Description and application


These resistance-type temperature sensors are intended for contact temperature measurement of gaseous substances. The plastic connection head is provided with a cable outlet bushing (terminal board is located in the head) or a connector. The standard temperature range in which the sensors are allowed to be utilised is -50 to +100 °C. The temperature sensors can be utilised for any control systems that are compatible with sensing element output signals or output signals quoted in the table of sensing element types. Easy mounting of the temperature sensor is ensured by the unique “S head” design invented by SENSIT s.r.o.

The temperature sensors are designed to be operated in a chemically non-aggressive environment.


  • lead-in connector CONEC 43-00092
  • connection cable with the straight-type RKT connector or with the rectangular-type RKWT 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) or in an Accredited laboratory.  

Caution: the temperature sensors with the output 4–20 mA and frequency output can be delivered with the new connection head only in the version A.
