WRNK2-231 armored thermocouple consists of junction box, terminal block and armored thermocouple, and is equipped with various installation and fixing parts. The thermocouple is formed by welding two ends of conductors with different compositions to form a loop. When there is a temperature difference between the two ends, a thermal current will be generated in the loop, and the display meter will be connected, and the meter will indicate the corresponding temperature value of the thermoelectromotive force generated by the thermocouple.
Armored thermocouples are generally used in conjunction with display instruments, temperature regulators, recording instruments, etc., and can directly measure the temperature of fluids, steam and other media in the range of 0-1800 °C in the production process.
