ACCELEROMETER Russian patent published in 1995 - IPC

FIELD: instrumentation engineering. SUBSTANCE: base and sensitive element of accelerometer are made of one piezoelectric material and are interconnected by means of jumper to create pendulousness of sensitive element. Delay lines formed by interdigitated converters are arranged on both sides of jumper. Input converters are positioned on face surface of base and output ones - on sensitive element. Accelerometer has two torque motors placed on different sides of jumper. Ring coils of torque motors are anchored on sensitive element and their permanent magnets and magnetic circuits - on base. Accelerometers also has two formers of pulses of positive and negative polarity, reversible counter. EFFECT: improved operational stability. 4 dwg
