STRAIN-GAGE WEIGHT METRE (VERSIONS) Russian patent published in 2011 - IPC G01G19/00 

FIELD: physics.

SUBSTANCE: proposed device comprises platform, strain-gage transducer, electromagnet, reference weight, ADC and microprocessor controller. Note here that movable platform is pivoted on side to support to weight position transducers arranged at preset distance between them. Second device comprises platform, strain-gage transducer, electromagnet, reference weight, ADC and microprocessor controller. Note here that platform moves vertically and is arranged at top part of open top box accommodating second horizontally moving platform pivoted on its one side. Said platform carries strain-gage transducer, electromagnet attracting reference weight, two limit transducers to define position of movable platform. Hinge joint support is linked with the device that provides for support horizontal travel for preset distance be means of, for example, cam made on motor shaft, while vertically moving platform thrusts upon the platform via movable supports, for example, balls.

EFFECT: higher accuracy of weighing.
