accelerometer of the type a compensation of the effect of gravity and advantages of such a accelerometer

摘要

An accelerometer comprising a seismic mass (1) capable of being acted upon by a force induced by an acceleration to be measured. The seismic mass (1) is connected to a support (2) by a mechanical linkage (3) that can be bent by said force, and sensing means are provided for determining the acceleration from the force induced in the seismic mass. Compensation means are provided for compensating for the force exerted on the seismic mass by gravity. The mechanical linkage comprises, as the compensation means, at least one portion (4, 5) that mechanically biases the linkage against the force exerted on the seismic mass by gravity. A method for making said accelerometer is also disclosed.
