोकपल सटीक और विश्वसनीय तापमान रीडिंग प्रदान करता है, जिससे सटीक तापमान नियंत्रण और प्रक्रिया अनुकूलन की अनुमति मिलती है।

 

थर्मोकपल अंशांकन की तकनीकें

थर्मोकपल अंशांकन की 3 सामान्य विधियाँ हैं:

  • फिक्स्डपॉइंट थर्मोडायनामिक कैलिब्रेशन: इस विधि में, थर्मोकपल को ज्ञात तापमान के निश्चित बिंदुओं के विरुद्ध कैलिब्रेट किया जाता है, जैसे धातु या नमक जैसे शुद्ध पदार्थों के पिघलने बिंदु। निश्चित बिंदुओं के उदाहरणों में चांदी का हिमांक बिंदु (961.78°C) और पानी का त्रिगुण बिंदु (0.01°C) शामिल हैं। इन निश्चित बिंदुओं पर ज्ञात तापमान के साथ थर्मोकपल के आउटपुट की तुलना करके, अंशांकन समायोजन किया जा सकता है।
  • फर्नेस विधि: इसे स्टिरर्ड बाथ विधि भी कहा जाता है, इसमें थर्मोकपल को तापमान नियंत्रित स्नान या भट्टी में डुबोना शामिल है। स्नानघर या भट्ठी को पूरे क्षेत्र में एक स्थिर और समान तापमान प्राप्त करने के लिए डिज़ाइन किया गया है। तापमान को कैलिब्रेटेड रेफरेंस थर्मामीटर का उपयोग करके मापा जाता है। विभिन्न तापमानों पर थर्मोकपल और संदर्भ थर्मामीटर की रीडिंग की तुलना करके, अंशांकन सुधार निर्धारित किया जा सकता है।
  • ड्राई ब्लॉक कैलिब्रेटर: यह एक पोर्टेबल डिवाइस होता है जिसमें एक धातु ब्लॉक होता है जिसमें सटीक रूप से ड्रिल किए गए छेद होते हैं जहां थर्मोकपल डाला जा सकता है। अंतर्निहित हीटर या कूलर का उपयोग करके ब्लॉक को विशिष्ट लक्ष्य तापमान तक गर्म या ठंडा किया जाता है। ब्लॉक तापमान को कैलिब्रेटेड रेफरेंस थर्मामीटर का उपयोग करके मापा जाता है। अंशांकन के तहत थर्मोकपल को ब्लॉक में डाला जाता है, और इसके आउटपुट की तुलना संदर्भ थर्मामीटर रीडिंग से की जाती है, जिससे अंशांकन समायोजन की अनुमति मिलती है।

 

थर्मोकपल अंशांकन की आवश्यकता

विभिन्न उद्योगों में तापमान मापने के लिए थर्मोकपल का व्यापक रूप से उपयोग किया जाता है। हालाँकि, समय के साथ, उम्र बढ़ने, अत्यधिक तापमान के संपर्क में आने, यांत्रिक तनाव और पर्यावरणीय परिस्थितियों जैसे कारकों के कारण उनकी सटीकता कम हो सकती है। अंशांकन इन विचलनों को पहचानने और ठीक करने में मदद करता है, जिससे यह सुनिश्चित होता है कि थर्मोकपल सटीक तापमान रीडिंग प्रदान करता रहे।

 

थर्मोकपल अंशांकन के लिए आवश्यक आवृत्ति

कितनी बार थर्मोकपल अंशांकन की आवश्यकता होती है यह काफी हद तक विभिन्न कारकों पर निर्भर करता है, जैसे कि एप्लिकेशन का प्रकार जिसके लिए आपको थर्मोकपल की आवश्यकता है, उद्योग मानक, साथ ही नियामक आवश्यकताएं। सामान्य तौर पर, महत्वपूर्ण प्रक्रियाओं या सुरक्षामहत्वपूर्ण अनुप्रयोगों में उपयोग किए जाने वाले थर्मोकपल को अधिक बार कैलिब्रेट किया जाना चाहिए, आमतौर पर साल में एक बार से लेकर हर कुछ महीनों में एक बार। कम महत्वपूर्ण अनुप्रयोगों को हर 1-2 साल में अंशांकन की आवश्यकता हो सकती है।

 

अंतिम अंशांकन तिथि का निर्धारण

यह जानने के लिए कि अंतिम थर्मोकपल अंशांकन कब किया गया था, आपको उचित दस्तावेज़ और रिकॉर्ड बनाए रखना चाहिए। मान्यता प्राप्त अंशांकन प्रयोगशालाओं द्वारा प्रदान किए गए अंशांकन प्रमाणपत्रों में आम तौर पर अंशांकन तिथि, नियत तारीख और अन्य प्रासंगिक जानकारी शामिल होती है। इसलिए इन प्रमाणपत्रों पर नज़र रखना या अंशांकन लॉग बनाए रखना महत्वपूर्ण है ताकि यह सुनिश्चित किया जा सके कि थर्मोकपल अपने अंशांकन शेड्यूल के भीतर बना रहे।

 

गुणवत्ता प्रमाणपत्र

थर्मोकपल को मान्यता प्राप्त अंशांकन प्रयोगशालाओं द्वारा प्रमाणित या कैलिब्रेट किया जा सकता है जो आईएसओ/आईईसी 17025 जैसे अंतरराष्ट्रीय मानकों का पालन करते हैं। ये प्रयोगशालाएं ट्रेस करने योग्य संदर्भ मानकों का उपयोग करती हैं और अंशांकन करने के लिए योग्य कर्मियों को नियुक्त करती हैं। इन प्रयोगशालाओं द्वारा प्रदान किए गए अंशांकन प्रमाणपत्र थर्मोकपल की सटीकता और गुणवत्ता मानकों के अनुपालन के प्रमाण के रूप में काम करते हैं।

 

सर्वोत्तम थर्मोकपल की खरीद के लिए

थर्मोकपल अंशांकन के लिए अलगअलग दृष्टिकोण पेश करने वाली विभिन्न विधियाँ हैं, और विधि का चुनाव आवश्यक सटीकता, उपलब्ध उपकरण और विशिष्ट अनुप्रयोग जैसे कारकों पर निर्भर करता है। सर्वोत्तम थर्मोकपल की खरीद के लिए, आप हीटकॉन सेंसर्स के पास सकते हैं, जिनकी टीम आपको सबसे उच्च गुणवत्ता वाले उत्पाद प्रदान करने का वादा करती है।

 

 

 

थर्मोकपल कनेक्टर्स और किसी एक को चुनते समय ध्यान देने योग्य बातें!

थर्मोकपल कनेक्टर ऐसे उपकरण हैं जिनका उपयोग तापमान मापने के लिए उपकरण के दो टुकड़ों को एक साथ जोड़ने के लिए किया जाता है। मूल रूप से, थर्मोकपल कनेक्टर किसी भी औद्योगिक प्रक्रिया में उपकरण का एक महत्वपूर्ण हिस्सा है जिसमें उच्च तापमान शामिल होता है।

  • थर्मोकपल मिश्रथर्मोकपल मिश्र धातु दो अलगअलग धातुओं से बने होते हैं जो एक छोर पर एक साथ जुड़े होते हैं। फिर थर्मोकपल के दूसरे सिरे को सॉकेट में डाला जाता है। थर्मोकपल मिश्र धातुएँ ऐसी धातुएँ हैं जिनका उपयोग थर्मोकपल बनाने के लिए किया जाता है। वांछित गुणों के आधार पर कई अलगअलग मिश्र धातुएं उपयोग की जा सकती हैं। सबसे आम थर्मोकपल मिश्र धातु कॉपरकॉन्स्टेंटन, क्रोमेलएलुमेल, आयरनकॉन्स्टेंटन और प्लैटिनमरोडियम हैं। प्रत्येक मिश्र धातु में अलगअलग गुण होते हैं जो इसे विभिन्न अनुप्रयोगों के लिए उपयुक्त बनाते हैं। उदाहरण के लिए, कॉपरकॉन्स्टेंटन का उपयोग अक्सर उच्च तापमान अनुप्रयोगों में किया जाता है, जबकि क्रोमेलएलुमेल कम तापमान अनुप्रयोगों के लिए बेहतर अनुकूल है।

General Purpose Thermocouples

Mineral Insulated Thermocouples

Molded Transition Thermocouples

 

Thermocouples are crucial temperature-sensing devices used across various industries for their reliability, accuracy, and ruggedness. As the demand for precise temperature measurements grows, the role of thermocouple manufacturers becomes increasingly significant. The manufacturers specialize in crafting thermocouples tailored to meet the diverse needs of industries such as aerospace, manufacturing, automotive, healthcare, and more. Let us delve into the three common types of thermocouples produced by a thermocouple manufacturer: which are (i) General Purpose Thermocouples, (ii) Mineral Insulated Thermocouples, and (iii) Moulded Transition Thermocouples.

Types of Thermocouples

Thermocouples are temperature-sensing devices that consist of 2 different metal wires joined together at one end. When exposed to a temperature gradient, they generate a voltage, known as the thermoelectric voltage, which is proportional to the temperature difference between the two junctions. There are several types of thermocouples, each made from different combinations of metals, and they are categorized based on their temperature range, sensitivity, and application suitability. Some of the most common types of thermocouples are mentioned underneath in detail:

  • General Purpose Thermocouples: These thermocouples are also known as Base-Metal Thermocouples. These are temperature sensors used to measure temperature in a wide range of applications across various industries. They are the most commonly used type due to their simplicity, reliability, versatility & cost-effectiveness. Such thermocouples offer reliable performance in many scenarios, making them a popular choice for a wide range of temperature measurement needs. These consist of 2 different metal wires that are joined together at one end to form a junction. The junction is exposed to the temperature being measured, while the other ends of the wires are connected to a measuring instrument. When there is a temperature difference between the two junctions (the measuring junction and the reference junction), an electromotive force (EMF) is generated. This EMF is directly related to the temperature difference and can be measured by the temperature measuring instrument, which then provides a temperature reading.
  • Mineral Insulated Thermocouples: Mineral-Insulated or MI Thermocouples are designed for more demanding & harsh environments. These thermocouples consist of 2 thermocouple wires placed inside a compacted, high-temperature-resistant mineral insulating material, typically magnesium oxide (MgO). The outer sheath can be made of stainless steel or other high-temperature alloys. Their construction provides exceptional protection against moisture, chemicals, and mechanical damage, making them ideal for applications in industrial processes, aerospace, and laboratories. The compact design allows for faster response times and high accuracy in extreme temperature conditions. Thermocouple manufacturers often customize the MI Thermocouples to meet specific customer requirements, ensuring they can withstand temperatures ranging from -200°C to over 1000°C. Their ruggedness & reliability make them suitable for applications in severe environments like exhaust gas measurements, petrochemical processing, and metal smelting. They are constructed using base metal alloys, such as Type K (Chromel-Alumel), Type J (Iron-Constantan), and Type T (Copper-Constantan). Each type has its own temperature range and characteristics, making them suitable for different applications. 
    • Type K: The Chromel-Alumel combination can withstand temperatures ranging from -200°C to approximately 1260°C. This type of thermocouple is widely used in various industries, including food processing, automotive, and power generation.
    • Type J: The Iron-Constantan combination can operate in a temperature range of -210°C to around 760°C. Its lower temperature limit makes it unsuitable for extremely high-temperature applications.
    • Type T: The Copper-Constantan combination covers a temperature range of -200°C to approximately 370°C. Such type of thermocouple is commonly used in cryogenics, environmental chambers, and HVAC systems.
  • Molded Transition Thermocouples: Molded-Transition Thermocouples are the type of thermocouples specifically designed for surface temperature measurements. They consist of a sensing junction that is embedded in a molded insulating material, such as ceramic or epoxy, to protect the junction and provide electrical insulation. The other end of the thermocouple has a lead wire that connects to the measuring instrument. Their primary advantage is their ease of installation and ability to measure temperature on flat or curved surfaces. They are commonly used for applications in the plastics industry, semiconductor manufacturing, and research labs. Their unique & compact design helps in situations where space is a concern. While these thermocouples provide accurate measurements for surface temperatures, they may not be suitable for extremely high-temperature applications. Thermocouple manufacturers can customize the materials and dimensions of Molded Transition Thermocouples to meet the unique requirements of their customers.

Frequency Needed for Calibration

 

Thermocouple calibration is the process of verifying & adjusting the accuracy of a thermocouple’s temperature measurement. It involves comparing the output of a thermocouple to a reference standard at known temperatures and determining any deviations or errors. Calibration ensures that the thermocouple provides accurate & reliable temperature readings, allowing for precise temperature control and process optimization.

Techniques of Thermocouple Calibration

There are 3 common methods of  calibration:

  • Fixed-Point Thermodynamic Calibration: In this method, the thermocouple is calibrated against fixed points of known temperatures, such as the melting points of pure substances like metals or salts. Examples of fixed points include the freezing point of silver (961.78°C) and the triple point of water (0.01°C). By comparing the output of the thermocouple with the known temperatures at these fixed points, calibration adjustments can be made.
  • The Furnace Method: Also called as the Stirred Bath method, this involves immersing the thermocouple in a temperature-controlled bath or furnace. The bath or furnace is designed to achieve a stable & uniform temperature throughout. The temperature is measured using a calibrated reference thermometer. By comparing the readings of the thermocouple and the reference thermometer at different temperatures, calibration corrections can be determined.
  • Dry Block Calibrator: This happens to be a portable device that consists of a metal block with precision-drilled holes where the thermocouple can be inserted. The block is heated or cooled to specific target temperatures using built-in heaters or coolers. The block temperature is measured using a calibrated reference thermometer. The thermocouple under calibration is inserted into the block, and its output is compared to the reference thermometer readings, allowing for calibration adjustments.

The Need for Thermocouple Calibration

Thermocouples are widely used for temperature measurement in various industries. However, over time, their accuracy may drift due to factors such as aging, exposure to extreme temperatures, mechanical stress, and environmental conditions. Calibration helps identify & correct these deviations, ensuring that the thermocouple continues to provide accurate temperature readings.

Frequency Needed for Thermocouple Calibration

How often calibration is needed largely depends on different factors, such as the type of application for which you need thermocouple, industry standards, as well as regulatory requirements. In general, thermocouples used in critical processes or safety-critical applications should be calibrated more frequently, typically ranging from once a year to once every few months. Less critical applications may require calibration every 1-2 years.

Determining the Last Calibration Date

To know when the last calibration was done, you should maintain proper documentation & records. Calibration certificates provided by accredited calibration laboratories typically include the calibration date, due date, and other relevant information. It is thus important to keep track of these certificates or maintain a calibration log to ensure the thermocouple remains within its calibration schedule.

Quality Certifications

Thermocouples can be certified or calibrated by accredited calibration laboratories that follow international standards, such as ISO/IEC 17025. These laboratories use traceable reference standards and employ qualified personnel to perform the calibration. Calibration certificates provided by these laboratories serve as evidence of the thermocouple’s accuracy & compliance with quality standards.

Troubleshoot Thermocouple Malfunction

A thermocouple is a device used to measure temperature by utilizing the principle of the Seebeck effect. It consists of two different metal wires or alloys, known as thermocouple wires, joined together at one end to form a junction. When there is a temperature difference between the junction and the other end of the thermocouple, it generates a voltage that is proportional to the temperature difference. Thermocouple malfunction is a problem you can face!

Reasons of Thermocouple Malfunction

Here are some common issues:

  • Contamination: If the thermocouple gets contaminated with dirt, soot, or other substances, it can affect its ability to generate an accurate voltage. Contamination can occur due to improper combustion, poor ventilation, or a buildup of debris over time.
  • Damage or wear: Physical damage to the thermocouple, such as frayed wires, bent or broken junction, or corrosion, can disrupt the flow of electrical signals and result in a malfunction. Additionally, regular wear and tear can degrade the performance of the thermocouple over time.
  • Loose connections: Loose or faulty connections between the thermocouple and the gas valve or controller can lead to intermittent or no voltage output. 
  • Faulty pilot light: In gas-powered systems, the pilot light heats the thermocouple to generate the necessary voltage. If the pilot light is not functioning correctly or is not heating the thermocouple adequately, it can result in a malfunctioning thermocouple.
  • Aging or deterioration: Like any other electronic component, thermocouples can deteriorate over time due to aging. This can lead to reduced sensitivity or inaccurate temperature readings.

How to Know if the Thermocouple Is Working?

To determine if a thermocouple is working, you can perform an open circuit test. If the voltage reading is within the expected range and remains stable during the test, it suggests that the thermocouple is functioning properly. However, if the voltage reading is too low or unstable, it may indicate a faulty thermocouple that needs to be replaced.

