  • Low pressure transducer
    Patent number: 4545255
    Abstract: A transducer is provided for measuring very low pressures, on the order of 1.5 inches of water. A fluid-tight elastomeric barrier formed with convolutions to allow relatively large linear deflections is bonded to stiff sensing element of minimum mass, the deflection of which is sensed by strain gauges mounted on a neck connecting the sensing element to the transducer housing.
