MULTIRANGE PRESSURE TRANSDUCER Russian patent published in 2004 - IPC

FIELD: measurement technology; measurement of pressure of liquid and gaseous media. SUBSTANCE: proposed transducer is additionally provided with membranes with strain gauges rated at different maximum pressures. Extreme additional membrane rated at minimum pressure range separates hermetically pressure being measured from reference pressure delivered to all remaining membranes. Transducer is also provided with analog signal switch for connection of strain gauges with micro- controller through analog-to-digital converter. EFFECT: enhanced sensitivity and accuracy of transducer in wide range of measurements. 5 dwg
