Thermocouple Extension Wire

Thermocouple Extension Wire
Thermocouple extension wire is a single pair wire that cannot be made into a thermocouple, but is used to carry the signal from a thermocouple to the recorder, controller, or instrument reading the signal.

Extension grade wire is used to carry a signal representing the higher temperature seen by the sensing location, but extension wire itself cannot be generally exposed to those higher temperatures.

Extension wire cannot be used to make a thermocouple, but thermocouple wire can be used as extension wire. Insulation is typically PVC, but other option are available.

ThermocoupleMulti-pair extension wire is simply more than a single pair in the same jacket.  It is extension onlyand is usually available in 2, 4, 6, 8, 12, 16, and 24 pairs. It is used primarily when a contractor has to run multiple runs of wire. It allows them to run one piece of wire rather than multiple individual runs.
