GEAR MEASURING PRESSURE Russian patent published in 1998 - IPC

FIELD: measurement of distribution of pressure pulsations on surfaces of aircraft under conditions of flight in upper layers of atmosphere under high values of difference of potentials emerging on surfaces. SUBSTANCE: structure of transducer is supplemented with additional screen 3. Thin-film capacitive transducer is attached to surface of article by means of current conductive adhesive 2. Gear is protected against external noise and common-mode interference. High-resistance capacitive output of transducer is converted to low-resistance one with use of charge amplifier 16 that is provided with two protective screens 17, 18. Gear incorporating capacitive transducer is polarized by voltage source 15 of direct current. EFFECT: improved functional authenticity of gear. 1 dwg
