TR 091.5
diameter 1.5/4 mm

Description and application

TR 091.5
diameter 1.5/4 mm

These resistance temperature sensors are designed for contact measurement of the temperature of gaseous and liquid or solid substances. The maximum temperature range -50 °C to 200 °C. The 1.5 mm diameter of the case ensures fast response to changes in temperature. Various cable materials with a PVC, silicone of teflon insulation can be used as lead-in cables. The sensors are designed for universal use. The method of use must be chosen with regard to the temperature and chemical resistance of the case and lead-in cable.

The sensors are also designed for use in a chemically non-aggressive environment.



  • EC Declaration of Conformity – in accordance with Act 22/1997 Coll. on technical requirements on products as amended.
  • 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.
