Explosion-proof thermocouple thermoelectric potential is produced

Explosion-proof thermocouple will produce thermoelectric potential; When measuring the temperature difference is with the reference, the produce thermoelectric power, the instrument will show thermoelectric potential corresponding temperature value. A wide application in the chemical industry control system, through the temperature sensor, can control the temperature of the object parameters into electrical signals, to directly measure and control the production process of gas, liquid and steam temperature. If use common thermocouple is not safe and easy to cause environmental gas explosion. On these occasions, therefore, must use explosion-proof insulation thermocouples as temperature sensor, a temperature measurement and control of sensor and display instrument,? To directly measure and control the gas in the process of production. Have enough internal space, thickness and mechanical strength, thermal stability of the rubber sealing ring are in line with the state explosion proof standard. More than verification cycle of thermocouples are not allowed to be used as a transfer. Such as explosion-proof thermocouple is not used after the test or the use of less than 200 h, low temperature at one end of the end for freedom, the free end are usually under a constant temperature. According to the thermoelectric emf as a function of temperature, a single or double checked thermocouples inserted hole high aluminum insulation tube, and then checked thermocouple around the end of the measuring end along the standard thermocouple is uniformly distributed, 1000 ℃ when measured values of thermoelectric emfs, before and change the insert depth of thermoelectric emf measured values of the poor.
