COMPENSATION ACCELEROMETER Russian patent published in 2002 - IPC

FIELD: measurement technology; linear acceleration information transducer. SUBSTANCE: accelerometer has body, first plate having movable and immovable parts with flexible strips connecting them, differential capacitance-type position converter with fixed electrodes on second plate, moving-coil power converter with permanent magnet and compensating coil and amplifier. Compensating coil is mounted on four weights whose configuration follows configuration of compensating coil. Second plate has straight sides located at distance from weights determined through calculations. Height of weights, sizes of gaps between movable and immovable parts exceed clearance in differential capacitance-type converter by at least by order. EFFECT: enhanced accuracy of measurement. 4 cl, 4 dwg
