Abstract
An accelerometer includes a seismic mass which is subjected to a force when accelerated. The seismic mass is connected to a support by a mechanical connection which can bend under the influence of the force. A detector is provided to determine the acceleration induced in the seismic mass by the force. Compensation can be provided for the force exerted on the mass due to gravity. The mechanical connection includes at least one component which provides compensation and induces in the mechanical connection a prestress counteracting the force exerted on the mass by gravity.
