Abstract:
A pressure transducer system includes a housing with a chamber, a member with a stored electrical charge, and a pair of electrodes that are at least partially in alignment with each other. At least a portion of the chamber is at a reference pressure. The member is connected to the housing and extends across at least a portion of the chamber. Each of the pair of electrodes is connected to the housing and is spaced from and on substantially opposing sides of the member. The member is movable with respect to the pair of electrodes or one of the pair of electrodes is movable with respect to the member in response to a monitored pressure.
A high resolution optical electronic measuring device for measuring displacement distance between an object which moves and one which is generally stationary includes apparatus for generating a series of cyclic radiation fringe patterns moving in correspondence with the object being observed and electrical circuitry for processing two corresponding cyclically generated electrical signals to provide increased measurement resolution by electronically multiplying each division on a measuring scale into eight measurement increments.
