Surface Resistance Thermometers - Pt100 Sensors

What are Surface RTD Pt100s?

Surface RTDs measure temperature directly from the surface of equipment, panels, or pipes, providing accurate readings without penetration. They are ideal for applications where contact with the surface is needed but internal insertion isn’t possible.

TC specialises in the manufacture and supply of RTD Pt100 sensors and has been trusted by manufacturers, OEMs, and research labs across the UK and internationally for over 50 years.

Whether you need standard or custom-built temperature sensors for industrial, scientific, or OEM applications, our expert UK-based engineers are ready to assist, from initial enquiry through to delivery.
