Description and application

TG 80, TG 81 and TG 82
diameter 8 mm, -50 °C to 400 °C

These resistance sensors are primarily designed for temperature measurement of solid substances, but can also be used for temperature measurement of liquids or gaseous substances. To mount the sensor to the measuring point, a bayonet nut is used that is screwed on a spring. The combination of a bayonet nut, spring and corresponding bayonet connector can provide higher contact pressure of the sensor to the measuring point or correct any changes in the distance between the nut and measuring point during measurement. The maximum temperature range of the sensors is - 50 to 350 °C (short-term 400 ° C). The range for individual design variations is narrowed down by the type of temperature sensing element and supply cable. The sensors meet the level of protection from IP 50 to IP 67 according to EN 60529, depending on the type of lead-in cable. The sensors are designed to operate in a non-aggressive environment. The method of use must be chosen with regard to temperature and chemical 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. 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.
