  • Patent number: 7290453
    Abstract: A pressure sensor assembly comprised of a single and dual layer diaphragm with integrated force sensing flexure, such as a cantilever beam. Strain gages are positioned on the force sensing beam. The pressure forces the diaphragm to deflect. The deflection is constrained by the beam, which is compelled to bend. The bending induces strains in strain gages located on the beam. The strain gages are connected in a Wheatstone bridge configuration. When a voltage is applied to the bridge, the strain gages provide an electrical output signal proportional to the pressure. Composite diaphragm—beam pressure sensors convert pressure more efficiently and improve sensor performance.
