Thermocouple

A thermocouple is a temperature measurement device. It includes diverse metal wires which are joined collectively to form a joint. At the same time as the junction is hot or cold, a small voltage is generated inside the measuring thermocouple electrical circuit, which corresponds to the temperature.
