VARIABLE-CAPACITANCE FORCE-MEASURING TRANSDUCER Russian patent published in 2000 - IPC

FIELD: electrical measurement technology. SUBSTANCE: variable-capacitance transducer has electrodes positioned in separate insulated inserts secured on opposite walls of hole in horizontal plane of symmetry of block-body provided with upper and lower flexible members. Block-body has rigid side bases. One of bases has supporting surface for fastening of transducer, and other base is provided with surface for fixing on object being checked. Transducer with differential capacitor may be formed together with auxiliary electrode installed in parallel with main electrodes on insulated insert. Insulated inserts may be made in the form of two metal semirings embracing electrodes arranged on internal surface of semirings. External surfaces of rigid side bases for conveyor and bunker balances are of cylindrical shape, and they are provided with movable semirings and prismatic cover-plates. Auxiliary holes are made in flexible members for higher loads. EFFECT: higher accuracy of measurements. 8 cl, 10 dwg
