The sensors can be used to measure the surface temperature of solids with a smooth surface. They consist of a cuboid-shaped metal measuring case, which contains a temperature sensing element and supply cable. The metal sensor case can be made of stainless steel DIN 1.4301 or alu- minium alloy (Duralumin). The case contains a mounting hole, allowing the sensor to be mounted on the to- -be-measured surface. The wiring of
the sensors can be 2-wire, 3-wire or 4-wire. The supply cable may have an outer PVC, silicone or PTFE (Teflon) insulation and is either shielded or unshielded. In the case of shielded supply cables, the shielding is not connected to the case or to the temperature sensing element. The total case length can be selected from the range of 40 to 60 mm, depending on the sensor case design and type of the supply cable.


  • Manufacturer provides EU Declaration of Conformity.
    The declaration is issued on the basis of the following certificates issued by the Physical-Technical Testing Institute Ostrava – Radvanice:
  • TR141Ex Certificate No. FTZÚ 16 ATEX 0145X


  • All temperature sensors pass through the final metrological inspection, which is carried out by comparing with standards or working gauges. Continuity of the standards and working gauges is ensured within the meaning of Section 5 of Act No. 505/1990 on metrology, as amended. The manufac-turer offers the possibility to supply sensors calibrated in the laboratory of SENSIT s.r.o. (according to the requirements of EN ISO/IEC 17025) or in an accred- ited laboratory.
