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.


Why has there been, for some time, a separation between the accuracy classes for "wire-wound resistance" and "film resistance" Pt100 measuring resistors?

In the past, no distinction had been made between the two basic types of measuring resistor and their temperature limits.  Practice, however, showed that film resistors (thin-film/chipset resistors) have a (not insignificant) deviation form the cha ...
