PICKUP FOR TENSOMETRIC BALANCE Russian patent published in 1997 - IPC

FIELD: measurement technology. SUBSTANCE: pickup for tensometric balance includes two identical power units placed vertically and rigidly coupled in series opposition. Each power unit has two power arms joined by three parallel restoring girders forming parallelogram suspension and resistance strain gauges put on center girder. Power arms of each unit are L-shaped. Lower arm of upper power unit and upper arm of lower power unit are manufactured as one unit. Ends of center restoring girder are placed into grooves made in vertical flanges and are anchored on lower walls of grooves. Power arms have limiters of vertical movements located between face of vertical flange and opposite surface of horizontal flange and forming clearances which can be filled with liquid with low pressure of vapors in which capacity silicon-organic fluid can be used. EFFECT: simplified design, enhanced functional reliability. 6 cl, 3 dwg
