Summary:FIELD: measurement of linear acceleration of movement of object under any orientation of sensitive axis, measurement of acceleration of gravitational force in gravimetric devices. SUBSTANCE: rotor of gas- dynamic pylon and magnetic circuit of magnetic system of force transducer are manufactured as one unit from magnetically soft alloy. Differential photoelectric position pickup is manufactured spaced apart along axis of accelerometer and has two pairs of photodiode - light-emitting diode and two pairs of immobile-mobile shutters. Internal space of accelerometer is divided into two equal gas spaces interconnected by hole. Asynchronous electric motor to rotate rotor of pylon has two spaced apart stators, two hollow rotors and two rings fabricated from magnetically soft alloy. Rings are mounted in symmetry in each of spaces. Mobile shutters and hollow rotors are manufactured as integrated pieces. EFFECT: high prolonged stability and small drift of zero. 2 dwg
