What is a Pt100?

Resistance Temperature Detector (Pt100)

  What is a Pt100 ?

    A platinum resistance temperature detector (RTD) Pt100 is a device with a typical resistance of 100 Ω at 0°C (it is called Pt100). It changes resistance value as its temperature changes following a positive slope (resistance increases when temperature is increasing).

    They have been used for many years to measure temperature in laboratory and industrial processes, and have developed a reputation for accuracy,repeatability, and stability. A RTD can typically measure temperatures up to 850 °C. The relationship between resistance and temperature is relatively linear as shown below for a sample 100 Ω.


    This relationship appears relatively linear, but curve fitting is often the most accurate way to make an accurate RTD measurement.

    Our laboratory is able to make such fittings based on calibration of your probes.
