In order to ensure the reliable and stable operation of the thermocouple, the structural requirements of the thermocouple are as follows:
① The welding of the two hot electrodes that make up the thermocouple must be firm.
② The two hot electrodes should be well insulated from each other to prevent short circuit.
③ The connection between the compensation wire and the free end of the thermocouple should be convenient and reliable.
④ The protective sleeve should be able to ensure that the hot electrode is fully isolated from the harmful medium.
