  • Summary

Type K thermocouple


Cartridge heating element

General Description


As sensor for temperature measuring and regulation, industrial-purpose thermocouple is usually connected with display meter and other meters to directly measure temperature of liquid, vapor, gas and solid surface ranging from -40to 1600.


Operation Theory of Thermocouple


Thermocouple is based on physical phenomenon that two conductor of different materials is connected to form return circuit, when temperature on both contact is different, it results in thermoelectric potential in return circuit.
