This temperature sensor SD 122 with a stem and plastic head with a digital output RS 485 / MODBUS RTU is designed for contact temperature measurement of liquid and gaseous substances. In combination with a central holder, the sensor is suitable for temperature measurement in air conditioning ducts. The combination of a sensor and a thermowell is suitable for direct measurement of the medium in pipelines. The temperature sensor is 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 case, where the sensing element for temperature measurement (sensor) 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 122, SD 122K – MODBUS/RTU communication protocol, communication via the RS485 bus
The temperature range of sensor use is defi ned 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.
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.
DECLARATION, CERTIFICATES, CALIBRATION
- Manufacturer provides EU Declaration of Conformity.
- Calibration – The entire production passes through a fi nal 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 off ers 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.