Steps for Open Circuit Test

  • First, put off the supply of gas.
  • Then, locate the thermocouple.
  • After that, inspect it.
  • Now, disconnect it.
  • After that, measure the voltage.
  • Then, apply heat.
  • You need to monitor the multimeter now.
  • Finally, check for a stable reading.

Know of Thermocouple Malfunction

You can follow these steps:

  • Check for a pilot light: In many cases, thermocouples are used in gas-powered systems, such as furnaces or water heaters, to detect the presence of a pilot light. If the pilot light is not staying lit, it could be a sign of a faulty thermocouple.
  • Test the voltage: Use a multimeter to measure the voltage generated by the thermocouple. Disconnect the thermocouple from the gas valve or controller and place the multimeter probes on the two leads of the thermocouple wires. Heat the junction of the thermocouple with a flame (e.g., a lighter) while monitoring the multimeter. If you don’t observe a change in voltage as the temperature increases, it may indicate a malfunctioning thermocouple.
  • Inspect for physical damage: Visually inspect the thermocouple for any signs of physical damage, such as frayed wires, corrosion, or loose connections. If you notice any damage, it could affect the performance of the thermocouple.

Troubleshoot Thermocouple Malfunction

You can perform the following steps:

  • Inspect the thermocouple & clean if required: Visually inspect the thermocouple for any signs of physical damage, contamination, or loose connections. Clean the thermocouple if necessary.

You Need to Know about the Thermocouple Temperature Measurement Errors!

Most Common Reasons for Thermocouple Temperature Measurement Errors

Heatcon as Your Go-To Purchase Destination

Thermocouples happen to be amongst the most well-known instruments for measuring temperature in the various types of industrial settings owing to their awesome versatility and easy usage. But thermocouple temperature measurement errors can still occur. 

Most Common Reasons for Thermocouple Temperature Measurement Errors

Though these devices are quite reliable, thermocouple temperature measurement errors can always occur because of different causes. Let us discuss some of the most common reasons for such errors along with the solutions to rectify them:

  • Choosing the Inappropriate Thermocouple Type on Transmitter: Different thermocouples like type K, type J, type N, type E, type T, type R, type S, & type B etc., are all designed differently to measure different temperature ranges, accuracies, electric outputs, and have different sensitivities. Using the wrong type of thermocouple can result in inaccurate temperature measurements, which happens to be a common error.
  • Issues with the Thermocouple’s Extension Wires: The extension wire used to connect the thermocouple to the measurement device can introduce errors if it is of poor quality or not compatible with the thermocouple type. Factors such as resistance, insulation, and electromagnetic interference can affect the accuracy of the temperature measurement. If one accidentally reverses thermocouple lead wires’ polarity, then the temperature being measured would become wrong due to the difference in the temperatures of the 2 leads ends. The issue is very much fathomable as red is the usual colour for positive charges, however the red wire inside thermocouple’s cables usually has negative signal. Such coloration is in the thermocouples’ ANSI-standard, however it’s not what many people tend to expect.
  • Innate Differences in the Alloys: Thermocouples rely on the principle of thermoelectric effect, where temperature differences generate voltage. However, there can be variations in the alloys used to construct thermocouples, which can result in inconsistent voltage outputs and measurement errors. Remember, no 2 batches of wires would be totally similar. As alloy percentages tend to vary during each process, errors in thermocouple accuracies tend to be inevitable. 
  • Variations in the Temperatures Around Reference Junction’s Connection: Thermocouples require a reference junction to measure temperature accurately. If the temperature at the reference junction deviates from the assumed value, it can introduce erroneous measurement of temperatures. Factors such as ambient temperature fluctuations and poor thermal contact can affect the reference junction temperature.
  • Thermocouple Grounded at Multiple Locations: Grounding a thermocouple at more than one location can create additional thermoelectric junctions, which can introduce errors in the measurement. These additional junctions can generate unwanted voltages that interfere with the desired temperature measurement. If grounded at multiple locations, a “ground loop” could be formed with the current flowing through the thermocouple from 1 specific ground to another. This may tend to creäte electromagnetic fields that can cause radio-frequency-interference-related issues, which may tend to affect the measurement accuracy.
  • Age of the Thermocouple: Over time, thermocouples can degrade due to factors such as corrosion, oxidation, or contamination. This can lead to changes in the thermocouple’s electrical properties, resulting in measurement errors. Regular calibration and replacement of aging thermocouples are necessary to maintain accuracy. Max temperature exposure, cyclic measurement, & frequency of cycles may tend to impact the metallurgy resulting in such a drift, which is mostly downwards. Sadly, such a drift can’t be forecasted, but 10-20 degrees F errors are quite common.

What Are Thermocouples?

Thermocouples are temperature sensors that consist of two different metal wires joined together at one end. They tend to generate voltages proportional to temperature differences between the junction & wire’s other end. Thermocouples are widely used because they are durable, inexpensive, and can measure a wide range of temperatures. They are commonly employed in various industrial and scientific applications, including temperature monitoring in ovens, furnaces, engines, and electronic devices.

How Do Thermocouples Work? 

Thermocouples are widely used temperature sensors that operate based on the principle of the Seebeck effect. They consist of two dissimilar metal wires joined together at one end, forming a junction. When there is a temperature gradient between the junction and the other end of the wires (known as the reference junction), a voltage is generated across the thermocouple, which is proportional to the temperature difference. Such a phenomenon is called the Seebeck effect. When the junction of the two wires is exposed to a temperature gradient, an electric potential is created across the wires due to the differing electron densities and energy levels of the metals. This potential difference is measured and used to determine the temperature at the junction.

Most Common Temperature Ranges of Different Thermocouple Types

The temperature ranges of thermocouples cover a wide variety of applications, from cryogenic temperatures to extremely high-temperature environments. It is important to select the appropriate thermocouple type that suits the temperature range of your specific application. Here are some most common temperature ranges for different thermocouple types:

  • Type K: -200°C to 1350°C (-328°F to 2462°F)
  • Type J: -210°C to 760°C (-346°F to 1400°F)
  • Type T: -200°C to 370°C (-328°F to 698°F)
  • Type E: -200°C to 900°C (-328°F to 1652°F)
  • Type R: 0°C to 1450°C (32°F to 2642°F)
  • Type S: 0°C to 1450°C (32°F to 2642°F)
  • Type B: 600°C to 1700°C (1112°F to 3092°F)
  • Type C: 0°C to 2320°C (32°F to 4190°F)
  • Type D: 0°C to 2320°C (32°F to 4190°F)

How to Accurately Measure Temperature Using Thermocouples?

To accurately measure temperature, thermocouples require a reference junction, often achieved using an ice bath or a dedicated temperature sensor. Additionally, the voltage generated by a thermocouple is typically small, so amplification or signal conditioning may be necessary to obtain a usable temperature reading.

Accuracies & Temperature Ranges of Different Thermocouple Types?

All thermocouple types have their own temperature ranges & accuracy characteristics. The accuracy of a thermocouple is influenced by factors such as the wire material, manufacturing quality, and the reference junction temperature measurement technique. Generally, the accuracy of base metal thermocouples ranges from ±1 to ±10 degrees Celsius, while noble metal and refractory metal thermocouples offer higher accuracy in the range of ±0.5 to ±1 degree Celsius.

Why Do Various Thermocouple Types Differ in Their Colours?

Thermocouples are color-coded to help users easily identify the type. The colour of the thermocouple wire and the colour of the connector can vary depending on the thermocouple type. The colours provide a quick visual reference for selecting the appropriate thermocouple and ensuring accurate temperature measurements.

Thermocouple Types

There are several thermocouple types, categorized based on the metals used in their construction. The most common types include base metal thermocouples (Type J, Type T, Type E, and Type N), noble metal thermocouples (Type R, Type S, Type C, and Type GB), and refractory metal thermocouples. Each type has specific temperature ranges and characteristics. They are identified by letters assigned to them based on the metals used in their construction.

Differences in Thermocouple Types

Each of the calibrations has a different environment & different temperature range, though the max temperature tends to vary with the wire’s diameter that is being utilised in thermocouples. Though thermocouple’s calibration tends to dictate its temperature range, still the max range is even limited by the wire’s diameter. So, a thin thermocouple might not be able to reach its complete temperature range.

Base Metal Thermocouple Types

  • Type K: Composed of Chromel (Nickel-Chromium) and Alumel (Nickel-Aluminum). Suitable for general-purpose applications and has a wide temperature range (-200°C to 1350°C).
  • Type J: Consists of Iron and Constantan (Copper-Nickel). Often used in low-temperature applications (-210°C to 760°C).
  • Type T: Made of Copper and Constantan. Suitable for cryogenic and low-temperature measurements (-200°C to 370°C).
  • Type E: Comprises Chromel and Constantan. Exhibits good accuracy at moderate temperatures (-200°C to 900°C).
  • Type N: This is made of Nicrosil (74.1 % nickel – 14.4 % chromium – 1.4 % silicon.0.1 % magnesium) & Nisil (95.6 % nickel to 4.4 % silicon). 

Noble Metal Thermocouple Types

  • Type R: Made of Platinum and Platinum-Rhodium (13% Rhodium). Suitable for high-temperature applications (0°C to 1450°C).
  • Type S: Composed of Platinum and Platinum-Rhodium (10% Rhodium). Also used for high-temperature measurements (0°C to 1450°C).
  • Type B: Consists of Platinum-Rhodium alloys (30% Rhodium and 6% Rhodium). Suitable for extremely high-temperature environments (600°C to 1700°C).

Refractory Metal Thermocouple Types

  • Type C: Composed of Tungsten and Tungsten-Rhenium (5% Rhenium). Suitable for ultra-high-temperature measurements (0°C to 2320°C).
  • Type D: Made of Tungsten and Tungsten-Rhenium (3% Rhenium). Used for high-temperature applications (0°C to 2320°C).
  • Type G: These are called WM26Re technically. These have an alloy combination with tungsten (W) & tungsten + 26 % rhenium (W-26 % Re). The maximum operating temperature of this type G is 0 degree Celsius to 2320-degree Celsius. 

Why Is Type K So Much Popular?

Among the various thermocouple types, Type K thermocouples are particularly popular due to their wide temperature range, good accuracy, and relatively low cost. They can be used in a variety of applications, ranging from industrial processes to scientific research. The popularity of Type K thermocouples can be attributed to their versatility, reliability, and availability. The conductor materials that are being utilised this Type K thermocouple tend to be more chemically inert than other types such as Type T & Type J. Though the output of Type K ones tends to be somewhat lower than other Types including Type T, Type J & Type E, still it’s much higher than its nearest competitor (i.e., Type N) & is being in use from pretty long now. 

How to Select the Most Ideal One?

When choosing between different thermocouple types, consider factors such as the temperature range of your application, required accuracy, environmental conditions, and cost. Consult the specifications of the thermocouple types to ensure that you select a thermocouple that meets your specific needs. Additionally, it’s important to consider the compatibility of the thermocouple with the measuring instrument or data acquisition system you intend to use. When choosing between different thermocouple types, there are several factors to consider, as follows: 

  • Temperature Range: One of the primary factors is the temperature range of your application. Different thermocouple types have different temperature limitations, so you need to select a thermocouple that can accurately measure the temperatures you will encounter. If you know the temperature range of your application, you can compare it to the temperature ranges of various thermocouple types. Choose a thermocouple that can comfortably operate within your desired temperature range. Ensure that the chosen thermocouple has a temperature range that covers both the minimum and maximum temperatures you expect to measure. For example, if your application involves measuring temperatures up to 1000°C, a Type K or Type R thermocouple would be suitable since they have temperature ranges that include that range. 
  • Consider Accuracy Requirements: Another important consideration is the required accuracy of temperature measurements. Different thermocouple types have varying accuracy levels, which may be specified by the manufacturer. If you have specific accuracy requirements for your application, ensure that the chosen thermocouple can meet those requirements. Keep in mind that accuracy can also be influenced by factors such as the quality of the thermocouple construction, the calibration process, and the measurement instrumentation used. It’s essential to consider the overall accuracy of the entire measurement system, including the thermocouple and associated equipment.
  • Consider Environmental Conditions: The environmental conditions in which the thermocouple will be used should also be considered. Factors such as corrosive atmospheres, vibrations, and pressure can impact the performance and lifespan of the thermocouple. Some thermocouple types are better suited for specific environments. For example, Type K thermocouples are known for their resistance to oxidation and are often used in industrial applications. On the other hand, Type T thermocouples are suitable for cryogenic applications due to their stability at low temperatures. Consider the specific environmental conditions in which the thermocouple will be exposed and choose a thermocouple type that can withstand those conditions effectively.
  • Consider Cost: The cost of the thermocouple is also an important factor to consider. Thermocouples vary in terms of material composition, manufacturing processes, and availability, which can affect their prices. Evaluate your budget and select a thermocouple that meets your temperature measurement needs while staying within your financial constraints.
  • Conductor Size: Thermocouple wires diameter also required to be considered when long measurements need to be taken. For instance, Type T thermocouples have been rated to 370C/700F, but if the thermocouple has #14AWG wires (with .064” as the diameter) then these are rated for 370C/700F. If the thermocouple that you choose has #30AWG wires, which drops to 150C/300F. 
  • Others: Other crucial considerations tend to be the sheath material (in the immersion probe style), the insulation materials (in case of wires/surface sensors) & sensor geometry.

How to Choose the Right Cartridge Heater?

Some FAQs about Cartridge Heaters

What Are Cartridge Heaters?

Cartridge heaters are tube-shaped types of electric heating elements that could possibly be inserted into drilled holes. These happen to be cylindrical in shape and are commonly used for heating applications. It consist of metal sheaths (usually stainless steel) that encloses a heating coil made of a high-resistance wire, such as nichrome. They tend to give quite localized & very precise heating. These are usually utilized in the heating processes in various industries. The heating coil is wound tightly around a ceramic or magnesium oxide core, which provides electrical insulation and efficient heat transfer. Normally, a cartridge heater tends to be utilised for heating metal blocks from inside. Also, these could be customised to specific watt densities that are based upon the needs of the applications. These heaters are quite often used to heat metal parts by making insertions into drilled holes. For speedy & simple installations, these heaters tend to be made somewhat undersized as compared to their usual diameters.

How Do Cartridge Heaters Work?

These heaters work based on the principle of electrical resistance heating. When an electric current is passed through the heating coil, it generates heat due to the resistance offered by the wire. This heat then gets transported to the containing environment via conduction. Cartridge heaters contain resistive coils wound around by ceramic cores, which are further surrounded by dielectrics that are encased inside metal sheaths. Electrically powered heat transferred through the coils to sheaths tend to cause the sheaths to get heated up. This heat is further transmitted to the metal part that needs to be heated. General purpose drills are generally suitable for drilling holes for installing cartridge heaters in low-to-medium temperature applications (600-degree F or lesser than than). Holes could be drilled 0.003″ to 0.008″ over the supposed size of the drill, yielding 0.009″ to 0.04.” Although this particular fit is a little looser than would allow for optimum transfer of heat, it does help while installing & removing these  heaters, specifically those with longer sheaths. For high power, density is much more significant. Holes must be drilled & countersunk, not simply drilled with a general-purpose bit. All thanks to the tighter fit, the heaters run cooler and have a longer service shelf life.

Operating Temperatures of Cartridge Heaters

The operating temperature of a cartridge heater can vary depending on its design and intended application. However, they are typically capable of reaching temperatures ranging from around 200°C (392°F) up to 1000°C (1832°F) or even higher, depending on the specific design and construction. A cartridge heater could possibly operate at low watt densities, medium watt densities, & even at high watt densities. These have been designed in such a way that they can withstand working temperatures of even up to as large as 1400°F. But the optimum operating temperatures would largely depend upon the kind of application it is being used for. You must also understand that there are several other factors too, which could possibly affect the actual temperatures of industrial heaters & the monitored temperatures of materials during such heating cycles; these factors include watt densities of the cartridge heaters, their tightness inside holes, & thermal conductivity of the said material that is being heated. For applications that involve high temperatures, like the ones above 1000°F, sheathes of incoloy material are usually advisable for max heat transfer & fine durability. It’s even significant if you consider electrical termination of cartridges as per the operating temperatures. When the cartridge heaters are utilised at fairly high temperatures, the electric terminals must be either different than the common lead wires of high temperatures or these cartridges must be designed in such a way that the temperatures surrounding the lead wires are well-maintained at much lower temperatures than the limits of the temperatures of those particular lead wires.

What Is a Cartridge Heater Utilised for?

