Although thermocouple is widely applied in industry, but because of its temperature range make its application is limited by a certain, thermocouple temperature measurement principle is based on the conductor or the resistance of the semiconductor characteristics of the changes with temperature changes. Integration of thermocouple bimetallic thermometer works 1, integration of thermocouple bimetallic thermometer, bimetallic thermometer selection criteria, the detailed description of bimetallic thermometer: usually and digital display table, recording instrument, such as electronic computing systems. Direct measurement of the - in the process of production Within the scope of 200 ° c to 500 ° c liquid, steam and gas medium, as well as solid surface temperature. Integration of 2, thermocouple, bimetallic thermometer features: reed pressure temperature sensing element, ant-vibration performance is good. Without compensation conductor, saves the cost; High precision temperature measurement; High mechanical strength, good compression performance; Imported film resistance element, reliable, stable performance. 3, how it works: thermocouple is the use of the material when the temperature changes, its resistance also along with the change of characteristics to measure temperature. When resistance changes, the work shows the temperature resistance of the meter. Although thermocouple is widely applied in industry, but because of its temperature range makes his application by certain restrictions, thermocouple temperature measurement principle is based on the conductor or the resistance of the semiconductor characteristics of the changes with temperature changes.
