Device for detecting force effect resulting from burglary or break-up attempts on e.g. window, has sensor fixed at frame and/or at wing, where resistance of sensor changes during deformation resulting from force effect in window and/or door

摘要

The device (1) has an extension measuring sensor (1.1) e.g. strain gauge strip, fixed at a frame and/or at a window wing or a door wing, where electrical resistance of the sensor changes during deformation of the frame and/or the window wing or the door wing. The deformation results from force effect in a window and/or in a door. The sensor longitudinally runs to a boundary area of the frame and/or the window wing or the door wing. The sensor is fastened to the frame and/or the window wing or the door wing in a circulating manner. The device comprises a layer made of plastic and/or lacquer and applied on a view side of the extension measuring sensor.
