Important Tips For Installing Extension Wires Correctly!
How To Go About General Maintenance of Thermocouple!
A thermocouple is a vital piece of equipment for many industries to adequately measure and maintain temperature of objects in process, especially for processes that work at extreme temperatures. Its efficiency can make a huge difference between a successful operation and a costlier one. Here are some important tips to consider before installing thermocouple to make sure it keeps working at its peak performance.
- Location Is Key – The thermocouple should be placed in an area where it can accurately measure the temperature. If it is too close to a heat source, it will not be able to give accurate readings.
- Insertion Depth Must Be Adequate – Carefully select and ensure proper placement and the correct insertion depth to make sure the temperature it records represents the actual process temperature.
- Avoid Stem Loss – Make sure that the immersion depth of the thermocouple is at least 10 times the diameter of protection tubing to avoid stem loss.
- Make Sure It Is Level – A level thermocouple is essential for accurate readings. If it is not level, the readings will be inaccurate.
- Use The Correct Wiring – The thermocouple must be wired correctly in order to work properly. Using the wrong type of wire can cause problems.
- Inspect The Tip – The tip of the thermocouple should be clean and free of debris. Any dirt or debris on the tip can cause inaccurate readings.
- Check The Calibration – It is important to check the calibration of the thermocouple regularly. This will ensure that the readings are accurate.
- Check Proper Insulation – Always check for the thermal conductivity of the materials around the thermocouple in order to properly insulate it while installing the thermocouple.
- Keep It Protected – The thermocouple should be properly installed at a convenient location in order to keep it protected from physical damage and from extreme temperatures that are way beyond its actual calibration.
Important Tips For Installing Extension Wires Correctly!
- Make sure to use correct extension wires that are compatible with the thermocouple calibration.
- Use the correct color code to connect the negative wire to both the negative terminal at both the instrument and the head of thermocouple connection.
- Try not to run the thermocouple wires parallel to or in the same conduit and always try to keep it away from the power source at least 12”.
- Always use shielded conductors and twisted thermocouple extension wires with a drain wire in place in highly noisy conditions.
- Use appropriate insulation to meet the exact thermal conditions for best performance.
How To Go About General Maintenance of Thermocouple!
- Base metal thermocouples generally do require monthly maintenance, however, frequency of periodic checks can be increased based on individual situations.
- The rotary switches must be kept free of oxidation and cleaned regularly especially at the points of contact.
- While reinserting a thermocouple, make sure there are no changes in the depth of insertion or at least try not to decrease it which may result in errors.
- For a type K thermocouple to remain accurate, make sure to not expose it to temperatures beyond 16000 F when it is calibrated for temperature measurements up to 10000 F.
- Always ensure to discard or replace the thermocouple which has burned-out protective tubing.
