These washer sensors which are available in thermocouple types K, T, J, E and N are suitable for surface temperature monitoring of platens, pipes and vessels etc. up to a maximum operating temperature of 400°C. The crimp washers are made from plated brass and are available in the following sizes; 0BA/M6, 2BA/M5, 3BA/M4, 4BA/M3.5, 6BA/M3, M8 and M12. The extension leads are made from stainless steel braided fibreglass cable and are then grounded to the washer.

Frequently Asked Questions

  • What is a thermocouple and how does it work?
    A thermocouple is a type of temperature sensor that generates a voltage when two different metals are joined at one end and exposed to a temperature difference between the "hot" junction (where the temperature is measured) and the "cold" junction (the reference point). This voltage is then measured to determine the temperature at the hot junction.
  • How do I choose the right thermocouple for my application?
    The ideal thermocouple depends on factors such as temperature range, accuracy, termination type, mounting requirements and environmental conditions. We offer a variety of thermocouples with different sheath materials, constructions, terminations, and temperature ratings to meet your needs. If you need specific advice, our engineers are happy to assist!
  • What is the maximum temperature rating of your thermocouples?
    Our thermocouples are designed to handle a wide range of temperatures with some mineral insulated thermocouples able to withstand temperatures up to 1400ºC and ceramic sheathed thermocouples going even higher to 1600ºC. Each product listing includes the maximum temperature rating, so you can choose the best thermocouple for your application.
