Description and application
These resistance sensors are intended for measuring the contact surface temperature. the available sensors, including fastening strap, are suitable for temperature measurement on the pipes.
The dimensions of the sensor allow the sensor to be placed even under the pipe insulation. The standard operating temperature range is between -50 and 130 ° C.
The sensitive element is constructed to be isolated from ambient influence. The sensors can be used for any compatible control system with the sensing element output signals or the output signals shown in the sensing element type table.

DECLARATION, CERTIFICATION, CALIBRATION
- The manufacturer provides an EU declaration of conformity.
- Calibration - The final metrological control - comparison with standards or working instruments - is carried out for all products. The continuity of working standards and measuring instruments is ensured within the meaning of Article 5 of Law No. 505/1990 on metrology. We offer the possibility to supply the calibrated sensors (according to the requirements of EN ISO / IEC 17025) or in an accredited laboratory.

**) Regulated by immersing the sensor in a liquid, no method error is taken into account - influence of the ambient temperature and the environment, uneven surface, etc. In terms of two connections, the impact of wire resistance be added. At a temperature of 20 ° C, the impact of lead resistance is 0,4 ° C / 1 m.
