Resistance thermometers

Resistance thermometers with Pt100/Pt1000 resistance

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 resistance thermometers 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 and materials coming into contact with the medium). Accuracy classes AA, A and B apply to all resistance thermometers. They are available with a tolerance value to IEC 60751.

FAQ

How high is the permissible vibration loading for WIKA-Pt100 probes?

The standard WIKA measuring insert allows use up to 3g (amplitude). This corresponds to a loading of 6g, peak to peak, per DIN EN 60751 (58.86 m/s^2). In EN 60751 only 20-30 m/s^2 peak-to-peak is specified (1 g = 9.81 m/s^2). The vibration-resistant design is suita ... More

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 characteristic. ... More
