Temperature and humidity probe - CAN

Reference GSTH104R

Sensor temperature and relative humidity - STH 104 is designed to measure temperature and relative humidity in areas protected from water.

Temperature and relative humidity sensor - The STH 104 consists of a plastic head with ribs in which a printed circuit board with individual sensors and a converter are located to ensure communication via CAN protocol. The temperature and relative humidity are measured by a common internal sensor. microprocessor and converted into CAN output signal. The sensors comply with protection class IP 30 according to EN 60529.

The sensors are designed to be mounted on a wall or other vertical surface. For fixing, it is necessary to prepare the required holes for mounting screws using a template (supplied with the sensor).
Before connecting the power cable, it is necessary to separate the perforated cover from the plastic base. Remove the cover and insert the cable through the 9 mm hole, apply the base to the surface and screw with two screws or bolts. The length of the bolts or fixing screws for fixing should be chosen according to the thickness of the plastic base. Connect the power cable to the terminals in accordance with the “Wiring” section. Diagram: place the perforated cover on the fixed base and lock it by clicking on it. After installation and connection to the electrical measuring device, the sensor is ready for use. The sensor does not require any particular maintenance.
