These resistance-type sensors are intended for contact surface temperature measurement. The sensors, which are available including the fastening strap and a closing device are suitable for temperature measurements on piping. The plastic connection head is provided with a cable outlet ending (the terminal board is placed in the connection head) or a connector. the standard operating temperature range is -50 to 130 °C. The proper 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. 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 For the version with connector:

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

*) The temperature sensor´s measurement error is dependent on the influence of ambient temperature, environmental variables and the characteristics of the measured surface (error of method).

**) It is recommended to apply heat-conducting paste or silicon grease to the measured surface, which will ensure faster response time and minimise the measurement error of the contact temperature sensor.
