This contact temperature sensor with a digital output ZacWire / TSic x06 SD 146 is intended for contact surface temperature measurement. The sensors are supplied with a fastening strap and cap and are suitableb for temperature measurement on pipelines. The sensing element itself is insulated from the environment. The temperature sensors are easy to install thanks to the unique “S-head” design of the SENSIT s.r.o. company.

The sensors consist of a plastic head and a metal measuring case placed in a protective plastic, POLYAMIDE cover where the sensing element (sensor) for temperature measurement is placed. In the head, there is a terminal block with a converter located, to which a supply cable for sensor supply and digital output signal according to the sensor type is connected through a cable grommet or a connector.

SD 146, SD 146K – TSic 206, 506 and 716 digital temperature sensors, ZACWire communication protocol

The temperature range of sensor use is defined in the table of technical parameters for the individual versions of sensors. The sensors meet the ingress protection of IP 65 according to EN 60529, as amended. In order to ensure high accuracy of measurements, it is recommended to clean the contact surface with a file and to use a thermally conductive paste between the measured surface and the metal sensor case.

The sensors are designed to be operated in a chemically non-aggressive environment, the use must be chosen with regard to the temperature and chemical resistance of the sensor head.

ACCESSORIES

CONEC 43-00092 connection plug
connection cables with a straight RKT connector or a right-angled RKWT connector
thermal paste up to 200 °C, 5 g

DECLARATION, CERTIFICATES, CALIBRATION

Manufacturer provides EU Declaration of Conformity.
Calibration – The entire production passes through a final metrological inspection, which is carried out by comparing with standards or working measuring instruments. Continuity of the standards and working measuring instruments is ensured within the meaning of Section 5 of Act No. 505/1990 on Metrology. The manufacturer offers to supply the sensors calibrated in the SENSIT s.r.o. laboratory (according to requirements of the EN ISO/IEC 17025 standard, as amended) or in an accredited laboratory.

*) A temperature sensor measurement error depends on the ambient temperature and environment and the properties of the measured surface (method error) and can be within ± 1 °C.

**) 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.
