ABSTRACT OF THE INVENTION A digitally responsive electrostatic accelerometer having a pendulum pivotally movable about a hinge. A pair of torquer electrodes mounted on opposite sides of the pendulum are connected to a source of constant current. As the pendulum moves from its null position under the influence of acceleration forces, the displacement from null position is indicated by an increase in charge on the electrode which is in closer proximity to the pendulum. Electronic circuit means are provided to detect the direction of displacement of the pendulum from null and to apply a charge to the proper torquer electrode to force the pendulum back to null position. The principle of operation of the device is based upon the fact that the magnitude of the voltage on the torquer electrodes when charged from a constant current source contains information indicative of the position of the pendulum from null.
