Platinum RTDs & Linear PTC Sensors

Why use a Platinum RTD Sensor?

Platinum Resistance Temperature Detectors (or PRTDs) are highly stable temperature sensors widely used throughout many industries, controlling temperatures up to 500°C or even higher.

Our Pt elements are manufactured by Heraeus using a thin layer of Platinum deposited onto a ceramic substrate which is then laser-trimmed to meet the exacting requirements of DIN EN 60751 (IEC 751). They have a linear PTC characteristic which is very well defined and readily interchangeable with other Pt elements of the same tolerance class; Class A, Class B, 1/3 DIN etc.
They have been used for many decades to measure temperature in laboratory and industrial processes and have a deserved reputation for high accuracy, excellent repeatability and high stability.

Typical applications include;

  • Automotive electronics
  • Industrial electronics
  • Medical electronics

We also supply IP68 rated Platinum sensors and SKTY PTC linear sensors which have a steeper slope offering improved accuracy up to 150°C.

Call us today on 01606 871680 to discuss your application’s thermal sensor requirements.  Using our extensive technical knowledge and innovative supplier base, we will work with you to provide the optimum solution for your product.
