GAUGE FOR STRAIN-MEASURING BALANCE Russian patent published in 1998 - IPC

FIELD: electronic strain-measuring balances; mechanical value-to-electric signal conversion. SUBSTANCE: gauge has flexible element in the form of parallelogram provided with two rigid supports made as angles with mutually parallel vertical and horizontal shelves, three parallel flexible arms, and resistance strain gauges arranged on middle flexible arm. Vertical shelves of rigid supports are coupled to assembly of flexible parallelogram suspension by means of flexible arms. Horizontal shelves are arranged with overlapping of vertical shelf faces. Gauge has two auxiliary flexible elements positioned between rigid supports in symmetry with flexible parallelogram suspension. They are secured rigidly to supports. Auxiliary flexible elements have identical flexible characteristics, and their summary rigidity exceeds that of flexible parallelogram suspension. EFFECT: higher measurement results. 4 cl, 4 dwg