Cartridge heaters find applications in various industries & processes where localized heating is required. Some common uses include the following:

  • Plastic injection moulding: Cartridge heaters are often used to heat the nozzles or the hot runner systems of injection moulding machines.
  • Packaging and sealing equipment: They are used for heat sealing applications in packaging machines, such as sealing plastic bags or containers.
  • Hot stamping: Cartridge heaters provide the necessary heat for hot stamping machines used in marking or branding processes.
  • Food processing: Cartridge heaters can be used in ovens, cooking equipment, or other food processing applications where localized heating is needed.
  • Heating gases & liquids: Cartridge heaters can be used to heat liquids or gases by immersing them directly into the medium or through indirect heating methods like heat transfer through pipes or vessels.
  • Other uses: Cartridge heaters are often used in hot runner moulds, semiconductors, medical equipment, laminating presses, scientific equipment etc. 

Temperature Sensors & Temperature Controllers for Cartridge Heaters

To control the temperature of cartridge heaters, temperature controllers are utilized. Temperature controllers are devices that monitor & regulate the temperature of the heating element. They typically include a temperature sensor, a control mechanism, and an output to adjust the power supplied to the cartridge heater. Temperature sensors for cartridge heaters are commonly either thermocouples or resistance temperature detectors (RTDs). Thermocouples are made of two different metals joined together, which produce a voltage proportional to the temperature difference. RTDs, on the other hand, use the principle of the change in electrical resistance of a metal with temperature. Both types of sensors provide temperature feedback to the temperature controller. The temperature controller receives input from the temperature sensor and compares it to the desired set temperature. Based on this comparison, the controller adjusts the power supplied to the cartridge heater to achieve and maintain the desired temperature. This is usually done using a feedback control loop that continuously monitors and adjusts the power output.

How to Choose the Right Cartridge Heater?

Choosing the right cartridge heater requires considering several factors to ensure it meets your specific requirements. Here are some key considerations when selecting a cartridge heater:

  • Operating temperature: Determine the maximum temperature required for your application. Cartridge heaters come in various temperature ratings, so select one that can withstand the desired operating temperature without compromising performance or safety.
  • Wattage & voltage: Determine the power requirements of your application, including the wattage and voltage. Ensure the cartridge heater you choose matches these requirements to provide the necessary heating power.
  • Size & shape: Consider the dimensions and shape of the cartridge heater. It should fit properly into the intended heating location or equipment. Consider the length, diameter, and any specific shape requirements to ensure a proper fit.
  • Material & sheath: Choose the appropriate sheath material based on the environment and application conditions. Stainless steel is commonly used for its durability, corrosion resistance, and ability to handle high temperatures. However, other materials like Incoloy or titanium may be suitable for specific applications.
  • Lead wire options: Cartridge heaters typically have lead wires for electrical connection. Determine the length, type (such as fiberglass insulated or silicone insulated), and connection options (such as leads with connectors or bare leads) that best suit your application.
  • Mounting options: Consider how the cartridge heater will be mounted or installed. Different heaters may have specific mounting options such as threaded fittings, flanges, or other custom options. Ensure the mounting method aligns with your requirements.
  • Special features: Depending on your application, you may need additional features such as built-in temperature sensors (thermocouples or RTDs) for precise temperature control or specific insulation options for electrical safety.
  • Application requirements: Consider any additional requirements specific to your application, such as compatibility with certain chemicals, moisture resistance, or resistance to vibrations or shocks.

Some FAQs about Cartridge Heaters

These FAQs provide a general understanding of cartridge heaters and address some common questions. However, specific details and requirements may vary depending on the intended application.

Liquid’s Temperature Measurement Using an RTD

Measuring Air & Gas Temperatures Using RTD Sensors

Measuring Surface Temperatures

 

Introducing Resistance-Temperature-Detectors (RTDs)

These happen to be the temperature sensors that tend to consist of a resistor, which alters the resistance value when there are changes in the temperature. These are being used for several years now for measuring temperatures in labs & other industrial processes. These have formed a good reputation for repeatability, accuracy, & stability. Most of the elements of an RTD contain a finely twisted wire that is wound around a glass core or a ceramic. The element is generally very delicate; therefore, it’s usually located in a sheathed protective probe. The RTD element happens to be built of pure materials for withstanding varied temperatures. Material’s resistance changes predictably when there are changes in the temperature; that predicted change is usually utilized for determining the temperatures.

The Origin 

Sir Humphrey Davy saw that metals resistivity showed considerable temperature dependence, and this discovery happened in the same year in which Seebeck discovered thermoelectricity. After 50 years, Sir William Siemens proposed using platinum as the resistance ‘s element.

Advantages of Using RTDs

The resistance temperature detector happens to be the most accurate temperature sensor. In addition to good accuracy, it also offers great stability & excellent repeatability. Such an RTD is even relatively immune to electric noises and are thus suited for temperature measurement in different industrial environments, specifically near generators, motors, & other such high voltage equipment.

RTD Probe’s Construction 

Such probes are the assemblies consisting of one element, one sheath, one lead wire & one terminal/connection. Once the element has been chosen, the wiring & packaging needs are to be decided. Sensors can be connected in many ways & there are unlimited sensors or sensor structures to make the selection.

Wiring Arrangement

For measuring temperatures, the element of the RTD should be joined to a monitoring/control device. Now, as the measurement of the temperature is entirely based upon the resistance of the element, any other resistance that has been added to that circuit (resistance of wires, connections, etc.) can lead to an error in the measurement. Any other wiring than the two-wire configuration allows control/monitoring of the devices to account for unwanted wire resistance & other such resistances inside that circuit. Sensors using a three-wire design happen to be quite common designs utilised for industrial processes as well as monitoring/control applications. The resistance of the wires is considered, provided that all the lead wires are having similar resistance; else errors may occur.

Materials of the Wires

While determining the materials of the lead wire, the correct wires must be selected based on the temperature & environment to which that sensor would be exposed during operation. Temperature is by far the most crucial factor in wire selection, but physical properties like abrasion resistance & water submersion properties could be significant too. The 3 widely popular structures are given as under: 

  • PVC insulated probe provides the temperature range of -40 degrees Celsius to 105 degrees Celsius. It also has nice wear resistance. It is also suitable for water immersion. 
  • PFA insulated RTD probe provides the temperature range of -267 degrees Celsius to 260 degrees Celsius. It also provides supercool wear resistance. It is even perfect for water submersion applications. 
  • Although an RTD probe with fiberglass insulation tends to provide a higher temperature range from -73 to 482 degrees Celsius, its performance is considered less effective when consumed or immersed in water.

The Termination

An RTD probe might be stopped via a connection end, or through a quick disconnect, or by a terminal block or even by an extension wire. There are other finishing styles too. 

The Configuration

As the RTD element, the wire layout & the wire structuring have been chosen, the physical structuring of the sensor must be acknowledged. The configuration of the final sensor largely depends on the type of application needed. Varied sensor configurations are needed for measuring the temperatures of liquids, surfaces, or gas streams.

Widely Popular RTD’s Resistance Materials

  • Platinum (highly accurate & widely popular)
  • Nickel
  • Copper
  • Balco (very rare)
  • Tungsten (quite rare)

RTD standards

There happen to be 2 standards for a platinum RTD. These are 1) the European standard (which is even called IEC standard or the DIN) and 2) the American standard. The European one has been considered the global platinum RTD standard. This particular standard, DIN/IEC 60751 (or only IEC751), needs the RTD for having an electric resistance of 100.00 Ω at 0 degrees Celsius, & also the temperature-coefficient-of-resistance (i.e., the TCR) of 0.00385 Ω/Ω/degree Celsius between 0 degree Celsius & 100 degree Celsius. The amalgamation of temperature coefficient & resistance tolerance tends to determine the resistance & temperature characteristics of such an RTD sensor. The greater is the tolerance of the element, the more the sensor deviates from the general curve & greater will be the variability from 1 sensor to another (which is also called interchangeability). This is significant for those users who require the replacement of sensors & need to curtail any interchangeability errors.

Selecting the Most Ideal RTD 

  • RTD Element: This is RTD’s simplest form. This contains one piece of wire that is wrapped around a glass core or a ceramic. Owing to their small size, such an element is usually utilised where space is quite limited.  
  • RTD Surface Element: This happens to be a special RTD element type. This is made pretty thin, which ensures nice contact for measuring temperatures on a flat surface.  
  • RTD Probe: This happens to be a highly robust RTD form. This contains an RTD element, which has been mounted in a metal tube, which is also called sheath that safeguards the element from the environment.

FAQs

  • Why should one be using an RTD rather than a thermistor sensor or a thermocouple? All types of temperature sensors have specific conditions for which they are ideal. As far as RTDs are concerned, with a wide temperature range up to even 850 degrees Celsius, they could be utilised in most of the industrial processes, even in the high-temperature ones. When an RTD is made with the metals like platinum, these become highly stable, and then they aren’t damaged much by oxidation/corrosion. Other materials including copper, nickel-iron alloy, or just nickel too could be utilised for RTDs. But such materials aren’t used generally as they are having low temperature ability, and they aren’t quite stable also or have repeatable capability as that is there in platinum. So, RTDs provide many benefits, some of which are as follows:
  • Lengthy stability
  • Nice interchangeability
  • Fine accuracy (even better than a thermocouple)
  • Vast temperature range (from around -200 degree Celsius to 850 degrees Celsius)

Liquid’s Temperature Measurement Using an RTD

Sensors that are probe-type are most commonly utilised to measure liquids. These could be quite simple ones having connection heads along with transmitters. Out of these, a widely popular sensor is the quick-disconnect one. It could be utilised as is, with compression fitting for installing flexibly. While doing the measurement of temperature in very harsh environmental conditions like that in plating baths or like in high-pressure systems, these sensors could be covered materials such as PFA Teflon® or contained in a protective housing of thermowell for protecting it against any harsh conditions.

Measuring Air & Gas Temperatures Using RTD Sensors

Measuring air & gas flow is quite a challenge in itself as the rate at which temperature transfers from liquids to sensors tends to be quite slow in the case of liquids. This is why, sensors especially made to be used in air/gas place the sensing element in close proximity to the environment. Such sensors tend to allow the sensing element to be in almost direct contact with the air flow. Such a design is quite popular for measuring temperature of the air in labs, clean rooms, & other such places because the housing design includes elements, which allow air to flow past the element. If such a situation needs some more protection for the sensors, an alternative is to utilise a structure quite like the RTD-860. Such a model has a small-diameter sensor having a mounting flange. The set reacts a little slower to alterations in the air flow, however, it provides better protection for the sensors.

Measuring Surface Temperatures

Measuring surface temperature could possibly be a very intricate thing to do properly & accurately. There’re several styles to make the selection, as per how anyone wishes to mount the sensors, how sensitive the sensor should be to any temperature alterations, and whether or not the installation would be permanent. Some of these are quite speedy & highly accurate responding surface RTDs

RTD Glossary

  • RTD: RTD is the abbreviation for resistance-temperature-detector/device. These indicators work on the principle that the electrical resistance of the conductor alters with the temperature.  
  • RTD Element: Part of an RTD sensor that could be built mostly of nickel, platinum, or copper material. 
  • RTD Probe: This happens to be an assembly consisting of an element, a sheath or housing, a wire & a terminal/connection. 
  • Platinum RTDs: Even called Pt RTDs, these are usually the most linear, most stable, most repeatable and highly accurate of all of the other RTDs. 
  • Thin Film RTD: These consist of a thin layer of base metal, which has been embedded in a ceramic substrate & cut for achieving the wished resistance. 
  • Class A RTD: Highest tolerance & accuracy of RTD elements, Class A (IEC-751), alpha = 0.00385 
  • Class B RTD: The most common of the RTD element tolerance & accuracy, Class B (IEC-751), alpha = 0.00385 
  • Aplha .00385 curve: The European curve corresponds to the tolerance of the “0.1% DIN” standard & conforms to the DIN 3760-standard. 
  • Sheath: The casing, a tube with a closed end, secures the element, and protects it against moisture & the medium to be measured. This also gives protection as well as stability to the transition wires from the sensitive element wires.

Thermocouples

About the Seebeck Effect

How Do Thermocouples Work?

Types of Thermocouples

What’s the Response Time of Thermocouples?

How to Choose the Most Ideal Junction Type?

Choosing the Most Apt Thermocouple

How to select between thermocouples, RTDs, thermistors & infrared devices?

 

What Are Thermocouples? Introducing the Concept of Temperature Measurement

Thermocouples are basically the sensors used to measure temperature. These sensors consist of 2 different metal wires, which have been linked at one of the ends & connected to the thermometer of the thermocouple or other device that is thermocouple-capable at the other end. When it’s properly configured, a thermocouple could possibly assist in providing accurate temperature measurement over a vast temperature range. A thermocouple is known for its versatility as a temperature sensor so generally utilised over numerous applications, from industrial usages to regular utilities & appliances. Owing to its vast range of models & specifications (technical), it’s highly significant to figure out its basic structuring, how it works, the range as to better decide which is the right type of thermocouple & the right type of thermocouple material for your specific application.

 

About the Seebeck Effect

In the year 1821, Thomas Seebeck, who was a German physicist, had discovered the constant current flow inside the thermoelectric circuits when 2 wires of non-similar metals are conjoined at both the ends & one of those ends is heated.

 

How Do Thermocouples Work?

When 2 wires consisting of different metals tend to be connected at both the ends & 1 end is heated, there’s a constant current that flows inside the thermoelectric circuits. If such circuits tend to get broken towards the centre, the Seebeck-voltage, which is the net-open-circuit’s voltage, happens to be a function of the junction’s temperature & the composition of those 2 metals. This tends to imply that when such a junction of 2 metals is either heated or cooled, a voltage tends to be released that could be correlated back to that particular temperature.

 

Types of Thermocouples

Thermocouples tend to be available in varied combinations of metals/calibrations. The most common of them are the “Base-Metal-Thermocouples,” which are called a Type J, Type K, Type T, Type E & Type N. There are even high temperature calibrations, called as “Noble-Metal-Thermocouples,” which are Type R, Type S, Type & Type GB. All of these calibrations tend to have different temperature ranges as well as different environments, though the maximum temperature tends to vary with the wire’s diameter, this is the wire that is utilised inside the thermocouple. Though the thermocouple’s calibration commands the range of the temperature, still the maximum temperature range is even limited by the thermocouple wire’s diameter. This shows that a quite thin thermocouple might not reach the full range of temperature. Type K thermocouples tend to be known for general purposes owing to their low cost & their temperature range.

 

Choosing Thermocouples

  1. First and foremost, try to determine your application where you would utilize the thermocouple.
  2. Then, analyze the ranges of temperatures to which your thermocouple would get exposed to.
  3. Also, consider any of the chemical resistances required for your thermocouple/sheath material.
  4. After that, evaluate your need for abrasion & vibration resistance.
  5. Lastly, list any of the installation needs.

 

Choosing the Type of Thermocouple

As thermocouples measure in vast ranges of temperatures & could be relatively rugged, therefore these have quite frequently industry usages. The criteria given below are used while choosing the right thermocouple:

  • Temperature ranges
  • Thermocouple’s chemical resistance or sheath material
  • Abrasion resistance & vibration resistance
  • Installation needs 

 

What’s the Response Time of Thermocouples?

A time-constant tends to be expressed as that time, which is required by the sensor for reaching 63.2 percent value of a step-change in that temperature under the mentioned conditions. 5-time constants tend to be needed for the sensor for approaching a 100 percent value of the step-change. The exposed-junction-thermocouple tends to provide the speediest response. Additionally, the smaller is the diameter of the probe sheath, the speedier is the response, but the maximum temperature might be lesser. Also, one needs to be aware of the fact that the probe sheath sometimes can’t withstand the full range of temperature of the thermocouple’s type. 

 

How to Choose the Most Ideal Junction Type?

The probes of sheathed thermocouple tend to be available with 1 of the 3 junction types, which are as follows:

  1. Grounded
  2. Ungrounded 
  3. Exposed

Right at grounded one’s tip, the wires of the thermocouple tend to be attached physically towards the inside of the wall of that probe, which leads to proper heat transfer from the outside, via the probe’s wall to the thermocouple’s junction. In the ungrounded one, the junction gets disengaged from the wall, & also the response time tends to be slower than that of the grounded one, but the ungrounded one tends to provide electrical isolation.

Heatcon Sensors happens to be the one-stop-source for all these requirements. With worthy products, effective process measurement and good process control, Heatcon provides you with the best shopping experience for procuring the best-in-class Thermocouples. 

