Thermocouple & Extension Wire

Thermocouple extension wire is a hardwearing type of wire used for connecting a thermocouple probe to a readout instrument. Thermocouples are sensors that measure temperature across a wide range of applications in most industrial environments.

What is thermocouple extension wire made from?

Thermocouple extension wire is made from a lower grade of wire than that used in thermocouple probes, so is more economical when used at length. It's typically made with colour-coded (usually PVC) insulation applied to each wire leg. The negative lead is usually insulated in red and the positive lead is the colour of the thermocouple. For added durability and flexibility, a metal overbraid is applied to the insulated wire. For PVC wire this is a tinned copper overbraid, and for PFA it's stainless steel. This added layer protects the wire against abrasion.

Why use thermocouple extension wire?

Thermocouple extension wire is only used to extend the distance between a thermocouple probe and the instrument reading the signal. Thermocouple grade wire is used to make the sensing point of the thermocouple. Extension wire has a lower ambient temperature limit and can't be used in a thermocouple's sensing point.
