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

What does „negative temperature coefficient thermistor“ mean?

Negative temperature coefficient thermistors conduct electricity better at higher temperatures than at lower temperatures. They are also known as NTC resistances (Negative Temperature Coefficient). Typically, NTC is used in the plastics and food and beverage indust ... More

How large is the measuring error caused by the internal lead resistance with a Pt100 built into an MI cable with Cu internal wires in a 2-wire connection?

D=3 mm : 0.28 Ohm/m = 0.7 K/m (measuring error)
D=6 mm : 0.1 Ohm/m = 0.25 K/m (measuring error)
(D=external diameter of the MI cable)
