Room sensor

Indoor temperature sensors with digital output RS 485 / MODBUS - SD 102 consist of a plastic head with grooves in which is placed a printed circuit board with individual sensors or a converter in order to guarantee a specific digital output according to the type of sensor. 

The temperature range of the sensors is defined in the table of technical parameters for each variant. The sensors comply with protection class IP 30 in accordance with the modified standard EN 60529. The recommended location is at a height of 1,5 m on the interior wall, in the area of ​​movement of people, away from sunny places and places affected by the temperature of walls, radiators or light.

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