 

Choosing the Most Apt Thermocouple

  • Beaded-Wire Thermocouples: Beaded-wire thermocouples happen to be the simplest thermocouples. They contain 2 pieces of thermocouple wires, which are connected by a welded bead. Now, as these thermocouple beads are exposed, the applications have many limitations. These thermocouples mustn’t be utilised with liquids, which may corrode/oxidize the thermocouple compounds/alloys. Metal surfaces could even be problematic. Metal surfaces, especially pipes, are often utilized for grounding the electrical systems. Indirect connections to the electrical systems can affect measurement of the thermocouples. Generally, such a type of thermocouple happens to be a nice selection for measuring gas temperature. Because it could be very small, it offers quite speedy response times. 
  • Thermocouple Probes: Thermocouple probes consist of a thermocouple-wire that is placed inside the metal tube. The tube wall is called the probe’s sheath. The most common sheath material is stainless steel & Inconel®, which happen to support much higher ranges of temperatures than that of stainless steel, but stainless steel is usually preferred owing to its broader chemical compatibility. Some other more exotic materials for sheaths are available for quite a higher range of temperatures. The thermocouple probe tip is usually available in 3 varying styles, which are grounded, ungrounded & exposed. With the grounded end or tip, the thermocouple remains in contact with the wall of the sheath. The ground one gives faster response time, however it’s quite sensitive to electric ground loops. In the ungrounded junction, thermocouples tend to be separated from the wall of the sheath by an insulating layer. The end or tip of the thermocouples extends outside the wall of the sheath with an exposed junction. These happen to be ideal for measuring air. 
  • Surface Probes: Measuring the temperatures of solid surfaces happens to be tough for many sorts of temperature sensors. For ensuring accurate measurements, the total measuring region of ​​the sensors should be in contact with its surface. This becomes tough while working with rigid sensors & surfaces. As a thermocouple is made of flexible/pliable metals, the junction could be made flat & thin for ensuring maximum contact with rigid solid surfaces. Such a thermocouples is a great selection for measuring the surfaces. Thermocouples could also be turned into rotating mechanisms, so that they become ideal for the measurement of temperature of moving surfaces. 
  • Wireless Thermocouple: Wireless Bluetooth transmitter connects to the smartphones/tables for recording, logging, tracking, measuring & monitoring the temperatures. Such a transmitter measures a variety of sensor inputs to include, but not limit to, temperatures, pH values, RTDs, & relative humidity. Data transfer takes place via wireless Bluetooth technology to smartphone devices or tablets, on which the applications are installed. These applications allow the smartphones to pair & configure multiple transmitters.

FAQs

  • What is the accuracy level & temperature measuring ranges of different types of thermocouples? For knowing about the accuracies & temperature ranges of different types of thermocouples, there is a thermocouple colour coding. It’s significant to recall that both of the accuracy & the carrying capacity depends on some aspects including the alloys of the thermocouples, the measured temperatures, the structuring of the sensors, the sheath materials, the substances that are to be measured, the state of the environment (liquid or solid or gaseous) and the thermocouple-wire’s diameter (if exposed) or the sheath’s diameter (if the wire of the thermocouple isn’t really exposed but sheathed). 
  • Which one should be used; grounded probe or ungrounded one? This largely depends upon the instruments. If it’s possible that there is a reference to the ground (usually seen in controllers commonly with non-isolating inputs), in that case, ungrounded probes would be needed. If the instruments are portable or handheld meters, in those cases, grounded probes would be preferred. 
  • Can multimeters be used to measure temperature using a thermocouple? Thermoelectric voltage overall magnitude largely depends upon the closed (detecting) & open (measuring) ends of the wires of a given thermocouples’ assemblies with alloy leads. Temperature sensors using thermocouples consider the temperature of the measuring side for determining the temperature of the sensing side. Many of the millivolt meters don’t have such a feature, nor they have the non-linear scaling capability for converting the measurement of millivolt into a value of the temperature. Lookup tables can be used to fix a given military voltage reading & calculate the temperature that is being sensed. But the corrected value should be constantly recalculated because it’s usually not constant all the time. Small temperature alterations in the measuring devices & heads would alter this correction value.  

How to select between thermocouples, RTDs, thermistors & infrared devices?

You must acknowledge the capabilities, features & prices of different sensors, along with their existing instruments. Additionally, thermocouples could usually help in measuring temperatures over wide ranges, and also, they are inexpensive & quite durable, but these are not as accurate/stable as Resistance-Temperature-Detectors (RTDs) & thermistors. Resistance-Temperature-Detectors are fairly more stable & they also have a quite wide range of temperature measurement, but these aren’t as durable & inexpensive as the thermocouples are. Now, as they need the utilization of electrical current to measure, RTDs could be prone to errors due to self-heating. Thermistors, on the other hand, are generally more accurate than RTDs/thermocouples but these tend to have a more limited range of temperature measurements. These are also prone to self-heating. An infrared sensor could be utilised for measuring temperatures, which tend to be higher than any other device that too without any direct contacts with the measured surfaces. But these are usually not as accurate and sensitive to the surface-radiation-efficiency (surface-emissivity). Using fibre optic cables, these could help in measuring surfaces, which aren’t in the direct line of sight.

 

 

2 Ways of Using Thermocouple to Measure Temperature in an Industrial Setting!

Optimized for Simplicity & Cost-Effectiveness

Optimized for Accuracy & Flexibility

Using Thermocouple to Measure Temperature

Practically Putting Thermocouples to Measure Temperature

Thermocouples are widely used temperature sensors due to their simplicity, durability, and wide temperature range capabilities. They consist of two dissimilar metal wires that generate a voltage proportional to the temperature difference between their measuring and reference junctions. This voltage can be measured and converted into temperature readings, making thermocouples a valuable tool in various industries, including manufacturing, automotive, aerospace, and scientific research. 

Using Thermocouple to Measure Temperature: 2 Different Means of Measurement

Let us explore two different means of using thermocouple to measure temperature: one optimized for simplicity and another optimized for accuracy & flexibility.

#1: Optimized for Simplicity & Cost-Effectiveness

When it comes to simple temperature measurements, thermocouples offer a straightforward & cost-effective solution. The setup typically involves a thermocouple probe, extension wires, and a temperature indicator or data acquisition system. Here’s a step-by-step guide to practically implementing this measurement solution while using thermocouple to measure temperature:

  • Select the appropriate thermocouple type: Thermocouples are available in various types, including Type K, Type J, Type T, and Type E, each with different temperature ranges and sensitivities. Choose the thermocouple type that suits your specific application requirements.
  • Prepare the thermocouple probe: The thermocouple probe is the part of the sensor that comes into direct contact with the object or medium being measured. Ensure that the probe is clean and free from any contaminants that could affect the temperature reading.
  • Connect the extension wires: Extension wires are used to connect the thermocouple probe to the temperature indicator or data acquisition system. Use extension wires made from the same thermocouple materials to maintain accuracy. Keep the wire length as short as possible to minimize signal degradation.
  • Reference junction compensation: The reference junction is the point where the thermocouple wires connect to the temperature indicator or data acquisition system. Since the reference junction is typically at a different temperature than the measurement point, it is crucial to compensate for this difference. This can be achieved by using a reference junction compensation method, such as a built-in cold junction compensator or an external reference junction temperature sensor.
  • Calibration and accuracy verification: To ensure accurate temperature measurements, it is essential to calibrate the thermocouple system periodically. This involves comparing the readings from the thermocouple with a known temperature reference source. Calibration can be performed using certified temperature standards or calibration equipment.

#2: Optimized for Accuracy & Flexibility

While the first measurement solution provides simplicity & cost-effectiveness, certain applications require higher accuracy & greater flexibility in temperature measurements. Here’s a more advanced approach for optimizing accuracy & flexibility while using thermocouple to measure temperature:

  • Use a thermocouple data logger: A thermocouple data logger is a device that combines the functions of a temperature indicator and a data acquisition system. It allows for continuous temperature monitoring and logging over extended periods. Look for a data logger that supports the specific thermocouple type and temperature range you require.
  • Implement multiple thermocouples: By employing multiple thermocouples, you can monitor temperature variations at different points simultaneously. This technique is particularly useful in applications where temperature gradients or spatial variations need to be analysed.
  • Consider thermocouple amplifiers: Thermocouple amplifiers amplify the small voltage signals generated by thermocouples, reducing noise, and improving measurement accuracy. These amplifiers can be integrated into the data acquisition system or used as standalone modules.
  • Implement cold junction compensation techniques: Compensating for the temperature difference between the reference junction and the measurement point is crucial for accuracy. Utilize advanced cold junction compensation techniques such as isothermal blocks, thermoelectric coolers, or active compensation circuits to achieve highly accurate temperature measurements.
  • Perform system validation: Regular system validation is vital to ensure accuracy & reliability. Validate the thermocouple measurement system by comparing its readings with other calibrated temperature sensors or traceable temperature references.

Using Thermocouple to Measure Temperature

So, using thermocouple to measure temperature has great industrial relevance as thermocouples provide a versatile & practical means of measuring temperature in a wide range of applications. By following the guidelines mentioned above, you can implement thermocouple-based temperature measurement solutions optimized for simplicity, accuracy, and flexibility. Whether you require a straightforward temperature reading or advanced monitoring capabilities, thermocouples offer a reliable and cost-effective solution. Always remember to consult the thermocouple manufacturer’s guidelines and best practices for your specific application to maximize accuracy and performance.

Thermocouple: An Economical & Accurate Means to Measure Temperature 

Temperature measurement is crucial in various industries and applications, ranging from industrial processes to scientific research. Among the different temperature measurement devices available, thermocouples stand out as a reliable and cost-effective solution. 

What are Thermocouples?

Thermocouples are temperature sensors that generate a voltage proportional to the temperature difference between their two junctions. They are made of two dissimilar metal wires, joined together at one end, known as the hot or measurement junction, while the other end remains unconnected, forming the reference or cold junction. When there is a temperature gradient between the hot and cold junctions, a thermoelectric effect is produced, resulting in the generation of a small voltage.

Great Use of Thermocouples in Everyday Life in Temperature Measurement

Here’s the detail about the great use of Thermocouples in everyday life for different temperature measurement requirements. 

  • Wide Temperature Range: Thermocouples can measure temperatures from extremely low (cryogenic) to extremely high (up to 2,300°C or higher) ranges. This versatility makes them suitable for various industrial applications and scientific research.
  • Quick Response Time: Thermocouples offer a rapid response to temperature changes, making them ideal for dynamic processes that require real-time temperature monitoring and control.
  • Robustness: Thermocouples are highly durable and can withstand harsh environments, including high pressures, corrosive atmospheres, and mechanical vibrations. This robustness makes them suitable for challenging industrial settings.
  • Cost-Effective: Thermocouples are relatively inexpensive compared to other temperature measurement devices, such as resistance temperature detectors (RTDs) or thermistors. This cost-effectiveness makes them a popular choice, especially in applications requiring multiple temperature sensors.

Fundamentals of Thermocouples

  • Seebeck Effect: The Seebeck effect is the underlying principle behind the functioning of thermocouples. It states that when two dissimilar metals are connected and exposed to a temperature gradient, a voltage is generated across the junctions, which happens to be in direct proportion to the difference in the temperatures.
  • Thermoelectric Circuit: A thermocouple forms a thermoelectric circuit consisting of two dissimilar metal wires. The metals used and their combinations determine the thermocouple type, such as Type K, Type J, or Type T. Each type has specific temperature ranges and characteristics.

Potential Issues with Thermocouples

While thermocouples are reliable, a few problems can arise, some of which are given underneath:

  • Damage to Parts: Sheaths, protection tubes, & also thermowells, could possibly tend to fail owing to the damage done by corrosion or due to any mechanical damages.
  • Temperature Issues: The processes could possibly go over temperature, which can then expose thermoelements to temperatures higher than the anticipated limits.
  • Measurement Inaccuracies: Environmental factors, such as electromagnetic interference or poor electrical connections, can cause measurement inaccuracies. Calibration drift over time is also a concern.
  • Cold Junction Compensation: The reference or cold junction must be maintained at a known temperature to ensure accurate measurements. Failure to compensate for the cold junction temperature can lead to errors.
  • Thermocouple Breaks: Physical damage to the thermocouple wires or junctions can cause open circuits and result in incorrect temperature readings.
  • Human Errors: Human errors could also be the causative factors. Controls might be set incorrectly; connections might be made imperfectly, & actions might be inappropriate for the operating conditions could possibly be inadvertently applied. Instrument pooling along with training & accountability are common ways to combat such mistakes.

 

Troubleshooting Thermocouple Issues

  • Check Connections: Ensure that the thermocouple connections are secure and free from corrosion or loose contacts.
  • Calibrate Regularly: Periodic calibration against a known temperature source helps identify and correct any calibration drift or inaccuracies.
  • Cold Junction Compensation: Use a cold junction compensator, such as a thermocouple reference table or a dedicated temperature transmitter, to accurately compensate for the cold junction temperature.

Testing a Used Thermocouple

  • Visual Inspection: Examine the thermocouple for physical damage, such as broken wires, loose connections, or signs of wear and tear.
  • System Tests: Connect the thermocouple to a known temperature source and compare the displayed temperature with the reference value. 

How to Test a Used Thermocouple Using System Tests?

Testing a used thermocouple using system tests involves verifying its functionality and accuracy within a temperature measurement system. Here are the steps to perform a system test:

  • Gather Required Equipment: You will need the following equipment for testing:
    • Known Temperature Source: This can be a calibrated reference thermometer or a temperature chamber with a known temperature.
    • Portable Temperature Indicator: This happens to be quite a useful tool for troubleshooting thermocouple systems. It can work with 2 or more varied types of thermocouples, and some offer an “output” feature that produces an electrical output for simulating the thermocouple operating at a certain temperature(s).

Understanding Thermocouples

Thermocouples are temperature sensors that generate electrical voltage proportional to the temperature difference between their junctions. They rely on the Seebeck effect, where two dissimilar metals joined together at their ends produce a measurable voltage when exposed to temperature variations. This voltage can be measured and used to accurately determine the temperature.

Principles of Operation

Thermocouples in space are typically composed of two different metal wires, known as thermoelements. Common thermocouple types used in space missions include Type K, Type J, and Type T. These thermoelements are connected at one end to form the measurement junction and extend to the termination junction, which is maintained at a known reference temperature. The temperature difference between the measurement junction and the termination junction generates a voltage that is read by instruments on board the spacecraft.

Thermocouples in Space

Managing temperature is critical in the space segment, and thermocouples in space happen to be the essential tools in this field. Such thermocouples have been designed in such a way that they are used for systems on board satellites as well as space probes. Applications tend to include temperature control of the chemical propulsion catalyst bed and the temperature of particular ISS science test programs. These are even suited for using in the skin measurements for re-entry & special rakes for gas flow measurement in the launch vehicles. Such thermocouples have been usually installed in spacecraft engines for regulating the system temperature as well as for recording & monitoring system temperature behaviour. Thermocouple wires are available in several different diameters, that too with alternative outer sheaths depending upon the range of temperatures.

Multi-location measurement of temperatures is quite usual in the process of automotive testing. For the measurement of thermocouples in the brakes, the wire bundle of the thermocouple could speedily attain a stage wherein the diameter starts impacting the structural integrity.

Disk Temperature & Brake Block Measurement

Temperature of the disk surface directly tends to affect the braking performance, & thus, temperature measuring systems tend to be significant in developing effective braking systems and for continuously monitoring the final product. The measuring systems have to record extremely variable temperature ranges occurring on the brake discs & pads. Usually, thermocouples tend to be fixed in the brake disk(s) & within the brake pad(s), as well as collector rings that tend to be integrated inside the circuit. Optical measuring systems like pyrometers, thermal cameras, & thermal scanners tend to be also utilised in the process of brake testing. The surface pressure distribution inside the brake pad(s) could even be revealed with the help of thermocouple system(s).

Measurement of Racing Cars’ Disk Brake Callipers

Temperature extremes could possibly change the brakes’ crystal structuring of the disk surface & also lead to crack the damage done to the surface. The deflection of the brake disk considerably affects the comfort of the brakes as the driver feels, because it’s transported into the steering-wheel as well as the brake system. Likewise, the friction(µ) coefficient of the alterations while the temperatures change lead to brake torque variations (also called as fading). Therefore, sound knowledge of the temperature gradient inside the brake disk as well as the brake pad is crucial.

Measuring Exhaust Gas Temperature

Turbocharger happens to be the significant element of the modern engine. It has superior rotational speed & comes in various shapes as well as sizes, and therefore, turbo chargers now happen to be complex subsystems in themselves. This is crucial for shielding the turbo from extreme temperatures during its service life because it’s generally exposed to supreme temperature exhaust stream. The temperature sensor with a speedy response happens to be a vital component of the control loop.

