A thermocouple is formed when two wires (so-called thermo wires), made of different metals or alloys, are welded together (hot junction). The free ends of the wires form a reference junction (cold junction).
If there is a temperature difference between the welded and the reference junctions, thermal electromotive force (voltage) will appear in the thermocouple.

Thermocouple Extension CablesThermocouple sensors must be wired with right kind of materials between hot and cold junctions, in order to avoid measurement deviation caused by thermo voltages in connections of different materials. Cable types used are extension wires (X) or compensating cables (C).
SKS Automaatio's stock items are silicon insulated compensating cables according to IEC 584, with maximum temperature +180 °C. The wire structure of one pair cables for J, K and S type TC sensors is 2 × 1,5 mm².
