Thermocouple Compensating Cables

In process plants and other industries it is impracticable and many a times impossible to have a cold junction at the end of thermocouple. It is therefore desirable to extend the couple to a reference point some considerable distance away. This can be achieved by the use of thermocouple extension or compensating cable.
Thermocouple extension wires and compensating cables have identical characteristics to their basic thermocouples in the restricted temperature span as is recommended in ANSI MC 96.1
With this range of cables the element conductors can be extended to a position where a stable temperature is maintained, transferring the effective cold junction to the remote end of the extension or compensating cable.
