DEVICE FOR FORCE MEASURING Russian patent published in 1997 - IPC

FIELD: instruments. SUBSTANCE: device has electric oscillator, two parallel piezoelectric elements which have three outer plates, one of which is connected to oscillator and other are connected to signal comparison unit which is connected to measuring instruments. In addition device has force-transmitting members. Two piezoelectric elements are acoustically connected through connection members on which is of immersion type and is designed as thin liquid layer which is located between piezoelectric elements. Area of contact between piezoelectric elements through immersion element is proportional to level of force to be measured. EFFECT: increased functional capabilities. 1 dwg
