The structural form of the thermocouple in order to ensure the reliable and stable operation of the thermocouple, its structure requirements are as follows:
1, the composition of the thermocouple two thermoelectric electrode welding must be firm;
2, two thermoelectric poles should be well insulated from each other to prevent short circuits;
3, compensation wire and thermocouple free end of the connection to be convenient and reliable;
4, protection casing should be able to ensure that the thermoelectric pole and harmful media fully isolated.