Measuring Temperature on the Simulated Exhaust

In automotive testing, manufacturers are required to test all the elements to their limits which they may encounter during the shelf life of any automobile. A large number of polymer elements tend to be found inside the modern automobile vehicles & they need to be subjected to several tests including the heat stress testing in case of they are being in close proximity to any heat source. For example, the bumper happens to be situated next to the engine’s exhaust gas system, wherein, the temperatures can attain quite extreme highs. So, the material of the bumper needs to be tested to ensure that it does not affect the increased temperature adversely of the exhaust, which may lead to polymer’s thermal degradation or even a fire (in a worst-case-scenario). In such state-of-the-art testing processes, the exhaust system tends to be subjected to simulated heat from a custom-made electrical heater, therefore escaping the utilization of the car engine.

Thermographic Pyrometry & Infrared Pyrometry 

The utilisation of infrared pyrometry & thermographic pyrometry for analysing heat distribution in the engines of the cars tends to be highly convenient for temperature measurements (that are non-contact) to test automotive engines and during any common inspection application.

Oven Temperature’s Profiling System

Automotive painting & automotive coating depends largely on the significant controlling of the temperatures so that it obtains the best paint finish in the material’s curing operation.

Optimization of Air Conditioning 

Air conditioning is quite significant inside the modern vehicles; there’re efficiency needs for satisfying, and also regulations by the government.

Temperature Sensors

Temperature sensors are electronic devices that measure and monitor the temperature of various objects and environments. They play a vital role in a variety of industries, including HVAC, food processing, automotive, healthcare, and aerospace. 

Cost of Temperature Sensors 

Buyers’ biggest concern seems to be the price front, as most of them assume that all types of temperature sensors cost the same, which is not the case! This is because all industrial applications of temperature sensors are not the same, so all temperature sensors cannot be created as equal, therefore their prices tend to vary. The prices of RTDs & thermocouples are largely determined by different factors, like the applications for which they might be used for as well as the temperatures at which they will be operating. For example, the temperature sensors which measure the air temperature in a particular room would vary from the one that is utilised for measuring 1400 degree Celsius in an industrial heat treatment process. It all means that getting the right tool for the job is important!

Factors Directing the Cost of Temperature Sensors

The cost of temperature sensors can vary greatly, depending on several factors, as explained below:

  • Market Application: One of the most significant factors driving the cost of temperature sensors is the market application. Sensors used in high-end applications such as aerospace and medical equipment have higher accuracy, precision, and reliability requirements, which drives up the cost. Sensors used in less critical applications, such as household appliances or automotive engines, may have lower accuracy and precision requirements, resulting in lowering the costs.
  • Temperature Measuring Range: Temperature sensors are designed to measure temperatures within specific ranges. The wider the temperature measurement range, the more complex the sensor construction needs to be, which increases the cost. For example, a sensor designed to measure temperatures from -40°C to 125°C will be more expensive than a sensor that measures temperatures from 0°C to 50°C.
  • Hazardous Locations: Sensors used in hazardous locations, such as petrochemical plants, must meet specific safety requirements. They need to be explosion-proof, intrinsically safe, or have other protective measures to prevent accidents. This additional safety equipment adds to the overall cost of the sensor.
  • Construction of the Sensors: The cost of temperature sensors also depends on the sensor’s construction. Some sensors are designed to be small & lightweight, while others are intended to be durable and withstand harsh environments. The type of materials used to construct the sensor, such as stainless steel or plastics, can also affect the cost.
  • Options & Accessories: The cost of temperature sensors can vary based on the additional options and accessories that come with them. For example, sensors with wireless connectivity, calibration certificates, or custom-designed probe configurations can be more expensive than basic models.

Selecting the Right Thermocouple

Guide to Use a Thermocouple

Here’s a quick guide to use a thermocouple. First and foremost, it is important to know what a thermocouple is and for what application you need it! By knowing the application, you can start using the thermocouple in the correct way. 

About Thermocouple Sensors

Thermocouple sensors are the tools utilised for measuring temperatures; they use 2 different types of metal wires. These are connected at 1 of the ends & are connected to the thermocouple’s thermometer at the other. The thermocouple sensor along with the thermometer allows us to send signals to each other; and, if configured correctly, can provide accurate temperature measurement(s). The temperature range is quite wide and can reach up to 1250 degree Celsius. This surely depends on what sort of thermocouple being used, some do not even reach that particular range & some could also detect boiling temperatures below -200 degree Celsius. Thermocouple sensors are useful in instant temperature detection. They’re even known for versatility as they’re quite commonly used in many applications. They’re even available in various types of models. It’s also quite significant to understand that each model type has its own basic structure and how the devices work. You need to choose the right type of thermocouple sensor that is most suitable for your application.

Types of Thermocouples 

  1. Beaded Wire Thermocouple: This happens to be one of the simplest forms of thermocouples. This has 2 thermocouple wires that are connected through a welded bead. That’s the reason why it’s called a wire-thermocouple. Though the thermocouple’s welded bead tends to be exposed, still it’s limited to only a few applications. Do not use this beaded thermocouple in a liquid environment or immerse it in liquid, as it can corrode/oxidize the thermocouple’s compound. Making use of metal surfaces can sometimes be difficult. Often, metal surfaces used in ground power systems have a non-direct connection with the power system, which can affect thermocouple’s measurements. In other words, such thermocouples are ideal for gas temperature measurement. The reason being their smaller size and faster response time.  
  2. Thermocouple Sensor: These work by placing a thermocouple wire inside a metal tube. This tube is known as the sheath. The probe sheath is constructed out of standard stainless steel & Inconel®, which supports higher temperatures than stainless steel. However, stainless steel is generally preferred over Inconel due to its broader chemical compatibility. If very high temperatures are involved, other exotic shell materials are even available. The only thing different is the tip of the thermocouple probe. 
  3. Surface Probe: The most difficult part of thermocouples is the measurement of a solid surface. Most temperature sensors cannot perform this task. So, to get an accurate measurement, the entire measuring area must be connected to the surface. Rigid sensors & rigid surfaces are difficult to work with. Such types of thermocouples are ideal for surface measurement because they can even be built into a rotary mechanism.

How Does It Work?

When 2 conductors are made of different metals, with 1 of the ends connected, & when heated, a constant current flows in the thermoelectric circuit. Now, if the said circuit somehow gets broken towards the middle of it, then the open-circuit-voltage (which is the Seebeck-voltage) happens to be a function of the junction’s temperature & lies among the 2 metal compounds. So, this means that when the junction of two metals is heated or cooled, a voltage is created that can be inversely correlated with temperature. The measurement works like this. 

Other Categorizations of Thermocouples 

There are several characteristics as well as different varieties of thermocouples, each of these types tend to have different characteristics. They are also having different combinations of metals and/or calibration(s). The most common are “base-metal-thermocouples.” The most common types are N, T, E, E J & K. In addition, there’re also high temperature calibrations, also known as “Noble-Metal-Thermocouples,” which happen to be types R, S, C and GB. Various sorts of thermocouples have distinct calibration ranges as well as varied metal combinations/alloys. Each of these fittings tend to have different temperatures as well as environment. The max temperature can vary depending on the wire diameter used in the thermocouple. Even though the calibration tends to determine the temperature-range, the max-temp range is limited as well. This is due to the diameter of the thermocouple wire. The finer the thermocouple wire, the lower the chance of reaching the entire temperature evenly. A K-type thermocouple is known as a general-thermocouple.

Selecting the Right Thermocouple

There are 3 different styles in toto, which are ungrounded, grounded, & exposed. 

  1. The grounded end of the thermocouple contacts the enclosure wall, which when in place, provides a faster response time, and is most sensitive to electrical ground loops. 
  2. For an ungrounded connection, the thermocouples are separated from the sheath’s walls by insulating layers. 
  3. The thermocouple’s end extends outside the enclosure wall with an open junction. These open junction thermocouples are best suited for measuring air.

Air Temperature Indicator in Aircraft

Air Temperature Indicator in Aircraft

Non-Electrical Temperature Sensors

Air Temperature Indicator in Aircraft

The temperatures of many objects should be known prior to the flight for the correct operation of an aircraft. Such equipment acts as the air temperature indicator in aircraft! These aircraft temperature measuring equipment include the intake air, engine oil, free air, carburetor mixture, engine’s cylinder heads, heater duct as well as turbine engine exhaust  temperature. These happen to be all the things that require proper monitoring of temperatures. Several other temperature measurements should be known as well. Various thermometers are being utilized for collecting & displaying temperature data. 

Non-Electrical Temperature Sensors 

The physical properties of many of the materials alter when they are exposed to any alterations in the temperatures. These alterations tend to be continuous, for example, the expansion/contraction of solids, liquids, & gasses. The coefficient of such an expansion happening with various materials tends to be different, and is individual for every such material. 

  • Many people are quite familiar with the liquefied mercury thermometer most of us use at home. As mercury increases in temperature, it expands and goes up along a narrow channel with a scale that can be utilized for reading the temperature associated with that expansion. Such mercury thermometers are of no use at all in the aviation industry.
  • Bimetallic thermometers, on the other hand, are quite useful in the aviation field. The element used for sensing the temperature measurement of such bimetallic thermometers is made of 2 different metal strips that are glued together. Every metal tends to expand as well as contract at different rates as the changes in temperature happen. 1 of the ends of this bimetallic strip tends to be fixed, while the other end is twisted. A pointer is attached to the threaded end, which is inserted into the body of the instrument. When the bimetallic strip gets heated, the 2 metals tend to expand. Because they have different expansion rates, and are connected to each other; the coiled end will try to loosen if one metal expands faster than the other. This leads to a movement in the pointer over the instrument dial. As the temperature tends to drop, the metals tend to contract at different rates; this tightens the coil & helps in the movement of the pointer in the opposite direction.
  • Direct-range bimetallic temperature gauges have been in use much frequently in light aircraft for measuring free air temperatures or the outside air temperatures (OAT). In such an application, the collection probe is inserted through the aircraft’s windshield for exposing it to atmospheric air. The end that is coiled on the gauge head’s bimetallic strip is just inside the windshield where the pilot can read it.
  • The bourdon tube too is utilized for direct reading non-electrical temperature gauges for simple & light aircraft. Bourdon tube gauge’s dial face with temperature scale tends to be the indicator of the temperature. Such an operation is based on the uniform expansion of the steam that has been generated by the volatile liquid present in a closed space. Such pressure from the vapor varies with temperature directly. By filling a sensing bulb with this type of volatile liquid and then connecting it to a Bourdon tube, it helps in acting as an indicator of the rise & fall of the vapor pressure owing to the changes happening in the temperature. Calibrating the handle in degrees (Fahrenheit/Celsius) instead of psi gives a reading of the temperature. In this type of meter, a sensor bulb tends to be placed in the region where the temperature is being measured. A lengthy capillary tube tends to connect the bulb to a Bourdon tube in the instrument’s housing. The capillary tube’s much narrower diameter ensures that the evaporating liquid is light and it also remains mainly in the sensor bulb. Sometimes oil temperature is also measured like this.

Utilizing electricity to measure different temperatures is quite prevalent in the aviation industry. Different ranges of temperature tend to be measured in a more suitable way by one or the other sort of the system. Below mentioned are some measuring systems as well as indication systems that are largely seen in various sorts of aircraft. 

Electrical-Resistance Thermometers

The main parts of electrical-resistance thermometers happen to be the indicator instrument, the element (or the bulb) that is temperature-sensitive & the connecting wires along with the plug connectors. Such type of a thermometer is largely used in various types of aircraft for measuring carburetor air, oil, free-air temperature etc. These are utilized for measuring low & medium temperatures between -70 degree Celsius and 150 degree Celsius. 

The electrical resistance of most metals alters when the temperatures of those metals tend to change. A resistance thermometer works on this principle. Normally, the electrical resistance of metals tends to augment with increasing temperatures. Different metal alloys tend to have high temperature-tolerance coefficient, which means that their resistance differs significantly with temperatures. This property makes them highly suitable to be used in devices used for sensing temperatures. The metal resistors are in contact with the liquid or the area where the temperatures are to be measured. This is wired to a device in the cockpit detector. Optionally, the instrument dial tends to be calibrated in degrees Celsius or degrees Fahrenheit instead of ohms. As the measured temperature tends to change, the metal resistance also changes, and the indicator shows the exact extent to which the change is happening.

A common electrical-resistance thermometer appears to be like any other such thermometer. For use in multi-engine aircraft, these detectors are available in 2 different forms. Most such indicators themselves compensate for cabin temperatures. A thermally-sensitive resistor is designed to have its own resistance for every temperature value within its operating range. The temp-sensitive resistive element happens to be the length or coil made of nickel or manganese wire or any other such suitable insulating material alloy. The resistor tends to be protected by a sealed metal tube that is connected to a hexagonal head. The 2 ends of the coil are soldered or welded to a socket designed to accept the plugs of the plug connector. 

Such indicators include the resistance measuring devices. They sometimes use a modified form of the Wheatstone Bridge circuit that works on the principle of balancing 1 unknown resistance with other such known resistances. 3 resistance values ​​of the same are connected in a bridge circuit that is diamond-shaped. One resistor, whose value is unknown, also happens to be one part of the circuit. The unknown resistance shows the temperature bulb’s resistance of the electric-resistance thermometer system. A galvanometer is fixed at 2 points in the circuit. 

If the temperature makes the resistance of the bulb the same as the other resistances, there’s no potential difference between the 2 points in the circuit. So, no current will flow in the galvanometer’s leg of the circuit. As the temperature of the bulb changes, so does its resistance, and the bridge tends to become imbalanced, leading to the current to flow through the galvanometer in 1 direction or the other. The pointer of a galvanometer is basically the pointer of a gauge. The time of it moving against that dial-face that is calibrated in degrees, the temperature is shown. Many such pointers are equipped with a zero adjustment screw on the front of the instrument. This adjusts the tension of the pointer reset spring when the bridge is at the balancing point (this happens to be that position where the bridge circuit tends to balance & no current flows through that meter).

One more method to determine the temperatures using electrical-resistance thermometers is to do it by utilizing a ratiometer. In the Wheatstone bridge detectors, there are failures due to fluctuations in the mains voltage. The ratiometers tend to be more stable, & they can provide much larger accuracy. As suggested by their name, ratiometer electrical-resistance thermometers help in measuring the ratio of current. 

The sensor part of the resistance bulb of such types of thermometers is primarily similar to the one explained above. The circuit consists of a variable resistance as well as a fixed resistance to give the reading. This consists of 2 power supplies; each having a coil that is mounted on one of the sides of that pointer mounted in the field of a large-sized permanent magnet. The changing current passing through the coils leads to varied fields reacting with the much larger permanent magnet’s field. Such an interaction turns the cursor against a dial that has been calibrated in degrees Fahrenheit/Celsius, providing the indication of the temperature being measured. 

The ends of the magnetic poles of such types of permanent magnets tend to be closer at the topmost point than at the bottom-point. It leads to the flux’s magnetic field lines among the poles to concentrate at the tip. When the 2 coils release their own magnetic field, the one that is stronger tends to interact & deflect down into the weaker one, which happens to be the less concentrated part of the permanent field of the magnet; however, the field of the weaker coils moves up into the more concentrated large magnet’s flux field. This leads to a sort of balancing effect, which alters but tends to remain balanced as the coil field becomes strengthened and varies with the temperatures & currents that are flowing in the coils. 

For instance, if the temp-bulb’s resistance is the same as the value of the fixed resistance (R), then the same values of current will flow through the coils. The torque(s) thus produced by the magnetic fields by each coil tends to be the same & cancels out any motion in the larger field. The pointer is in the vertical position. As the temperature of the bulb augments, so does its resistance. This leads to the current through one of the coils in the circuit-branch to augment. This leads to a stronger magnetic field being produced in one coil than in the other one. As a result, the torque on one of the coils increases, and it is pulled down to the weak point of the higher magnetic field. Simultaneously, lesser current flows through the resistance of the sensor bulb and the second coil, causing that coil to form a weaker magnetic field, which is pulled up into the stronger flux region of the permanent magnet’s magnetic field. The pointer halts turning when the fields tend to reach a new equilibrium point, which is directly related to the resistance of the sensing bulb. This would be the opposite if the temperature of the thermosensitive bulb were to drop. 

Ratiometer’s temperature measurement systems are being utilized for measuring outside air, engine oil, carburetor air as well as other temperatures in many of such types of aircrafts. These happen to be particularly useful for measuring temperature conditions wherein accuracy is more significant or where there are large fluctuations in the supply voltages.

Thermocouples happen to be the circuits or connections between 2 metals that are unlike. The metals meet at 2 different junctions. If 1 of these junctions gets heated to a higher degree temperature than the other junction, an electromotive force is generated inside the circuit. Such voltage tends to be directly linked to the temperature. Thus, the temperature can be determined by measuring the magnitude of this force. A voltmeter tends to be placed on the cooler of the 2 thermocouple junctions. This would be calibrated in Celsius/Fahrenheit (as required). As the high-temp junction (or also called the hot junction) becomes hotter, the electromotive force thus generated becomes greater & the temperature reading on the meter becomes greater!

