PIEZORESONANCE FORCE TRANSDUCER Russian patent published in 1994 - IPC

FIELD: measurement technology. SUBSTANCE: transducer has a housing flexible member in the form of envelope of revolution rigidly and sealingly fixed to the housing by edge, two-arm beam rigidly and sealingly attached to the flexible member along its axis, strain-gauge piezoelectric elements first ends of which are secured to the housing and the other ones are secured to the arm of beam extending to a sealed cavity of the transducer. The transducer is characterized in that a sensitivity axis of the piezoelectric elements is oriented along a vector of force to be measured. The envelope of revolution can be made in the form of a flat round plate or can be conically or spherically shaped. EFFECT: enhanced sensitivity, accuracy. 3 cl, 3 dwg
