Resistance Thermometers

The optimal solution for every application

Thermo Sensor resistance thermometers

Our resistance thermometers are successfully used for temperature measurements in industrial applications.

Temperature dependence of the electric resistance of metals, semi-condustors and ceramics is used as measuring effect. By voltage drop measurements the temperature-affected resistance can be recorded. 

Our sensors have a high accuracy. We are able to offer sensors made of 1/10 class B (0.03 °C at 0 °C). Having to withstand adverse conditions during long-duration measurements resistance thermometers made by Thermo Sensor are long-time stable and are frequently used in research and development laboratories.

Resistance thermometers can be easily used in the vicinity of high voltages and potentially explosive atmospheres (according to ATEX and IECEx (Ex nA)). The appropriate certificates are available. Our sensors are applicable for temperature range from -200 °C up to +800 °C.

Thermo Sensors resistance thermometers are available in many versions and different types, e.g. Pt100, Pt500, NTCs and PtCs as well as many installation options for example as bayonet caps, magnets, glue pads, protectiv tubes or screw-in sensors.

The accuracy of our sensors is guaranteed by comprehensive functional tests conducted in the final test department or the calibration laboratory.

Resistance thermometers for industrial applications are particularly heat-resistant and partly suitable for temperature ranges from -200 °C up to +800 °C, depending on the materials and components used.

Thanks to their enormous robustness thermocouples for industrial applications are versatile and primarily suitable for measuring temperatures in gaseous, liquid and plastic media. The respective characteristics particularly depend on the materials used. Frequently used materials are platin, different ceramics and heat-resistant steels.

There are various combination possibilities, e.g. regarding connecting head, installation length, extension length, connection to the  protective tube, suitable for every protective tube dimension and every application.


Typical applications:
  • Heat Treatment
  • Automotive Industry
  • Aluminium and Steel Processing Industry
  • Recycling
  • Construction and Mechanical Engineering
  • Energy Production
  • Heat Engineering
Advantages at a glance:
  • extremely heat-resistant
  • versatile
  • robust
  • suitable for temperature range from -200 °C up to +800 °C

Resistance thermometers for laboratory applications are preferably used due to their accuracy with a deviation of up to 0.03 °C at  1/10 DIN class B and their fast response times. The easy and comfortable handling yields in quick results.

All our sensors are tested with state-of-the-art devices. The guarantee for accuracy is made by our on-site calibration laboratory accredited by the DAkkS.

Upon request we can produce calibration standards which can be used in our customer's laboratories.
