ABSTRACT:
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 .sub.E - .sub.M : .sub.M to the thickness of the spacers insulating the electrode plates from the metallic casing, .sub.E corresponding to the thermal expansion coefficient of the spacers and .sub.M to that of the metallic casing.
