FIELD: measuring equipment.SUBSTANCE: piezoelectric transducer has bending touch panel, made of elastic thin-film substrate elastic polymer, two foil strain gauges planar located on opposite sides of substrate, longitudinal axes of which are parallel to each other, or four foil resistance strain gauges, planar and in pairs located on opposite sides of substrate, longitudinal axes of which are symmetric about its longitudinal axis and parallel to each other. Strain gages are connected in adjacent arms of semi- or full-bridge measurement bridge circuit. Touch panel is oriented perpendicular to vector of applied force. In transducer introduced circular segment with curved surface corresponding to maximum possible elastic bending of sensor console, honeycomb, and drag element. Circular segment has permeable surface.EFFECT: wider dynamic range of conversion of stress-deformed state sensor console due to action on its surface velocity head (dynamic pressure) gas or fluid flows.1 cl, 2 dwg |
