  • Patent number: 4009604
    Abstract: Pressure converter for use between a hydraulic load sensing element and a gauge or other device to indicate a property of the load directly in desired units. The pressure converter comprises a first force-pressure transducer connected hydraulically to the sensing element, a second force-pressure transducer connected hydraulically to the gauge, and a pivotally mounted beam having first and second arms connected to the transducers for producing a pressure in the second transducer corresponding to the pressure from the sensing element and the relative lengths of the arms. In one embodiment, the beam pivots about an adjustable fulcrum member which can be moved axially of the beam to vary the lengths of the arms and provide the desired calibration. In a second embodiment, the pivot for the beam is provided by a flexure plate, and the lengths of the arms are adjusted by changing the distances between the load cells and the flexure plates.
