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 (-328 °F … 1,112 °F) (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.


When talking about explosion protection, what do the zones mean?

"Zones refer to the likelihood that a flammable substance is present in an explosive (Ex) atmosphere. The lower the number, the more prolonged the hazard. European and ATEX classifications use zones, while class and division are the preferred t ...
