METHOD DETERMINING PULSATIONS OF PRESSURE AND CAPACITIVE PRESSURE TRANSDUCER FOR ITS IMPLEMENTATION Russian patent published in 1997 - IPC

FIELD: measurement technology, measurement of distribution of pressure pulsation on surface of easily deformed articles. SUBSTANCE: pressure transducer has several sensitive elements. One group of sensitive element is intended for measurement of influence of determination. Second group is positioned in symmetry above first group of sensitive elements and is passed over by gas stream. First and second groups of sensitive elements are placed in symmetry and uniaxially in the form of package to register pressure. Transducer has seven metallized and nonmetallized films. Proposed method of measurement of pressure pulsations makes it possible to isolate deformation signal from key pressure signal. Package of transducer is bonded on to surface of article. EFFECT: increased functional reliability of method and device. 2 cl, 1 dwg
