These thermocouple temperature sensors are designed to measure temperatures up to 400 °C. When combining sensor and stainless steel centre holder or thermowell, supplied as accessories, the sensors are possible to be used for temperature measurement in various applications in the industrial environment, for example even as pressure equipment within the meaning of the Government Regulation No. 26/2003 Coll. as amended. Maximum permitted operating pressure is 6.3 MPa (applies for case maximum length of up to 300 mm). The thermocouple temperature sensors are possible to be used for any control systems compatible with selected thermocouple type. The standard measurement range is -50 to 400 °C and these limits must not be exceeded even for a brief period. Maximum temperature around the head is 100 °C.

The thermocouple temperature sensors are intended for operation in chemically non-aggressive environment.


  • metal central holder K 120
  • stainless steel thermowell JPTS 41
  • screw with collet or cutting rings – if different lengths of stem immersion of the temperature sensor are set


  • EU 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, as amended) or in an Accredited laboratory.
