Thermocouple and thermal resistance thermometer profile: the temperature is a physical quantity representing the cold and hot degree of an object, and the measurement of the temperature is one of the keys for ensuring the realization of stable, high-yield, safe, high-quality and low-consumption chemical production. The temperature cannot be measured directly, but only indirectly by means of a thermal transformation between objects that differ from the cold and hot, and the characteristic that some physical properties of the objects change with the degree of cold and hot. By using the heat balance raw material, a certain object can be selected to be contacted with the measured object to measure the temperature of the measured object, when the temperature of the selected object and the temperature of the measured object reach the heat balance state, the temperature value of the measured object can be obtained by measuring the physical quantity of the selected object. Among them, thermal resistance thermometers and thermocouple thermometers are widely used in the chemical industry.
