PRESSURE STRAIN GAGE TRANSDUCER Russian patent published in 2004 - IPC

Abstract RU 2237873 C2

FIELD: measurement technology; measurement of pressure of liquids and gases.

SUBSTANCE: proposed strain gage transducer includes flat square membrane made from monocrystal silicon with longitudinal and transversal resistance strain gages; membrane has different thickness: thickness at edges exceeds that in center; resistance strain gages are located on part having greater thickness.

EFFECT: increased output signal of pressure strain gage transducer.
