CAPACITY INDICATOR OF EXCESSIVE PRESSURE Russian patent published in 2005 - IPC

Abstract RU 2258913 C2

FIELD: aircraft equipment engineering.

SUBSTANCE: device has body with connecting pipe and membrane, capacity converter, including standard capacitor and measuring capacitor. In upper portion of indicator body additional membrane is positioned, geometric dimensions of which are identical to geometric dimensions of membrane, positioned in sensor body. Both membranes are interconnected by rod, passing along axes through apertures of moving and standard capacitors. Fixed electrode is rigidly connected to standard capacitor while providing for their electric insulation from body using glass bushings. By its outer end it forms a facing of moving capacitor, second facing of which is held on rod. Threaded bushing-stop carries inside elements of moving and standard capacitors, and its end preserves membrane from effect of overload pressure. Inner hollow of indicator is vacuumized, and in a lid aperture is made, connecting above-membrane hollow of additional membrane with atmosphere.

EFFECT: use of two similar membranes, connected along axis by rigid rod, to provide for compensation of temperature error of indicator and concurrently provide for linearity of its characteristic.
