Abstract

The vibration detector has a detector element, an inhibition device, an electronic element which processes the data emanating from the detector element and the inhibition element, and an actuator which controls an audio or visual warning device. The detector transforms acceleration variations corresponding to vibrations into an electric signal which is transmitted to the electronic element, if the inhibition device is passing, and which drives the actuator and the warning device if the amplitude of the signal exceeds a pre-adjusted level.
