ACCELEROMETER OF COMPENSATION TYPE Russian patent published in 2002 - IPC

FIELD: measurement technology. SUBSTANCE: device has the first plate having movable cantilever member, the second and the third plate having movable differential capacity-type converter electrodes, two-phase voltage generator of alternating current, direct current reference voltage power supply source and amplifier with two antiphase outputs. The first movable cantilever member is made in the internal part of the first plate. The second movable cantilever member is made in the internal part of the first member the free cantilever side of which is opposite to the free cantilever side of the first movable member. The fixed electrodes are mounted in the area of the projection over the second and the third plates of the movable member. The movable differential capacity-type converter electrode mounted on the second movable member is connected to the direct current reference voltage power supply source. EFFECT: higher upper limit of measurable accelerations; higher accuracy of measurement. 6 cl, 4 dwg
