Description

“MICRO” Thermocouple consists of two dissimilar metallic wires, the +ve & -ve wire, which have a common junction at one end (i.e. hot junction). A difference of temperature between hot end and cold end of thermocouples legs produces thermoelectric voltage, the value of which depends upon the temperature difference between the hot and cold junction.
