Moving Surface Thermocouple (Type 8)
General Purpose Thermocouples
For temperatures up to 250°C and rotating and linear speeds up to 275 metres per minute, Type 8 sensors are suitable for use on calendar rolls, motor shafts and flat sheets of metal, plastic and textile surfaces with low abrasion resistance.
The assemblies are available with a long life, low friction spring loaded detection head incorporating thermocouple conductor types K, T, J, N, or E. They are supplied complete with a built in thermocouple socket, matching plug and mounting bar. Thermocouple extension leads should be ordered separately. Spare replacement thermocouple cartridges are also available (order code S8). If further information is required please contact the company for our detailed technical bulletin.

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.
