ABSTRACT:
A pendulous accelerometer comprises a stator defining a cavity having two nfronting surfaces which constitute two electrodes.
It also comprises a pendulum consisting of a disc connected to the stator by a hinge. A servo-circuit applies DC forces to the capacitors, each comprising a surface of the cavity and the confronting electrically conductor surface of the pendulum for creating an electrostatic torque which balances the acceleration torque.