A thermocouple is utilized for measuring high temperatures. 2 most common applications of this are measuring the cylinder-head-temperatures (CHT) in the reciprocating engines, and second is the measuring of the exhaust-gas-temperatures (EGT) in the turbine engine. The wires of the thermocouples tend to be made from several metals as per the max temperature they are being exposed. Iron & constantan/copper & constantan happen to be the most commonly used ones for measuring CHT. Chromel & alumel tend to be utilized in turbine EGT thermocouples. 

The amount of voltage generated while heating different metals tends to be measured in the units of millivolts. So, the wires of thermocouples are formed in such a way that they give a certain amount of resistance (that is usually very low) in the thermocouple circuit. Their materials, lengths or cross-section sizes could not be changed without compensating for the resulting change in the total resistance. Any wire connecting back to the voltmeter should be designed from the similar metal as that of the thermocouple’s part wherein it has been connected. For instance, a copper wire tends to be connected to the copper part of the hot junction, & a constantan wire has been connected to the constantan segment. 

The thermocouple’s hot junction has different shapes as per the application(s). The 2 most common ones happen to be the pack one and the bayonet one. In a gasket, 2 dissimilar metal rings tend to be pressed together for forming a gasket, which could be installed either under the spark plug or the cylinder that is retaining the nut. In the bayonet one, the metals are connected within a perforated protective casing. The bayonet type of the thermocouple fits into a hole or well inside the cylinder head. In turbine engines, these are installed in the turbine inlet/outlet, & then extend through the casing into the gas-stream. Note that the cylinder that runs hottest under most operating conditions is selected to mount the thermocouple to read the CHT. This cylinder’s location happens to vary for different engines. 

The thermocouple circuit’s cold junction happens to be inside of the instrument housing. As the electromotive force generated inside the circuit tends to vary according to the temperature difference between the hot & cold junctions, it is much needed to compensate for temperature changes in the cockpit of the detector mechanism that affect the cold junction. This is achieved by a bimetallic spring that has been connected to the detector mechanism. It basically works the same way as the bimetallic thermometer. With the wires disconnected from the detector, the cockpit temperature around the instrument panel could be read from the indicator dial. CHT’s number LED indicators also tend to be quite common in the modern type of the aircraft.

EGT happens to be a critical variable in the operations of turbine engines. Such EGT indicator systems tend to show the visual temperatures inside the cockpits of turbine’s exhaust gasses once they tend to leave that particular turbine unit. In some types of these turbine engines, the exhaust gas temperatures are measured at the inlet of the turbine unit. Such values are called the Turbine-Inlet-Temperature (i.e., TIT) detection systems. 

Certain types of thermocouples happen to be utilized for measuring this EGT/TIT. Such thermocouples tend to be placed at intervals circling round the circumference of that engine’s turbine case or the exhaust pipe. The small thermocouple voltages are usually increased & are utilized to drive the servo motor that moves the indicator pointer. Moving the digital drum pointer out of the cursor movement is quite a common phenomenon. The EGT indicator happens to be in a hermetically sealed device. The instrument scale tends to range from 0 degrees Celsius to 1200 degree Celsius, with a vernier scale in the upper right corner of the dial and a power failure warning flag in the lower part of the dial. 

The TIT display system visually displays the temperature of the gasses entering the turbine on the instrument panel. Multiple thermocouples could possibly be utilized with an intermediate TIT voltage. Inside the sensor are 2 thermocouples that contain 2 junctions, which happen to be electrically independent. One of these 2 thermocouples happens to be in parallel to send signals to the cockpit detector. Another set of parallel thermocouples provides signals for temperature to the engine monitoring system as well as the control system. Every such circuit happens to be electrically independent, thus ensuring the reliability of the two systems. 

The circuits for the other 3 engines happen to be quite identical to that system. The detector includes a bridge circuit, a switch, a 2-phased motor for the purpose of driving the indicator, and a feedback potentiometer. Also included is a voltage reference circuit, amplifier, shutdown indicator, power supply, & overheat warning light. The output of the amplifier activates the adjustable field of the 2-phase motor, which positions the detector master pointer & the digital detector. The motor even utilizes a feedback potentiometer for providing a buzzer signal in order to stop the drive motor at the time when the correct pointer position (relative to that of the temperature signal) is reached. The voltage-reference-circuit gives a precisely regulated reference voltage inside the bridge circuit for avoiding errors generated from fluctuations in the input voltage of the indicator’s supply of power. 

The warning light telling about over temperature tends to illuminate when TIT happens to reach the predetermined limit. An test switch (external) is ideally installed for the engines overheating warning lights to be tested simultaneously. While making use of such a test-switch, an over-temperature signal tends to get simulated inside every bridge circuit for detector temperature control. 

Digital cockpit instruments do not require the use of resistance-type indicators or the regulated servo-driven thermocouples for communicating temperature information to the pilot. The sensor’s resistance & the voltage values tend to be entered inside a suitable computer wherein they are adjusted, processed, monitored & printed on the cockpit panels. They are even sent to other computers that need temperature data to control & monitor various integrated systems.

Air temperature happens to be quite a significant parameter on which various types of performance monitoring as well as different control variables tend to depend. During the flight, the air temperature (static) is constantly changing, & accurate measurements are quite hard to get. Below Mach 0.2, a simple resistance-type/bimetallic temperature gauge could possibly give relatively correct readings for air temperature measurements. At higher speeds however, friction, air compressibility & boundary layer behaviors tend to create difficulty with correct temperature measurements. Total-air-temperature (i.e. TAT) happens to be the static air temperature added to any temperature increase due to the rapid movements of the aircraft in the air. The rise in the temperatures is called ram rise. TAT sensors are specifically designed for capturing such values accurately & sending signals for pilot detection and usage in different engine systems as well as aircraft systems. 

Simpler TAT systems tend to consist of the sensors as well as the detectors with in-built resistance-balancing circuits. The airflow through the sensor has been designed in such a way that air (at the exact temperature) tends to hit the platinum alloy resistive element. Sensors are designed in such a way that they help in detecting any changes in the temperatures versus the variations in the element resistance. When the pointer is placed in the bridge circuit, it moves in response to the imbalance caused by the variable resistance. 

More advanced systems tend to utilize the technology of signal correction as well as amplified signals that are sent to the servo motor for adjusting the cockpit indicators. Such systems consist of precisely regulated power supply as well as fault monitoring. These usually utilize digital drum-type readouts; however, they can also be sent to the LCD controllers for illuminating the LCD screens. Various LCD displays tend to be multi-functional, and they are also able to display static air temperatures & actual air speed. In a totally digital system, the correction signals tend to feed to the ADC. They can be properly processed there for cockpit displays or systems that need temperature data. 

The designs of the TAT sensors/probes are indicated by the possibility of ice formation in icy cool conditions. Sensors that are left unheated might stop working properly. Adding a heating element comprises accurate data collection. The heating of the sensors should not affect the sensor element’s resistance. 

During the design phase, special attention tends to be paid to the air flow as well as material conductivity. Some of the TAT sensors direct the airflow through the devices for influencing the ambient airflow so that it directly flows into the platinum sensors without additional energy from the sensor heaters.

Describing the Equipments for Calibration Systems

Standard PRT

Secondary SPRTs

Master Thermocouples

Dry Block Calibrator

Coefficient of Uncertainty

The equipment that is needed for performing temperature sensors’ thermal calibration largely depends upon the desirable accuracy as well as easiness of usage. The larger is the precision needed, the more demanding is the procedure as well as the costs. The equipments for Calibration Systems is usually divided into 1 of the 3 groups.

  1. The general purpose system used to test temperature sensors in industrial plants generally provides an accuracy of 1.0 degree Celsius to 0.1 degree Celsius making use of the comparison techniques. 
  2. A secondary standard system used for high-quality comparisons as well as fixed-point measurement typically provides an accuracy of 0.1 degree Celsius and 0.01 degree Celsius. 
  3. The primary standardization system makes use of the highly advanced & precise equipment for achieving accuracy better than 0.001 degree Celsius. 

Typical equipments utilized for comparison calibration include the following: 

  • A standard PRT or the secondary PRT
  • Multiple temperature baths
  • System for data acquisition
  • Temperature Sensors

For low temperature calibration, Platinum resistance detectors are utilized as SPRT & RTD forms, which are quite stable as well as highly accurate. A noble-metal thermocouple, such as an R, S type, is utilized for high temperature calibration. Such sensors should have accuracy & repeatability. 

Standard PRT

SPRT or Standard-Platinum-Resistance-Thermometer happens to be a highly accurate standard that is currently available, but it is also quite an expensive one, & other such standards are the better acceptable alternatives as per the temperature ranges covered, desired accuracies, capability , or calibration lab preferences. 

Secondary SPRTs

These are much more usable & deal with less processing interferences. It is cheaper than SPRT. 

Master Thermocouples

These are utilized as reference sensors in the comparison calibration processes. These are placed together with the calibrated sensor in quite a stable temperature zone, and their values ​​are compared & errors are calculated. 

  • Temperature Reading Methods

These devices measure the power of sensors; they should be having higher resolution as well as fine accuracy. 

  • Secondary Temperature Sources

Dry Block Calibrator

This provides a highly convenient portable device for monitoring industrial sensors & typically achieves relatively fast heating and cooling. 

Stirred Liquid Bath

Such a bath provides an excellent thermal environment for probe immersion because there’s no air gap between probe & medium. 

Ice Baths

Such a bath consists of a mixture of melting shaved ice & water. 

Negative Baths

Negative Bath & Ice Bath are primarily utilized for RTD calibration, providing negative temperature for the application of lower temperature calibration. 

Fluidized Calibration Bath

Such a bath is a unique way to obtain precisely controlled temperatures

Coefficient of Uncertainty 

In the past, test device error or inaccuracy was usually a concern when the test device was used as a reference. The concept of uncertainty is now often used in the calibration of precision instruments, where high precision is required in the measurement. This concept is viewed based on several significant parameters. Today, calibration labs must calculate & add total/expanded uncertainty to all measurements while calibrating test instruments. This should be noted that “error” isn’t “uncertainty”.

Let Us Discuss the Types of Thermal Calibration

Fixed Point Method of Thermal Calibration

Comparison Method of Thermal Calibration

Electrical Method of Thermal Calibration – Simulators & Sources

Types of Thermal Calibration

There happen to be chiefly 3 types of thermal calibration methods, which are as follows:

Fixed Point Method of Thermal Calibration

Fixed points happen to be the highly accurate devices, which are available to determine the temperature’s scale. The devices that are fixed-point in nature tend to utilize completely pure materials in sealed, inert environments; these tend to be generally delicate in nature, so, must be handled with utmost care. This method i.e. the fixed point method is basically an absolute methodology that is utilized for realizing the ITS-90 (which is the International-Temperature-Scale). The thermometer tends to be calibrated by measuring a series of temperature points that are fixed: for example melting or freezing point, triple point and vapor pressure point. This particular method consists in placing the thermometer in a cell with a fixed point, which provides an environment that is isothermal in nature. A fixed point cell is basically a flask that is almost filled completely with pure material & that is protected by a shell. The cell is placed in an apparatus, which provides fine temperature control as well as sufficient cell immersion for producing a uniform temperature in that particular measuring zone. The apparatus should have cooling that is fixed point & regulated heat. This can be a furnace; usually a vertical tube one with adequate insulation, or a liquid bath one. Multiple set points are selected. These must be as few as possible, which is consistent with creating a fine interpolation formula. Such methodology provides a very accurate calibration, and is being used only for the most high-quality thermometers. However, this is hard to implement due to the intricacy of the equipment, and the very many precautions needed to be taken for making fixed points successful. Fixed points are realized with the help of many pure substances. But, many don’t provide the necessary stability & reproducibility, and some others may also need an intricate procedure & special lab facilities.

 

Comparison Method of Thermal Calibration

In this type of method, usually the following are needed:

  1. A stable source for temperature 
  2. A calibrated master sensor
  3. A calibrated meter

 

The selectable calibration medium largely depends on the range of temperature as described below: 

  • For low temperature‘s calibration (that is usually below minus 180 degree Celsius) a copper block that is vacuum-jacketed. 
  • A controlled mixed liquid bath above minus ninety degree Celsius and up to 300 degree Celsius is the most common calibration method. Freon/alcohol could also be utilized from minus ninety degree Celsius, water at room temperature, oil up to 300 minus ninety degree Celsius. 
  • Salt-bath/liquid bath/dry-block can be used at temperatures up to 600 degree Celsius. 
  • Furnaces are more suitable for much higher temperatures. There are many models. Some have low thermal mass & fast response; while others may have high thermal mass & slow response.

 

For minimizing or reducing the temperature gradients in the bath/furnace, a metal equalizing block with thermowells is placed to receive both the standard as well as the thermometers, which are to be calibrated. This particular methodology makes it possible to cover a wide temperature range in a short time, point-by-point/continuously, & for calibrating several thermometers at the same time. However, the comparative method is less accurate than the fixed one.

Electrical Method of Thermal Calibration – Simulators & Sources

Indicators & controllers tend to be calibrated using injection signals that usually simulate thermocouples, thermistors or resistance thermometers. The simulators tend to give quite fast & comfortable methods to calibrate the instrument at several points.

Discussing about the Calibration of Sensors

Heatcon Sensors

Temperature is such a parameter that is oftentimes measured in business processes quite regularly. Various sorts of mechanical as well as electric thermometers tend to be utilized for experiencing & managing process temperature(s). Regular calibration of those thermometers is important to ensure a steady quality of the product(s) that are being manufactured, in addition to supplying regulatory compliance for a few industry verticals.

Calibration is a contrast among measurements – one in every acknowledged value or correctness made or set with 1 device & any other measurement done in the same manner as feasible with a 2nd device. The device with the acknowledged or assigned correctness is referred to as the standard. The 2nd device is the unit below check, testing instrument, or any of numerous different names for the device that is being calibrated.

Calibration of sensors is usually achieved for confirming the performance of an instrument/sensor. Calibration is the technique, which is utilized for making sure that an instrument/sensor keeps specification through the years & converting ambient conditions. Calibration of sensors is the technique that is utilized for preserving traceability of parameters almost about national/global benchmarked standards.

The technique of calibrations may be defined in as many ways as there are these methods. As per ISA’s (Automation, Instruments & Systems) dictionary, calibration may be described as – A test through which an acknowledged cost of measurement is carried out to transducers & corresponding output readings thus recorded below detailed conditions. The definition consists of the functionality to regulate the instrument at 0, and to set the favored span. The interpretation of this definition might say that the calibration is a contrast of measuring device in opposition to a standard instrument of better accuracy for detecting, correlating, regulating, rectifying & recording the accuracy of the instrument that is under comparison.

About the Inspection and Testing of the Sensors

Heatcon Sensors

Various tests are performed to ensure the quality of the sensor: 

  • Type Test: Such testing that is usually performed to demonstrate compliance with the specification is called a type test. The purpose of such a test is to show the general characteristics & design of a particular sensor sample. 
  • Routine Test: Such a test that is performed on each sensor according to the sampling plan is known as the routine test.

 

Important quality assurance tests are as follows: 

  • Inspection of Appearance & Construction: Visual inspection ensures conformance of thermocouple assembly to specification, drawing & materials. The finish of seams, joints, welds, name-plates/tagging-plates and other parts are visually inspected for any defects, dirt and roughness on the surface. If needed, welds and fittings can be subjected to a dye-penetration-test, hydrostatic pressure testing and even X-ray inspection. 
  • Dimensional Checks: Unless otherwise stated, dimensional checks are made according to the tables using a straight gauge, Vernier Caliper, and even gauges. 
  • Insulation Resistance Test: Such testing is usually performed with a super megohmmeter by applying a steep temperature gradient to the sensor assembly that has been immersed in a boiling water-bath for accelerating the condensation of residual moisture in the assembly. Such testing allows a very precise measurement of the assembly’s insulation resistance between the sheath and the terminal. 
  • Emf Calibration Tests: Such a test could be performed by two ways, one with the standard method with RTD or standard thermocouple, and second option is by the absolute method using fixed point standards in each unit or set at 3 points of the preset temperature as per the sensor type. 
  • Pressure Tests (Only for Elements That Are Sealed): The element would be tested in a hydraulic testing chamber where ice & water are in equilibrium, and they are electrically connected to a suitable indicator. The fluid pressure in the chamber should be increased to 35 kgf/cm, and then maintained for 15 mins. The element’s resistance or EMF must not deviate considerably enough from the equilibrium temperature that corresponds to the applied pressure, and when the element is later removed from that chamber, it must pass the accuracy test as well as the insulation resistance testing. 
  • Thermocouple Type Identification Test & Polarity Test: Either immersing the thermocouple in the boiling water bath above or applying hot air/flame heat to the hot-end/cold-end of the bead thermocouple to produce an EMF that allows a certain type of thermocouple to be plotted on Temperature vs. EMF-table. A DC circuit tester that is high in resolution tends to be utilized for identifying the thermocouple type & the polarity of the thermocouple’s terminal & its leg.
  • Others: Loop Resistance tests, pressure tests, X-ray tests, vibration tests, voltage withstand tests, helium leak tests, etc. could even be done if requested.

