Frequently Asked Questions

  • What is a thermocouple cable, and why is it important?
    A thermocouple cable 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 fibreglass) 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 extension and compensating types. Extension cables (X) use the same material as the thermocouple for accurate signal transmission, such as Type KX (Type K), Type JX (Type J), and Type TX (Type T). Compensating cables (C) use alternative alloys to mimic the thermocouple’s response over a limited range, such as Type KC (Type K) and Type SC/RC (Types S and R).
  • What insulation materials are available for thermocouple cables?
    We stock over 3 million metres of thermocouple cable with a variety of insulation material, including PVC, PFA, fibreglass, ceramic fibre, XLPE, and silicon rubber. PVC (105ºC) is a good general purpose cable, PFA (250ºC) has good chemical and oil resistance, Fibreglass (480ºC) is good for industrial use at higher temperatures and Silicon Rubber (200ºC) is a good choice if a very flexible cable is required.
