      Description

      Special thermocouples for power stations are specially designed for power stations and can meet the temperature measurement needs of 300,000, 600,000 kilowatt 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.
      Working principle of special thermocouple for 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
