Product details about "SD room temperature sensor - Modbus RS485"

Room sensor

The indoor temperature sensors with RS 485 / MODBUS digital output - GSD 102R consist of a plastic head with grooves in which is placed a printed circuit board with individual sensor or 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 the protection class IP30 in accordance with the modified EN 60529 standard. 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 should be selected according to the temperature and chemical resistance of the sensor head.
