This RS 485 / MODBUS - KSD 102 digital output temperature sensor for interiors is designed to measure the temperature of gaseous substances in spaces protected against water. In the application segment of railway vehicles, it is used to measure the temperature in the passenger compartments of train units and wagons and is part of the temperature control system.

The temperature sensor with RS 485 / MODBUS digital output - KSD 102 for interiors consists of a plastic ribbed head, where a printed circuit board with the individual sensors or a converter is placed to establish a particular digital output according to the type of sensor. Appropriate design and high-quality materials ensure that the sensors are not disturbing, even in interiors with high aesthetic requirements. You can choose the color of the box white or gray.

The temperature range of use of the sensors is defined in the table of technical parameters for the different versions of the sensors. The sensors meet the protection index IP 30 according to EN 60529, as amended. Installation is recommended on an interior wall at a height of 1,5 m, in areas of movement of people, in places not exposed to direct sunlight and not influenced by the heat of walls, heating radiators or lighting.

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