The room sensor consists of a housing, a printed circuit board, connection terminals and a measuring tip. The two-part housing comprises a base and a screwed removable cover. A rubber seal is installed between base and cover in order to satisfy the requirements of IP 65 degree of protection. The measuring circuit and the setting element are accommodated on the printed circuit board inside the cover, the connection terminals in the base. Housing and measuring tip are screwed together. The measuring tip features a degree of protection of IP40. The sensing elements are located at the end of the measuring tip, protected by a screw-on filter cap. Cable entry is made via the cable entry gland M16 supplied with the sensor, which screws into the housing. If the sensor is used outdoors, that opening must be closed off and the prepared hole on the opposite side of the base knocked out.
