Duro-Sense Thermocouple Wire and Thermocouple Extension Wire

Insulated thermocouple wire is single pair wire that can be made into a thermocouple. Thermocouple wire is made from two dissimilar metals conductors that are joined (welded) together at the sensing end. Different metal wires are used for the various types of thermocouple types (J, K, T, E, etc). These dissimilar metals produce a millivolt electrical signal at the cold junction that is proportional to the change in temperature at the sensing end. Thermocouple wire has two grades; standard and Special Limits of Error. Special Limits of Error wire is made of the same metals as standard wire, but uses a higher grade with increased accuracy and higher expense than standard thermocouple wire.

Thermocouple extension wire is a single pair wire that cannot be made into a thermocouple, but is used to carry the signal form a thermocouple to the recorder, controller, or instrument reading the signal. Extension grade wire usually has lower ambient temperature specifications. It is used to carry signal representing the higher temperature seen by the sensing location, but extension wire cannot be generally cannot be 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.
