These resistance temperature sensors TR021F with a connector are designed for temperature measurements of gaseous or liquid substances. The temperature range is -50 to 150 °C and these limits must not be exceeded even for a brief period. The temperature sensors with a connector consist of a metal case, in which the temperature sensing element is placed, and Lumberg M12 connector, which is an integral part of the case. The temperature sensors with a connector meet ingress protection IP 67 according to EN 60529, as amended and they are designed for temperature measurement in pipelines.

The temperature sensors with a connector are intended to be used in operation in chemically non-aggressive environment, the use must be chosen with regard to temperature and chemical resistance of the case and the connector.



  • Manufacturer provides EU Declaration 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.
