WR and WZ series power station thermocouples

application

Specializing in power station design, it can meet the temperature measurement needs of 300000, 600000 kW and other generator sets and auxiliary equipment. Directly measure the temperature of liquid, vapor, gas media, and solid surfaces within the range of -100 ℃ to 800 ℃ in various production processes.

Working principle

The two electrical levels of a thermocouple are composed of different conductor materials. When there is a temperature difference between the measuring end and the participating end, a thermoelectric potential is generated, and the working instrument displays the temperature value corresponding to the thermoelectric potential.
