ABSTRACT:
An accelerometer comprises a pair of stators, a permanent magnet arranged within each of the stators, arcuate support portions diametrically opposed to each other on the surface of each stator, a pair of ring members each of which is positioned on the arcuate support portions of a stator, and a support ring with a flapper interposed between the support ring members. The flapper is connected to the supporting ring by two hinge portions. On each side of the flapper is a bobbin on which a coil is wound, the coils being connected to an external circuit. All of the component elements of the accelerometer are constructed and designed so as to avoid stress depending upon a change in ambient temperature.
