When connecting two ends using two different kinds of metals (i.e., hot contact) and keeping the other end of the connection at zero degree C (i.e., cold contact) to form a close circuit and in the process of temperature change at the hot contact, there will produce a minute thermal electromotive force (EMF). With the thermal EMF value, we can calculate the temperature, which is the thermocouple.
