Base Metal Thermocouples


Base metal thermocouples are widely used to measure temperature in high and low pressure applications. They are reliable, durable, and highly accurate. However, they need to be protected from thermal shock and other environmental conditions, so they are often installed with thermowells or protection tubes.

Thermowells provide a barrier between the environment and the thermocouple, so that sudden changes in temperature do not affect the accuracy of the measurement. Thermowells also provide protection from mechanical damage and pressure surges. Protection tubes are used to insulate the thermocouple from the environment, and provide a physical barrier between the thermocouple and the environment. By using both thermowells and protection tubes, base metal thermocouples can be used in a wide range of temperature measurements. 


With Heatcon, you can rest assured that you are receiving the very best when it comes to base metal thermocouples with thermowells/protection tubes.

Our Quality Is Centric!

Base metal thermocouples with thermowells or protection tubes are a reliable method of measuring temperature in the industrial environment. These types of thermocouples are made of different metals including steel, iron, and nickel alloys, and provide accurate temperature readings. They are usually mounted in a thermowell or protection tube, which provide a level of protection against mechanical damage and corrosion. This makes them durable and long-lasting and suitable for use in harsh environments. Temperature readings can be taken quickly and easily, and they provide a safer way to measure temperatures in confined spaces. 


Base metal thermocouples with thermowells or protection tubes are ideal for applications where temperature precision is critical, and they are usually used in the oil and gas, petrochemical, and power industries. Heatcon Sensors offers an extensive range of Base Metal Thermocouples with Thermowells/Protection Tubes for industrial applications. These thermocouples are designed to provide reliable monitoring and control of temperatures in harsh environments. Our thermocouples are perfect for installation in locations that need to be protected from extreme temperatures and vibration. The thermocouples are highly accurate, made of high-quality materials, and are easy to install. The thermowells/protection tubes serve to protect the thermocouple from physical damage and also help to ensure that the temperature readings remain accurate.

No Compromise with Quality!

Metal thermocouples are an increasingly popular choice for temperature measurement applications, offering superior accuracy, durability, and cost-effectiveness compared to other types of thermocouples. To ensure reliable operation, base metal thermocouples should be used with thermowells/protection tubes. Thermowells are cylinders that protect the thermocouple from surrounding elements, while also allowing flow around the sensing element. Protection tubes, on the other hand, are designed to isolate the thermocouple from high-pressure or highly corrosive environments. Both thermowells and protection tubes provide additional insulation to the thermocouple, ensuring that it accurately reads the temperature. When using base metal thermocouples with thermowells/protection tubes, it is important to choose the correct size and material. 


A thermowell that is too small can cause turbulence in the flow and inaccurate readings, while a thermowell that is too large can affect the response time of the thermocouple. The material chosen should be compatible with the environment in which it is used, and must be able to withstand the temperature and pressure of the application. In summary, base metal thermocouples offer superior accuracy and durability compared to other thermocouples. To ensure reliable operation, it is important to use them with thermowells/protection tubes that are the correct size and material for the application.
