Compensation pendulous accelerometer

A compensation pendulous accelerometer comprises a body in which a pendulous unit is positioned that is made as a unitary plate of a silicon monocrystal and comprises a movable vane on a flexible suspension and a support frame with protrusions. Two magnetic systems are secured on opposite sides of the movable vane and two coils of a torquer are positioned in a clearance of a corresponding core and are secured on a corresponding side of the movable vane. The flexible suspension includes flexible members arranged at an angle of 90 degrees relative to one another, symmetrically relative to an axis of symmetry of the pendulous unit. When the accelerometer is accelerated, the movable vane deflects in the opposite direction of the acceleration, and a current in the coils returns the movable vane to its initial position. A measured amount of current through coils is used to determine the acceleration.
