Pressure-sensitive sensor device for a danger signal transmitter

摘要

A pressure-sensitive sensor device for a danger signal transmitter having an element that can be deflected by pressure variation, in particular a diaphragm 11, by means of which a movable contact 12 is moved onto a fixed contact 13 or 14 of a first electrical contact maker for the purpose of emitting a danger signal, and having an airtight pressure chamber which is at least partially covered by the diaphragm 11 and is connected to a space 17, e.g. a pane interior between double panes of a window, which is to be monitored and has a specific gas pressure, a second contact maker 2, 3, 4 being arranged in the pressure chamber 5, 6 and having a movable contact 2 which can be pressed against one of its fixed contacts 3, 4 by a slight pressure variation in the pressure chamber, and the pressure chamber 5, 6 being sub-divided by a partition 7 which actuates the movable contact 2 of the second contact maker into two pressure chambers 5, 6 between which a gradual pressure compensation takes place, and the connection 8 to the space 17 to be monitored opens into one of the two pressure chambers 5, 6 (Fig. 1). <IMAGE>
