If two wires of different metals are connected at their ends and one of them is subjected to a change in temperature, a Fem appears in the circuit. This is the thermoelectric or Seebeck effect.
The electromotive force generated is a function of the nature of the two conductors and of the temperatures of the two junctions: these are called respectively hot junction and cold junction. One of the junctions is usually maintained at a reference temperature (eg 0 ° C), the other is the temperature measurement point.
The most used sensors are those defined in standard IEC 60 584-1 (International Electrotechnical Committee).
