Description

The thermal resistance of the power station is specially designed for the power station, which can meet the temperature measurement needs of 300,000, 600,000 kilowatts and other generator sets and auxiliary equipment. Directly measure the surface temperature of liquid, steam and gaseous media and solids in the range of -200°C~800°C in various production processes.
The working principle of thermal resistance in power station
The electrode of the thermocouple is composed of two different conductor materials. When there is a temperature difference between the measuring terminal and the reference terminal, a thermoelectric potential will be generated, and the working instrument will display the temperature value corresponding to the thermoelectric potential. Thermal resistance uses the characteristics of a substance that changes in temperature and its resistance changes with it to measure temperature. When the resistance value changes, the working instrument will display the temperature value corresponding to the resistance value.
