The armoured thermocouple has the characteristics of large measurement temperature range, high reaction speed, small dynamic error, flexible installation, high mechanical strength, good pressure resistance and the like. Armoured thermocouples can typically measure gas, liquid and vapor and solid surface or internal temperatures in the range of 0-1300 ℃. The basic principle of the thermocouple for measuring temperature is thermoelectric effect, and two metal conductors with different components are connected end to form a closed loop, if the temperatures of the two joints are different, thermoelectromotive force can be generated in the loop to form thermoelectric current, which is the thermoelectric effect. Thermocouples are formed by welding two ends of different metal materials, one welded end being called a measuring end and the other unwelded end being called a reference end, the reference end being normally kept at a certain temperature (e.g. 0 ℃) during use, and when the measuring end is heated, a thermoelectric voltage is generated at the junction. If the temperature of the reference end is constant, the magnitude and direction of the thermoelectric voltage are only related to the characteristics of two metal materials and the temperature of the measuring end, and are not related to the fineness and the length of the potential couple. When the temperature at the measuring end is changed, the potential is changed, and a fixed functional relation exists between the temperature and the thermoelectric potential, so that the temperature can be measured by using the relation.
The thermocouple has internal stress after being drawn, and if the thermal treatment is not used for eliminating the stress, the thermocouple can not reach a certain stability during working.
