Thermocouple wire is part of the construction of a thermocouple temperature sensor or the sensing point (or probe part) of the thermocouple. It performs even in exceptionally high temperatures. There are multiple types and grades of thermocouple wire. Each type of thermocouple wire has a specific combination of metal alloys. This combination is what defines what type of thermocouple it is. Our stock of thermocouple wire includes a full range of insulation and conductor types.

FEP, TFE, PFA, Fiberglass, and CERAMAFLEX Thermocouple Wire function exceptionally well as a high-temperature cable in many applications. FEP Wire and PFA Insulated Thermocouple Wire are suitable for use as general use extension wire. TFE Wire is suitable for use in aircraft and petroleum processing applications. Fiberglass Wire is ideal for general applications requiring moderate abrasion, moisture resistance, and wide temperature capabilities. CERAMAFLEX Wire is an excellent probe in high-temperature applications. 

Although every high-temperature cable we stock operates well in high-temperature environments, some cables can withstand higher temperatures than others. Service temperatures (maximum temperatures) for the high-temperature cable above range from 400°F to 2200°F. CERAMAFLEX is even suitable for intermittent use in temperatures up to 2600°F. When deciding the best high-temperature cable for your requirements, be sure to examine conductor listings. For thermocouple wire, conductors have a "Type" designation label that refers to the materials in the wire. 

If you have any questions about any of these products, please contact an Allied Wire representative. We are happy to help find a high-temperature cable that meets your requirements.
