ACCELEROMETER Russian patent published in 2012 - IPC G01P15/13 

FIELD: instrument making.

SUBSTANCE: accelerometer comprises a movable plate - a pendulum 1 on an elastic suspension 2. On the pendulum there are coils 3 of torque sensor fixed, and on the stationary part there are magnets 4 and polar tips 5, at the same time inserts 6 from permalloy are fixed to the ends of the magnets. Between the insert 6 and the main magnetic conductor 8 there is a circular air gap 9. In the main (working) gap 10 formed by the magnetic conductor 8 and the pole tip 5 there is a coil 3 of the torque sensor. The gap between the pendulum and fixed parts of the magnetic conductor (side plates) is ensured with the help of three mounts (ledges) 11 at each side of the support ring of the central quartz plate. Damping gas is helium, and aluminium inserts are introduced between the elastic suspension and the magnetic conductor.

EFFECT: increased heat release and higher accuracy of zero signal and reliability of accelerometer's operation.
