These resistance temperature sensors are designed to measure the temperature of gaseous or liquid substances. The maximum temperature range of use of the sensors is -50 to 250 °C. Used type of lead-in cable has silicone insulation and shielding. The production technology and diameter of the case enable quick response to changes in temperature even up to a temperature of 250 °C. The sensors are designed for use in a chemically non-aggressive environment. The method of use must be chosen with regard to the temperature and chemical resistance of the case and lead-in cable.



  • Manufacturer provides EU Declaratin of Conformity.
  • Calibration – The final metrological inspection – comparison with standards or working instruments – is carried out for all the products. Continuity of the standards and working measuring instruments is ensured within the meaning of the Section 5 of Act no.505/1990 on metrology. The manufacturer offers a possibility to supply the sensors calibrated in SENSIT s.r.o.’s laboratory (according to requirements of the EN ISO/IEC 17025 standard, as amended) or in an Accredited laboratory.
