The invention relates to a device for measuring accelerations by means of a change in the capacitance value of a capacitor (1) which is provided with two electrode plates (2, 3). According to the invention, the device is characterized in that the capacitor (1) comprises two fixed electrode plates (2, 3) and a dielectric body (4) which can be moved between the electrode plates (2, 3). The device according to the invention thus has two fixed, immovable capacitor plates (2, 3) between which a dielectric body (4) having a certain mass can move under the influence of an acceleration force (20). The distance between the electrode plates (2, 3) is constant owing to the measure according to the invention. The capacitance value changes linearly as a result of a dielectric body (4) being moved far or less far between the capacitor plates (2, 3) so that further processing of the capacitance value is comparatively simple. In addition, there is no risk of short-circuiting of the electrode plates (2, 3). |
