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 cables as well as versions with connection heads. A temperature transmitter can be installed directly in the connection head. Furthermore, in the WIKA product portfolio, in addition to threaded resistance thermometers, flanged resistance thermometers or process resistance thermometers, you will also find the right measuring insert for your application.


What are the Callendar-van Dusen coefficients and how do I calculate these?

The Callendar-van Dusen coefficients are used to describe a polynomial function of the actual characteristic of a platinum measuring resistor. This can be stored in a transmitter and thus increases the accuracy of the entire measuring chain.
