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 has been a trusted manufacturer and supplier of RTD Pt100 sensors for more than 50 years, serving manufacturers, OEMs, and research laboratories across the United States.

Our experienced engineers are ready to support you from initial consultation through delivery, helping you select the right temperature sensor to match your specific application.
