Working principle of armored thermocouple WRNK

Armored thermocouple WRNKWorking Principle:

The electrodes of armored thermocouples are composed of two metal materials with different conductors. When there is a temperature difference between the measuring end and the reference end, a thermoelectric potential is generated, which is called the output millivolt signal (mV). The working instrument will use this principle to convert and process this thermoelectric potential, so that it can display the corresponding temperature value.
