Multipair Thermocouple Cables - Single Pair

Send Enquiry Buy OnlineRequest Info Data Sheet
  • Extremely useful where there is a need to run a number of thermocouple signals back to instrumentation
  • 16/0.2mm dia (0.5mm2) conductors with an individual and collective screen. Cores, bedding and overall sheath in flame retardant Silicone Rubber
  • Ideal for applications where, for short periods of time, the temperature can fluctuate, which would cause other cables to become inflexible and brittle.
Non Armoured FR Silicone Rubber Multipair
Multipairs of stranded 16/0.2mm dia conductors FR Silicone Rubber insulated. Pairs numbered, twisted and individually screened with Mylar® aluminium tape with a drainwire. Pairs laid up, overall screened with Mylar® aluminium tape with a drainwire. FR Silicone Rubber sheathed.

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.
