The thermocouple cables can also be termed as instrumentation cables, since they are used for process temperature measurement.
The construction is similar to pair instrumentation cable but the conductor material is different. Thermocouples are used in processes to sense temperature and is connected to the pyrometers for indication and control.
The thermocouple and pyrometer are electrically conducted by thermocouple extension cables / thermocouple compensating cables.
The conductors used for these thermocouple cables are required to have similar thermo-electric (emf) properties as that of the thermocouple used for sensing the temperature.
