These resistance-type sensors are intended for contact temperature measurement of gaseous substances outdoors or in industrial areas. The standard operating tempera-ture range is -30 to 100 °C. 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.

DECLARATION, CERTIFICATES,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, as amended) or in an Accredited laboratory.
