This temperature sensor with a digital output RS 485 (MODBUS) - SD 112A for outdoor environment is designed for contact temperature measurement of gaseous substances in outdoor or industrial areas, on building walls, but also in rooms, offices or in production halls. The temperature sensors are easy to install thanks to the unique “S-head” design of the SENSIT s.r.o. company.
The temperature sensor with a digital output RS 485 (MODBUS) - SD 112A for outdoor environment 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 112A, SD 112AK – MODBUS/RTU communication protocol, communication via the RS485 bus
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. Recommended installation of the sensor:
- for measurement of outdoor air temperature – the installation is recommended on the coolestside of the building (the northern or the northwest one) in a way that the sensor is not 097.11en exposed to a direct sun light. The installation is recommended in 2/3 of the height of the building wall.
- for measurement of indoor air temperature in rooms, offices or in production halls – the installation is recommended on an inner wall at the height of 1.5 m, in areas of movement of persons, at places not exposed to sunlight and not influenced by heat from heating radiators or lighting
The sensor is 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 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.
