These resistance temperature sensors are designed for contact measurement of the temperature of gaseous, liquid or solid substances. Given the materials used and production technology, these sensors may also be used under very low temperatures. The maximum temperature range of use is -190 to 150 °C, where accuracy class B in accordance with EN 60751, as amended is ensured within the range of -100 to 150 °C. 

The method of use must be chosen with regard to the temperature, chemical and mechanical resistance of the case and lead-in cable.



  • Manufacturer provides EU Declaration of Conformity.
  • Calibration – The final metrological inspection – comparison with standards or working instruments – is carried out for all the products.