Furnace Monitoring System – Introduction 

Such systems are necessary to see the internal conditions of any hot furnace. Conventionally speaking, this used to be done through peep holes inside the furnace, however with better protections and the advent of new-found technologies, to obtain this image, the control room provided a great benefit to the operators as well as plant management. Cameras for monitoring the furnaces are utilized in cement plants, steel plants, glass plants as well as power plants; to see in the boiler furnaces, rotary kilns, melting furnaces, clinker coolers, and etcetera. Such types of systems are flexible in nature and they are quite easy in installation on the furnace wall. They have a 68°horizontal & 50°vertical field of the view; providing a better overall picture. The conventional straight view lens tube is commonly utilized in most wall-mounted boilers. The offset angle-lens could be utilized in much smaller-sized tangentially-heated boilers that are corner-fired. 

Application Information 

Cement Kilns & Coolers 

To make the finest firing decision, the kiln user must have reliable information about the kiln. The camera of the furnace offers a view into the interior of the kiln directly in that of the control room. The camera of the furnace shows the flame, monitors its length, direction and any effect that it has on the feed. Better control helps in achieving the best conditions of operating for the flame and also improves efficiency of the fuel. The temperature of the flame could also be monitored while petroleum coke or burning coal; and this is done by observing the color changes or selecting a thermal camera. The camera selected for the coolers-section offers a view in the coolers, which is crucial for monitoring the condition of the cement clinker that is quite significant for the quality of the product.

Power Utility Boilers

Cameras have been utilized for decades for viewing the interiors of the boilers operating with coal & oil heating for facilitating start-up or shut down! There is a risk of an explosion inside the boiler if the fuel does not ignite as it should, so monitoring this process will help prevent this type of any unrequired reactions. Earlier, flame detectors had been utilized for assisting light-of, but this was not quite reliable as is needed. Black & white cameras had also been utilized for helping, but were often pulled when the boiler was under full load as such cameras rarely work well across the full dynamic ranges of these boilers. Now, with the help of certain new found systems, it’s now becoming increasingly possible to constantly monitor the various condition(s) of such furnaces. 

Steel 

The camera of the furnace gives a clear-cut view of steel-slab progress in batch or even continuous steel reheating of the furnace as well as the performance of the burner. The camera here is perfectly installed near the furnace exit, above the products on opposite sides. A collective view of the cameras gives a 360-degree view of this furnace. The camera is even quite useful if it is installed below the height of the slab traveling movement. This helps to see the scale accumulated under the steel. 

Glass 

The camera of the furnace offers a clear-cut view of the inside of the glass furnace. It controls the condition of the molten glass, the health of the refractory material and the activity inside the furnace. A thermal view is used in some of the specific cases wherein the need is of obtaining a thermal view of the furnace. With the help of data recording, it is possible to analyze the life of the refectory, etcetera. Such types of cameras are also being utilized in the applications of steel kilns to view the interior of those kilns & the burner flame. A furnace camera installed at the entrance of the rolling mill helps the users to monitor the slab from the plate to the rolling mill.

Know It All about Thermowell Fitting Accessories

Metal Plugs & Socket Connections

Standard and Mini Thermocouple Connectors

 

Thermowell Fitting Accessories

Installation of the temperature sensor assemblies into a thermowell or straight inside a said process needs the utilization of a certain type of fitting that of brass/stainless-steel. This fitting tends to consist of some threaded connections, a bayonet cover (& adapters) along with a flange as well. The flange, which is somewhat adjustable, could simultaneously be utilized to assemble the sensors during the said process. The cap enables quick installation in suitable adapters, which are located inside that process; and such a technology has been used widely majorly in plastic machineries. Bushes & hexagon-plugs have been utilized while adjustments and/or removals in a much lesser significance. The selection of the fitting might be driven by the necessity for pressure integrity or also by the limitations of physical sizes. Such a compression-fitting as well as threaded brush could be supplied as well with the tapered threads for achieving a connection that is pressure-tight. 

  • Compression Fittings: The compression fittings, which are adjustable in nature, have been utilized straight over the probe for achieving the much-needed insertion length in that process, as well as for ensuring right protection of the probe(s) inside the thermowells. A compression fitting thus used to attach tubing (i.e. piping) usually has ferrules inside them. Compression fitting is thus quite popular as it does not need any kind of soldering, which makes them relatively quicker & easier to be used. 
  • Nipple Fittings: A nipple is made from the same flange family at both ends of the tube section. (Hybrid adapters are connectors with flanges of a different family on each end.) A straight nipple is made with the same-sized flange on both ends of a straight tubing-section. The reducer nipple has flanges of different sizes at both ends (that belong to the same family). 

 

3-piece unions must be utilized in dangerous places, in the junctions of pipes (conduits) & boxes or different appliances. The links consist of 3 independent pieces, which could possibly be screwed together by the rotation of the same pieces together among them. 

Terminations

Metal Plugs & Socket Connections

The connection between the thermocouple’s thermoelectric leads and the extension cables is made with uncompensated male & female connectors. The metal frame and housing of such connectors tend to ensure the continuity of protection or screening, & good temperature. 

Standard and Mini Thermocouple Connectors

The standard and mini connectors are perfect for connecting the sensors of a thermocouple along with the extension or compensation cable towards one another. The pins tend to be polarized for preventing any wrong connections and the connector body also tends to be marked with polarity. Such connectors are color coded as per the specific standards such as: IEC and ANSI etc.

Thermowell Material Selection

 

Most industrial facilities rely on some form of temperature measurement in order to monitor and control processes. One of the most critical aspects of temperature measurement is the thermowell. A thermowell is a protective sleeve that houses the temperature sensor. It acts as a barrier between the process and the sensor, allowing the sensor to be removed or replaced without disrupting the process. The thermowell is basically the component that is used to protect sensors from high temperatures. In order to prevent damage to the sensor, a thermowell is often used. This tube-like component is inserted into the process stream. The sensor is placed inside the thermowell. The thermowell protects the sensor from the high temperatures of the process stream. The thermowell also allows the sensor to be removed from the process stream without interrupting the process. Thermowells are often subjected to harsh conditions, which can lead to corrosion and wear. In order to protect the thermowell and extend its lifespan, many facilities specify a special coating for their thermowells.

Thermowell Special Coating

Thermowells are often coated with a special coating to protect the sensor from the high temperatures of the process stream. The coating also allows the sensor to be removed from the process stream without interrupting the process. The coating is applied to the thermowell before the sensor is placed inside the thermowell. The coating is applied to the outside & inside of the thermowell, to the sensor, lead wires, electrical connections, solder joints, terminals, housing, base, cover, mounting bracket, support bracket, gasket, seals, o-rings, washers, screws, and nuts & bolts.

Variety of Thermowell Special Coatings

There are a variety of special coatings that can be applied to thermowells, depending on the specific needs of the application. Some common special coatings include:

  • Teflon
  • Tungsten
  • Boron Nitride
  • Zirconia

About the Costs

Insulation

Introduction to Thermocouple Extension Leads and Compensating Cable

It’s usually desired for connecting thermocouples’ probes as parts of some very long circuits to a remotely operated unit of reference and/or some measuring instruments further away from the sensor itself. However, the expense is generally avoided of high-quality thermocouples’ cables in the longer run. It can be fine if some cheaper cable is connected, but this has to be done without worrying too much that the connection temperature is known & taken well into consideration. When thermocouples are connected to instruments, it’s necessary to use a cable with the same EMF-output as that of the thermocouple; else spurious EMFs will occur at those junctions. The finest solution hence comes with the utilization of the same material as that of the thermocouple (extension-cable). A cost-effective option is to utilize compensating cables with alloys different from those of the thermocouples, which have the same power in a limited range of temperature.

More about Thermocouple Extension Cable 

Compensating & extension grades of wires tend to be provided in the bright-annealed form. To make this happen, the extra conductor’s thermoelectric properties mustn’t vary much from that of the thermocouples. Extension & compensating cable offers a highly-convenient & quite-economical solution; with its own advantages as well as disadvantages. The extension cable nominally utilizes a similar conductor as that of the thermocouples, so that it has similar thermal characteristics and no such problems appearing with the connection. The mismatching error appearing from high temperature of the connecting-box tends to be comparatively small.

About the Costs

Such cables tend to be less expensive than thermocouples’ wires, though not quite cheap; they tend to be produced in a form suitable for long-distance transport, usually as multi-core cable or flexible wiring. These are advisable for the highest level of accuracy. Compensating cables, alternatively, tend to be less accurate but less expensive even. They use quite a variety of relatively cheaper alloy conductors’ material. Therefore, combining these would harness the same power as a particular thermocouple, but the range of operating temperature must be limited to keep the mismatch error acceptably diminutive.

Insulation

Insulation is known as the layer of polymer, plastic, or high-temp compound applied directly over the conductor. Generally, various insulations are offered along with a vast temperature range from -260 degree Celsius to 1200 degree Celsius. Most insulating materials are also being utilized for sheathing. Insulating material is selected as per their mechanical, electrical, and high-temp properties. Sheath means the outer layer of polymer, plastic, or high-temp compound applied to the cables. The outermost sheath (or better known as the jacket) is intended for mechanical protection of the insulated cores and other cable’s components.

  • Flat Tip: One end of this is having a flattened surface. This one is utilized for low-pressure applications or in places where the flow characteristics that are around the body aren’t that significant. 
  • Domed Tip: This type of protective cover has a hemispherical tip at the thermowell at one of the ends. This one is utilized in various high-pressure applications or in places where the flow characteristics, which are around it, are quite significant. 
  • Spherical Tip: For this, a special drill with 118ºC tip angle is utilized for thermowell’s production. The end is spherical i.e. in the shape of a ball, for achieving wall thickness as uniform as possible. 

Basic Thermowell Structure – Shank Construction

  • Q-Dimension: This happens to be the shank’s thickest segment on the hotter side of flange or process connection. This depends on the size of the bore & that of the process connection. 
  • Bore size: This is Thermowell’s inner diameter. This can also be referred to as the diameter of the cylindrical cavity inside the thermowell or protective tube. The standardized drilling dimensions are 6.5mm and 8.5mm. 
  • Immersion U-Length: Thermowell’s length or that of the protecting tube, which is under the flange, the mounting threads, the bushing, etcetera; extending into the area of the process. This length, ‘U,’ is actually measured from the process connection bottom to that of the Thermowell’s tip. 
  • Lagging Extension T-Length: Additionally to the standardized head lengths, the trailing extension length is required to allow access to the end of the trailing extension and allow the probe to reach through insulation/walls. 
  • Inside Mounting Thread: Thermowell’s inside thread shields to secure the junction temperature device & nipple extension for the assembly of a Thermowell. 

Flange Face Types

  • Raised-Face or RF: This is the most commonly used flange type, and this one can be easily identified. This is called an RF or the raised surface as the sealing surfaces are raised above the surface of the bolt circle. 
  • Ring-Type Joint or RTJ: Its flanges have grooves, which are cut into the surface that seal with steel rings. 
  • Flat Face or FF: This one has a sealing surface that is in the similar plane as the surface of the bolt circle. 

Thermowell Welding 

Welding is actually the process in which 2 metals are joined by heating them to a suitable temperature. This can be made with or without pressure, and with or without any filling. The 2 main types are as under:

  • Full Penetration – This particular type of weld provides a fully-welded interface between 2 parts & is usually the sturdiest joint. 
  • Partial Penetration – This particular type of weld consists of an interface that is partially welded with a filler metal placed on the surface of the 2 metals.

WPS & PQR 

WPS stands for Welding-Procedure-Specification. It is actually a document, which tends to describe the process of welding and how it should be done in production. These are advisable for all sorts of welding operations as well as the many application codes & standards tend to make them kind of mandatory.  WPQR or PQR is shortened to Procedure-Qualification-Record. This is something that supports the WPS. This is actually a test-weld that has been made & tested (quite rigorously) for ensuring a good weld with the procedure.

Types of Protection Tubes

 

Protection Tubes

Thermowell, Fittings, and Terminations are all important components of a protection tube assembly. A protection tube, also called a thermowell, is a hollow sleeve that is used to protect temperature sensing elements, like thermocouples and RTDs, from the process environment. Thermowell is available in a variety of materials, like stainless steel that can withstand high temperatures and corrosive environments. Fittings are used to connect the protection tube to the process. Common fittings include weld-in fittings, threaded fittings, and sweat fittings. Terminations are used to seal the end of the protection tube and protect the sensor from the process environment. When selecting a protection tube assembly, it is important to consider the type of process environment, the temperature range, the pressure range, and the corrosion resistance required.

Features of a Protection Tube

Thermowell fittings and terminations are an essential part of any process system. They provide a means of protecting expensive instrumentation from the hostile environment of the process. A well-designed protection tube will have a number of features that make it an ideal choice for use in a process application. These features include:

  • A smooth interior surface that is free of sharp edges or burrs. This is important to prevent damage to the instrumentation that is being protected.
  • A thick wall that is resistant to corrosion and can withstand the pressures and temperatures of the process.
  • A robust connection to the process piping that will not leak or fail under pressure.
  • A flared end that allows for easy installation of the instrumentation.

Metallic/Non-Metallic Sheath or Protection 

A metal tube, mostly stainless steel, tends to have some mechanical advantages plus an increased thermal conductivity; these are usually immune to any thermal shock(s). The metal protective sheath can possibly be utilized at temperatures up to 1150 degree Celsius. Ceramic is better when more purity is needed for the sensors or products to not contaminate at high temperatures.

Ceramic Sheaths with Thermocouple Elements 

The basic use range of the ceramic sheath is at 1000 – 1800 degree Celsius. These could be in direct contact with the medium one or could also be utilized as gas-tight inner sheaths for separating the thermocouples from actual metal protective tubes. These must be installed in a hanging position above the temperature of 1200 degree Celsius for avoiding any distortion or breakage owing to bending stress. Even any hairline crack could possibly cause contamination of the thermocouples, leading to drifts or damages. Thickness of the wall of the material is also significant; where a thin-walled tube is better than a thicker wall. Cracks often occur when they are subjected to too rapid temperature alterations when quickly removed from hot furnaces.

Types of Protection Tubes

  1. Metallic 
  2. Non-Metallic

Standard diameter of the probe ranges from 0.125. to 0.250. Small sized probes tend to react faster when they are inserted directly, however large sized probes fit much tightly into the standard protective covers. The length-range of a probe tends to vary between some inches to even 10 feet or even more than that. 

Probe Assemblies

A wide range of mounting parts as well as accessories tends to assist in the installation of sensors. The choice is largely based upon the nature of the detected carrier and the cost needs. Direct probe immersion needs a threaded connection that can be fitted well or welded to the probe. 

Flexible Resistance Thermometers

The encased probe is not very suitable for detecting flat surfaces. Unlike the junctions in thermocouples that could be soldered straight to metal surfaces, RTDs provide some mass; & heat loss to the surrounding air, which can tend to affect the reading. Small-sized flattened elements like thin films could also be mounted to the surfaces, but sensitive elements as well as wire connections tend to make the process installation much more difficult. 

Resistance Thermometer for Special Purposes

A resistance thermometer tends to adapt easily to most models of process control & thermal equipment. The users can specify axial lead enclosures for the mounting of the circuit boards, flat packages in order to clamp to the surface(s), mini enclosures for embedment in metal blocks, and any fittings & sheaths that can all be produced by a machine shop. Additionally, windings of the wires could possibly be configured for detecting larger regions. 

Applications of Resistance Thermometers

In general, resistance thermometer offers the maximum number of benefits over other types of thermometers in the following situations: 

  • High standardization is desirable 
  • Sensing of area, instead of point, betters control 
  • Accuracy should be extending over a vast range of temperature
  • Accuracy & stability being the most important application goals  

Advantages of Platinum Resistance Thermometers

  • Lesser drift 
  • Higher accuracy 
  • Wide range of applications 
  • Suitability for specific and precise applications  

Limitations of Platinum Resistance Thermometers

  • A resistance thermometer in industrial application is rarely used above 600 degree Celsius. At a temperature above 660 degree Celsius, it tends to become highly difficult to avoid contamination of the platinum with the metal shell of the thermometer. Therefore, standard lab thermometers replace the metal sheath with a glass construction. At a very low temp, say somewhere around -270 degree Celsius (i.e. 3K) or even lower than this, the reason being quite a lesser no. of photons, the resistance is principally measured by the impurities as well as boundary diffusion; and therefore, essentially temperature independent. Resultantly, RTD sensitivity is largely zero, so it is not quite useful. 
  • Compared to a thermistor, platinum resistance thermometer is less sensitive to minute temperature alterations & has a much slower reaction time. But a thermistor has a much smaller range of temperature as well as stability.

