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.
