These resistance-type sensors are intended for contact surface temperature measurement. the sensors, which are available including the fastening strap are suitable for temperature measurements on piping. The sensor dimmensions make it possible to place the sensor even under the pipe insulation. The standard operating temperature range is -50 to 130 °C. The sensing element is constructed to be isolated from the ambient influence. The 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.

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

Accessories

thermal conductive paste up to 200 °c, 5g

DECLARATION, CERTIFICATION, CALIBRATION

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.
