PRESSURE TRANSDUCER Russian patent published in 2000 - IPC

FIELD: instrumentation, measurement technology for pressure measurement in gaseous, liquid and loose media. SUBSTANCE: pressure transducer has restoring member anchored on bearing member, three capacitive displacement transducers as minimum and power supply source. Capacitive displacement transducers can be connected to power supply source via switch individually or to inputs of differential amplifiers in pairs. Outputs of differential amplifiers are connected to analog-to-digital converters. Outputs of analog-to-digital converters are connected to computing-controlling device whose controlling input is connected to switch. EFFECT: enhanced precision of proposed pressure transducer during its long operation without any periodic calibration and provision for its matching with present-day information processing systems. 4 cl, 5 dwg
