RTD Cable - Fibreglass Insulated with Stainless Steel Braid

RTD Resistance Thermometer Cables

  • The following leads and cables are suitable for connecting to our range of Platinum Resistance Thermometer assemblies. Some are quite small and are ideal for extending out of an assembly pot seal but can be unwieldy for longer runs. Others are more robust, offer greater mechanical strength and are more suited for extending out of an assembly connection head or for use in connecting to junction boxes.
  • Whilst some of these cables are suited for longer cable runs, our range of single and multipair instrumentation cable may be more suitable for such applications.

Frequently Asked Questions

  • What is an RTD cable, and why is it important?
    An RTD (Resistance Temperature Detector) cable is designed to connect an RTD sensor to measurement equipment. It transmits the resistance signal generated by the RTD sensor, which is then used to accurately measure temperature. The choice of cable material and construction is essential for ensuring the cable can withstand the conditions of your application, such as temperature range, flexibility, and resistance to environmental factors.
  • What are the different types of RTD cables available?
    RTD cables are available in 2, 3, 4, 6 and 8-core variants in a variety of materials, including PVC, PFA, silicone rubber, and fibreglass. Each material is suited for different temperature ranges and environmental conditions. For example, silicone rubber is flexible and ideal for low to medium-temperature applications, while PFA offers higher temperature resistance and is suitable for more demanding environments.
  • How do I choose the right RTD cable for my application?
    Choosing the right RTD cable depends on factors like temperature range, flexibility, and environmental resistance. For higher temperature applications, materials like PFA (250ºC) or fibreglass (480ºC) are ideal, whereas for general-purpose or lower-temperature use, PVC (105ºC) or silicone rubber (200ºC) cables may be more suitable. Please check the specifications of each cable to ensure it matches the needs of your application. Our engineers are also available to provide tailored advice.
