WRN, WRM, WRE, WRF, WRC series thermocouples are usually used in conjunction with display instruments, recording instruments, electronic calculations, and other devices. Directly measure the temperature of liquid, vapor, gas media, and solid surfaces within the range of 0 ° C to 1300 ° C in various production processes.

characteristic

·Easy to assemble and replace

·Pressure spring type temperature sensing element with good anti vibration performance;

·Large temperature measurement range

·High mechanical strength and good pressure resistance

working principle

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