STRAIN-GAUGE TRANSDUCER OF DYNAMIC PRESSURE Russian patent published in 1995 - IPC

FIELD: instrumentation. SUBSTANCE: strain-gauge transducer of dynamic pressure includes cylindrical case, round membrane made fast to it, two mirror-symmetric beams with resistance strain gauge rigidly attached to membrane at angle α. Ends of beams are anchored in case and their other ends are positioned on membrane at distance r from its center. Value r is related to angle a by dependence specified in description of invention. EFFECT: increased accuracy of measurement of dynamic pressure which is exhibited in low nonlinearity of characteristic of dynamic pressure, enhanced dynamic sensitivity. 4 dwg
