These resistance-type sensors are intended for contact temperature measurements of liquid or gaseous substances. The plastic connection head is provided with a cable outlet ending (the terminal board is placed in the connection head) or a connector. The structure of the sensor’s stem enables the sensor to be used for direct measuring of the temperature in ducts and also ensures quick response of the sensor to changes in temperature. The standard operating temperature range is -30 to 130 °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. Easy mounting of the temperature sensor is ensured by the unique “S head” design invented by SENSIT s.r.o.

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

ACCESSORIES

lead-in connector CONEC 43-00092
connection cable with the straight-type RKT connector or with the rectangular-type RKWT connector

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.
