  • Overload protected pressure transducer
    Patent number: 4543832
    Abstract: A liquid filled pressure transducer which utilizes a self activating lip seal type valve to create a sealed cavity within the transducer to prevent the flow of liquid from behind the pressure diaphragm and thereby prevent distortion of the diaphragm under overload conditions. A mechanical stop prevents excess displacement of the sensor element.

  • Strain gage load cell
    Patent number: 4148219
    Abstract: A column type bonded strain gage load cell having improved linearity and output is achieved using a column having a pair of opposed transverse bores which create a web therebetween. The web has a relatively high strain as compared to the circumferential strain of an unbored column. Strain gages bonded to the web, in combination with strain gages bonded at selected regions on the column provide improved linearity and increased output.

  • Parallel beam load cell insensitive to point of application of load
    Patent number: 4128001
    Abstract: A parallel beam load cell wherein sensitivity to transverse load position changes is reduced by changing the shape of one of the beams in the vicinity of one strain gage element whereby the neutral axis of said beam is changed with respect to said strain gage element. Longitudinal load position sensitivity is reduced by changing the cross sectional area of one of the beams adjacent one strain gage element.
