For the measurement of accelerations, e.g. gravitation components for goniometry, in the oscillating circuit of two RC oscillators capacitors are provided, which in a common, metallic casing between two electrode plates (2,3) have a spring-elastically held, common, circular deflection part. In order to avoid dielectric interference, the electronic means are arranged on one side of the instrument, are surrounded by a metallic cover and their electrical connection to the more remote electrode plate takes place by a wire, which is passed in contact-free manner through a central hole in the circular deflection part and the closer electrode plate. The spacing between the deflection part and the electrode plates remains constant in the case of a non-deflected deflection part, in that its size forms a ratio E- M: M to the thickness of the spacers insulating the electrode plates from the metallic casing, E corresponding to the thermal expansion coefficient of the spacers and M to that of the metallic casing.