Potential Sources of Error in RTD

Heatcon Sensors

Sources of Error in RTD

RTD’s i.e. the Resistance-thermometer-systems are prone to 3 major sorts of errors:  one is the tolerances built into the thermometers inherently, second is with the gradients between the thermometer & the measuring medium, and third type of errors in the path between the sensor & the display/control device. Some error sources are purely electronic; while others can be due to the mechanical designing of the thermometers. 

  • Conformity or Interchangeability: Interchangeability or conformity defines the amount of resistance by which the thermometer is allowed deviation from the standard curve.
  • Sensitivity: The change in resistance per degree temperature change is actually the function of the base resistance as well as TCR (which is the Temperature-Coefficient-of-Resistance). 
  • Insulation Resistance: If the sensing element & the leads are not insulated fully from the housing, a bypass effect happens, wherein, the housing tends to become a parallel resistance that tends to lower the apparent values. 
  • Self-Heating: The resistance thermometers are the passive resistance sensors; they need a measured current for producing beneficial signals. As this particular measuring-current tends to heat up the cell wire above the actual ambient temperature, errors are bound to occur if excess heat is not being dissipated. 
  • Time Constant: The time constant is actually the indicator of the sensitivity or responsiveness of the resistance thermometers to any temperature changes. The rate of these responses is dependent over the thermometer’s mass as well as the rate at which heat is being transferred from the outermost surface towards that of the sensing element. A faster time constant decreases the chances of errors in the system subject to quick changes in the temperature. 
  • Repeatability: The amount of agreement between 2 consecutive readings of any thermometer happens to be its repeatability. Loss of this repeatability may lead to temporary or permanent changes happening in the element’s resistance characteristics & they can eventually lead to exposing the thermometer to temperatures which are at some specified range endpoints or above them. 
  • Stability: Being stable is a long deviation of the readings of the thermometer. A normal specification limits such deviations to only 0.1 degree Celsius per year in nominal mode. Usual services that stay well within the temperature range tend to result in very less drift. Drift is actually the consequence of the element’s material; platinum happens to be the most stable one; encapsulating those materials that can contaminate the element; as well as the mechanical stress which is there on the element due to the expansion of coils or some other supporting structure. 
  • Shock & Vibration: Mechanical shock as well as vibration tend to alter the reading of any such thermometer or can also lead to total failure. In reality, stability as well as durability is somewhat unique. Designed for maximum stability, the lab thermometers contain unsupported elements that are too sensitive for use in industrial applications. The elements of most such industrial RTDs are supported completely by the bobbin or some other packaging material, so that they can withstand even the most extreme environments quite well. 
  • Packaging & Heat Transfer: Sheaths & other such structures neighboring resistance elements must be maximizing the transfer of heat from any detected environment, and must be minimizing the transfer of heat from any environment that can change the reading, & thus provide the elements with the required protection.

Let’s Delve Deeper into the Concept of Mineral Insulated RTD

Metal Sheathed RTD

About Heatcon Sensors

 

Mineral Insulated RTD

Mineral-insulated (M.I.) resistance thermometers are usually equipped with platinum measuring resistors (i.e. Pt100 Ω) according to DIN IEC 751. The inner conductors (Cu) have been embedded in densely packed inert mineral powder (i.e. MgO) which measures that the resistor has been connected to the internal conductors; and it is also surrounded & embedded in a metal shell, thus forming an assembly that is hermetically-sealed. Constantan & nickel inner conductor(s) are also sometimes utilized. Cover is a useful protection in most of the circumstances. These are used in places where a quick response, lesser space and/or vibration resistance is required. These could be equipped with a fixed cable or a special connector that allows quick installation or replacement. Such Mineral Insulated RTD temperature sensors usually have flexible, thin-walled mineral-insulated stainless steel cables with low-resistance copper wires that have been braided in compressed heat-resistant magnesium oxide. The temp-probe is well-connected to internal wiring and placed in a stainless steel case. Thermowell & mineral-insulated cable have been welded together. Proper heat transfer between the housing & the temp-probe enables a short response time & high measurement accuracy. Anti-vibration (vibration-resistant) design ensures long service life. Temperature measurement of hard-to-reach measuring points is possible; thanks to a flexible cable with mineral insulation. The smallest bending radius is five times the outside diameter.

Metal Sheathed RTD

  • Consists of thin-walled & flexible stainless steel mineral-insulated cable. 
  • The cable consists of low-resistance inner wires, which are made from compressed refractory magnesium oxide. 
  • Temperature sensor being well-connected to internal wires & installed in the protective tube. 
  • The protective tube & sheath cable have been hermetically connected. 
  • Proper heat transfer in the protective tube & the temperature sensor enables quick response time & high measurement accuracy. 
  • Flexible sensor tubes enable measuring of temperature in hard-to-reach places. 
  • These are being utilized in heavy measuring applications with high vibration and in all measuring positions where flexibility & exchange ease have been required. 
  • Applications can be seen in power plants, chemical plants, engines, and mechanical engineering & construction facilities along with some usual industrial applications.

Gaining Knowledge about RTD Wire Configuration

Two Wire RTD

Three Wire RTD

Four Wire RTD

Heatcon Sensors

 

RTD Wire Configuration

RTD is available in 3 different types of wire configurations. The choice of such lead wire configuration is entirely dependent on the expected accuracy as well as on the instrumentation that is being utilized for measurement purpose.

Two Wire RTD

Of the 2 wires, the RTD has the simplest circuit configuration. 1 of the wires is attached to each of the sides of the element. The measurement can be made with any device that has been equipped for measuring resistance, which includes the basic VOMs (i.e. the volt-ohmmeters). This is the least accurate method of measuring temperature because the resistance of the lead wire is in serial conjugation with the sensing element. The lead wire is at a temperature different from the sensing element, and is also having varied resistance & temperature characteristics. More the length of the wire, the bigger is its effect over the measurement.

Three Wire RTD

Three-wire RTDs happen to be the most popular configurations for use in industrial applications. Three wires can be used to minimize the effect of wire resistance. Making use of this way, the 2 wires leading to the sensor are on adjacent branches. Each leg of the bridge has a lead resistor, so the impedance cancels as long as the two lead resistors are exactly the same. This type of configuration allows up to 600 meters of cable. When utilized in the correct fashion, the three-wire configuration removes any series resistance, which allows accurate measurement of the sensor element. Two wires are connected to one side of the sensor element and one wire to the other side. The resistance of L1 & L3 must be very close as much as possible; which will cause the resistance of the wire to decrease. The color code for a three-wire RTD is 2 red and 1 white.

Four Wire RTD

Four-wire RTDs are the most accurate ways of RTD measurement. They are mostly used in labs & are rarely seen in any kind of industrial applications. The 4-wire resistance thermometer configuration augments the accuracy as well as the reliability of the measured resistance: the resistance error is zero due to the resistance of the lead wire. Four-wire RTD circuits eliminate the effects of mismatched resistors in the wires. Constant current passes through L1 & L4, L2 & L3 measure the voltage drop across the RTD elements. Four-wire RTDs are mostly color-coded as 2 red and 2 white wires.

Let’s Discuss the Different Types of RTDs

Other RTDs Types

Standards of RTD

RTD Construction

 

Types of RTDs

The Platinum-RTDs are generally offered in 2 different categories; 1st is the ‘Class A’ & the other is ‘Class B.’ 

  • Class A: This one is presumed to be high in accuracy, and also, this one has ±0.06 ohms ice-point-tolerance. 
  • Class B: This one is known to have standard accuracy, and also, this one has ±0.12 ohm ice-point-tolerance. This type B is used popularly in most of the industry verticals.

Other RTDs Types

  • PRT or the Platinum-Resistance-Temperature Sensor: These provide awesome accuracy over a vast range of temperature (ranging from -200°C to even up to 850°C). 
  • Other options for resistance value: The RTD elements are even provided with resistances of 200 Ω, 500 Ω and 1000 Ω at zero degrees Celsius. These RTD types are commonly called PT200, PT 500 & PT 1000 respectively. 
  • SPRT or the Standard-Platinum-RTD: ITS-90 (1990 International-Temperature-Scale that is utilized as a global practical scale for temperatures in the laboratories of national metrology such as NIST & NPL etc.) consists of several fixed reference points as well as various interpolation devices, which are made use of for determining the scale amongst the points.

Standards of RTD

Platinum RTDs have basically 2 standards

  1. European standard (this is also called the DIN/IEC standard) 
  2. American standard

RTD Construction

RTD elements almost permanently need insulated conductors. At a temperature below about 250 degree Celsius, the PVC, silicon rubber or the PTFE-insulator are majorly made use of. Fiberglass or ceramic is used over it. The measuring point, & largely most wires, needs a housing/sleeve protection, which is usually made from metal alloys, which are chemically inert to this process that is under monitoring. 

  • Platinum Thin Film: RTD’s thin film style is perhaps the most known model due to its rugged design & less price. For making a thin film element, a small ceramic chip is covered with a very thin (0.0001″) platinum film & then a resistive path is cut or chemically etched into the platinum film. After that, the element is covered with quite a thin glass layer for protecting it from harmful chemicals as well as gases. 
  • Internal Coil Wire Wound: This type is usually made of platinum wire. A very small platinum wire (0.02 mm) is twisted & after that slipped into a small 2-hole ceramic insulator. After that, big extension wires are welded to the platinum wire ends & cemented in. Some of the manufacturers fill the insulating holes with ceramic powder after the coils are installed. This prevents the coils from moving & shorting against one another. The one end, which is right opposite the extension wires, is also coated with ceramic cement. 
  • External Wound Element: An external wound element of RTD is formed by winding the sensor element wire around the central mandrill that is generally formed from ceramic. After that, this coil or winding is covered with glass/other material for insulating so as to protect & secure the winding. These wires are then welded to the extension cords & after that secured to the frame with ceramic epoxy/cement.

Mineral Insulated Thermocouple Is One of the Types of Thermocouple Designs

Mineral Insulated Thermocouple

Advantages of M.I. Thermocouples

M.I. Thermocouples Tip Models

Non M.I. Thermocouple

 

Types of Thermocouple Designs 

2 main types of thermocouple designs are largely used M.I. thermocouple design i.e. mineral insulated thermocouple & the non M.I. thermocouple design. 

Mineral Insulated Thermocouple

This is a thermocouple design which is a magnesium-oxide insulated one, also known as the MgO thermocouple. Such types of thermocouples are mainly utilized in multiple processes & lab applications. Available in all types of thermocouple elements, in many diameter ranges and many types of materials, they are inherently durable and flexible, and their quite high temperature rating makes them a standard selection for many temperature measurement applications. Many looked-for features make them an ideal selection for general as well as special use. An MgO sensor is constructed by setting the element(s) in the sheath of suitable material as well as size, thus insulating those elements from themselves and the sheath with loosely-filled/breakable magnesium-oxide powder/insulators, and after that pulling down /drawing the filled sheath to the final diminished size. The result of the swaging procedure produces the element(s) with largely-impacted MgO insulation, & also gives raised dielectric strength insulation among the elements themselves as well as their sheath. An M.I. thermocouple consists of thermocouple wire, which is embedded in tightly-packed refractory oxide powder insulation, all of these enclosed in a seamlessly drawn metal sheath (that is mostly of stainless steel). 

Advantages of M.I. Thermocouples

  • Small size & great flexibility; this allows temperature measurement in places with poor accessibility 
  • Nice mechanical strength 
  • Protection of the wires of the thermos-element against any corrosion or oxidation or even contamination
  • Rapid thermal reaction

M.I. Thermocouples Tip Models 

M.I. Thermocouple’s junction tip could be of 3 main types. This tip can either be isolated type or grounded type or even of the reduced type. 

  • Insulated Tip: The insulated hot-end junction is best-suited for many applications, specifically when low EMF reception is mandatory. The high insulation resistance is increased by the maximum density of ultra-pure MgO powder insulation 
  • Grounded Tip: Bonded/grounded junction provides quite a speedier temperature reaction than the other insulated types. This is not advisable for multipoint instrumentation. 
  • Reduced Tip: The reduced tip junction is best-suited for applications wherein low mass & very speedy reaction time is needed and high mechanical strength is required. Such a tip can be supplied for thermocouples from 1.0 to 6.0 mm in diameter. 

Non M.I. Thermocouple

In such a thermocouple, the wires are either insulated ones with ceramic beads/after ceramic insulation, that is covered with metal jacket (mainly of stainless steel) & some type of termination (such as an extension, connector end, or plug). In such a sort of design, the leads or wires of the thermocouple are shielded from the measurement medium when protection is provided. The material of the sheath largely depends on the medium of measurement; mostly stainless steel is utilized. Depending on the corrosive environment, selection of the sheath is altered. This design doesn’t offer flexibility, and is not available in small sizes. This one does not have very good mechanical strength. In such types of thermocouples, the construction sheath could be ceramic or even metal depending on the fit. All types of open, earthed and unearthed junctions are created in the construction of both M.I. thermocouples & non-M.I. thermocouples, alike.

Let Us Know the Thermocouple Types

Base Metal Thermocouple Types

Noble Metal Thermocouple Types

Refractory Metal Thermocouple Types

 

Thermocouple Types

Several combinations of different materials are used for producing acceptable thermocouples, out of which, each has its own specific application-spectrum. But, the value of interchangeability as well as mass production economics leads to standardization, and a number of specific types are now readily available and cover most of the temperature as well as environmental applications.

Base Metal Thermocouple Types

These consist of some of the most common, and cost-efficient metals including copper, iron & nickel. The type E, type J, type K, type N, and type T belong to this group and they happen to be the most common ones.

  • E Type– This has a positive chromel leg (which is ninety percent of nickel and ten percent of chromium) and a negative constantan leg (which is five percent of nickel and 55 percent of copper) 
  • Type J – This has an iron-positive-leg & a Konstantin-negative-leg. 
  • K Type – This has a chromel positive leg (which is ninety percent of nickel and ten percent of chromium) and an Alumel negative leg (which is 95 percent of nickel and five percent of aluminum, silicon & manganese). 
  • Type N – This has a positive leg of Nicrosil (i.e. 74.1 percent nickel – 14.4 percent chromium – 1.4 percent silicon.0.1 percent magnesium) and a negative leg of Nisil (which is 95.6 percent of nickel to 4.4 percent of silicon). 
  • T-type – This has a positive leg of copper and a negative leg of constantan.

Noble Metal Thermocouple Types

They are made from wire made from precious metals such as Platinum & Rhodium. These can be utilized for oxidizing or for inert applications, & should be utilized with a ceramic protective tube outside of the thermocouple element. Such types of sensors are generally delicate and shouldn’t be utilized for applications that reduce or contain metal vapors. 

  • R Type – This is made with a positive leg of platinum or 13 percent rhodium & pure platinum negative-leg. Type R has the temperature ranging from 0°C to 1450°C (32°F – 2642°F) 
  • S Type – This is made from a positive leg of platinum or ten percent rhodium & a pure negative-leg of platinum. Type S has the temperature ranging from is 0°C to 1450°C (32°F to 2642°F) 
  • B Type – This is made from a positive leg of platinum or 30 percent rhodium.

Refractory Metal Thermocouple Types

They are made of wire made from the exotic metals tungsten 17 and rhenium. Such metals are a bit on the expensive side, hard to make, and wires made from such metals are quite brittle. So, such types of thermocouples are designed for use in vacuum ovens at very high temperatures and should not be used above 300°C in the presence of oxygen. Several different alloy combinations have been used in the past, but there is currently only one commonly used. 

  • C Type – This has a tungsten positive leg or five percent rhenium positive leg & a tungsten 26 percent rhenium negative leg. The temperature ranges from 0°C to 2320°C (32°F  to 4208°F). 
  • G Type – They are known technically as this – WM26Re. They have a combination of alloy with a positive lead of tungsten (W) and a negative lead of tungsten + 26 percent rhenium (W-26% Re). The max operating temp. of this is 0°C to 2320°C. 
  • D-Type – This is even called W3ReM25Re technically. It has a combination of alloy with a positive lead of tungsten plus 3 percent rhenium (W-3% Re) and a negative lead of tungsten plus 25 percent rhenium (W56% Re). The max operating temperature range is 0°C to 2320°C.
