Resistance thermometers

Resistance thermometers with Pt100/Pt1000 resistor

Resistance thermometers are equipped with platinum sensor elements which change their electrical resistance as a function of temperature. In our range of products you will find versions with connected cable as well as versions with connection head. A temperature transmitter can be installed directly in the connection head. Resistance thermometers are suitable for applications between -200 ... +600 °C (dependent on instrument model, sensor element, accuracy class etc.). Accuracy classes AA, A and B (per IEC 60751) apply to all resistance thermometers.

What effect does poor insulation resistance have?

In accordance with DIN EN 60751 section 6.3.1 the insulation resistance between each measuring circuit and the sheath, at a minimum test voltage of 100 V DC, must not be less than 100 MOhm. Should the insulation resistance be too low, a measuring err ... More ...
