Installation requirements for thermocouples?
Thermocouple is a commonly used temperature measuring element in temperature measuring instruments. It directly measures the temperature, converts the temperature signal into a thermoelectromotive force signal, and converts it into the temperature of the measured medium through an electrical instrument (secondary instrument).
Installation method of thermocouple:
The main fixing methods are threaded connection, flange connection and welding, and their applicable occasions and requirements are different, mainly according to parameters such as pressure and temperature.
What should we pay attention to when installing and using?
1. When using the thermocouple compensation wire, you must pay attention to the matching of the model. The temperature of the compensation wire and the thermocouple connection end cannot exceed 100°C.
2. When using a thermocouple with a large time constant for temperature measurement or temperature control, although the temperature displayed by the instrument fluctuates very little, the actual furnace temperature may fluctuate greatly. A thermocouple with a small time constant should be selected.
3. After correct wiring according to the meter wiring diagram and power on, the meter first displays the thermocouple index number of the meter, then displays the meter range range, and then the lower row of the meter displays the set temperature, and the upper row of the meter displays the measured temperature.
The above interpretation of the precautions for the installation of thermocouples, we hope to help everyone!
