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 A and B apply to all resistance thermometers. They are available with a tolerance value to IEC 60751
Thermocouples generate a voltage directly dependent on temperature. They are particularly suited for high temperatures up to 1,700 °C. Instrument designs from mineral-insulated sheathed cable are very resistant against extremely high vibration loads (depending on instrument model, sensor element and wetted materials).
For thermocouples, the accuracy classes 1 and 2 apply (standard and special). They are available with a tolerance value in accordance with IEC 60581 / ASTM E230
