Thermocouple Wire - PFA Insulated Parallel Construction

Thermocouple Wire and Extension Wire - Single Pair
PFA Insulated Parallel Construction Thermocouple Wire

  • PFA is ideal for higher temperature
    applications up to 480°F (short term 570°F).
    It is also excellent for cryogenic temperatures down to –100°F
  • Withstands attack from virtually all known chemicals, oils and fluids. All our PFA cables are gas, steam and water tight which makes them most suitable for applications such as autoclaves or sterilizers
  • A wide variety of constructions from simple twisted pairs to shieldeded types in virtually all the thermocouple combinations

Frequently Asked Questions

  • What is a thermocouple cable, and why is it important?
    A thermocouple wire is used to connect a thermocouple sensor to measurement equipment. It transmits the temperature signal generated by the thermocouple, ensuring accurate readings are maintained. The choice of cable material (such as PVC, PFA, or fiberglass) affects the cable's durability, temperature range, and resistance to environmental factors, making it critical to select the right one for your application.
  • What are the different types of thermocouple cables available?
    Thermocouple cables are categorised into thermocouple and extension types. Thermocouple grade cables use the same material as the thermocouple and are used to make the sensing part of the thermocouple, designated by two letters such as Type KK (Type K), Type JJ (Type J), and Type TT (Type T) etc. Extension grade wire can only be used to extend ther thermocouple to the instrumentation, these are designated as type KX, TX, JX etc.
  • What insulation materials are available for thermocouple cables?
    We stock over 7 million feet of thermocouple cable with a variety of insulation material, including PVC, PFA, fibreglass, ceramic fiber, XLPE, and silicone rubber. PVC (220ºF) is a good general purpose cable, PFA (480ºF) has good chemical and oil resistance, Fibreglass (890ºF) is good for industrial use at higher temperatures and Silicon Rubber (390ºF) is a good choice if a very flexible cable is required.
