  • Method and apparatus for monitoring fluid pressure
    Patent number: 7526961
    Abstract: A method and apparatus for monitoring the pressure of a fluid within a rigid vessel are disclosed. A preferred method comprises monitoring the capacitance of a capacitor comprising a deformable resilient solid dielectric separating first and second conductive elements, the capacitor being exposed to said pressurised fluid such that the distance between the conductive elements and thus the capacitance of the capacitor changes with compression or relaxation of the dielectric in response to changes in fluid pressure.
    Type: Grant
    Filed: July 26, 2007
    Date of Patent: May 5, 2009
    Assignee: Air Products and Chemicals, Inc.
    Inventors: Neil Downie, Mathilde Pradier
