COMPENSATING ACCELEROMETER Russian patent published in 1995 - IPC

FIELD: measurement technology. SUBSTANCE: compensating accelerometer is meant for measurement of linear acceleration in navigation. It has inner 6 and outer 7 parts of one plate 5 coupled with restoring jumpers, capacitive position pickup, magnetoelectric power converter with ring compensation coil 11 and permanent disc magnet 10 of diametrical magnetization. Immobile part 6, mobile part 7 and restoring jumpers are manufactured as one element from monocrystalline silicon. Boards 8 with electrodes 9 of position pickup are mounted on immobile part 6, four weights are put on mobile part 7. Three weights with different density of material are placed on one side at angles of 120 deg from each other. Compensation coil 11 is positioned on them. Masses of weights and compensation coil 11 and their positions with reference to axis of suspension are such that moment acting on mobile part 7 along one axis of accelerometer is equal to zero and differs from zero along measurement axis of accelerometer. EFFECT: enhanced precision of measurement of linear acceleration. 4 cl, 6 dwg
