ELECTRONIC STRAIN-SENSITIVE SCALES Russian patent published in 1995 - IPC

FIELD: measurement technology. SUBSTANCE: device has weight measuring module having removable trays for placing loads to be weighed. The weight measuring module has casing with cover, inside which weight-measuring unit is mounted. It has weighing platform with fastening members, base and rigid force measuring frame consisting of two force beams placed in parallel to each other and force bearings, each of which has the upper and lower arms of force and force cell positioned between them represented by parallelogram-like elastic member with resistance strain gauges. Longitudinal axes of force beams belong to the vertical parallelogram-like elastic members symmetry plane. The lower longitudinal force beam is attached to the base by means of two supporting members directed in perpendicular to each other and placed at its opposite ends. Fastening members of the weighing platform are located on the end portions of the upper force-transmitting longitudinal beam adjacent to the weighing bearings. EFFECT: enhanced accuracy in determining weight of articles. 3 cl, 6 dwg
