The principle behind thermocouple wire is that the joining of two alloys exposed to certain temperature will create a specific voltage. A different temperature will produce a different voltage. Essentially temperature can be measured using thermocouple wire and equipment that can translate the voltage reading into a corresponding temperature. Those two alloys are the wire’s Calibration.
