MEASURING DEVICE Russian patent published in 1998 - IPC

FIELD: measurement technology; geophysics; geodesy. SUBSTANCE: measuring device has body, inertial mass, three mechanical couplings of inertial mass with body separated in plane through 120 deg., three electronic circuits included along with mechanical couplings in three force-to-electric signal transducers and computing unit. Every mechanical coupling is made as inertial mass support. It is positioned on base of body at acute angle to device vertical axis of symmetry. Mechanical coupling includes photoelastic element of force-to-light intensity piezooptical transducer which is also provided with light source, polarizer, analyzer, and phase plates. Electronic circuit is made as photoreceiver mounted at output of force-to-light intensity transducer, and amplifier. EFFECT: higher sensitivity of device. 4 dwg
