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 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.

FAQ

Why should Pt100 measuring circuits with reduced tolerance class A or AA per DIN EN 60751 be used in at least a 3- or 4-wire connection?

The 2-wire connection is not permissible for classes A and AA per DIN EN 60751 since here the internal lead resistance of the wires is added to the measured value. This will usually exceed the specified tolerance for the temperature sensor. A measu ...
