  • Thin disk force sensor and method of making
    Patent number: 5297430
    Abstract: A thin disk force sensor having measuring elements of not more than five layers including force introducing layers welded under preloading to a thin disk housing. The measuring elements, weld and disk housing are planarized. A vapor deposited layer is selectively applied to the force measuring elements to increase the applied force compared to the housing.

  • Monitoring system for cyclically operating machines
    Patent number: 5179857
    Abstract: Monitoring systems for cyclically operating machines having a cylinder including sensor to be mounted on the exterior of said cylinder for detecting both force in said cylinder and structure-borne signals in the cylinder; and having a computer for storing pre-recorded force and structure-borne noise signal as a function of time in a cycle and for comparing said detected and pre-recorded force and structure-borne noise signals to determine the status of said machine. The sensor has the form of a thin disk fitted between a cylinder cover and a nut of a cylinder cover stud under preload, thus replacing the standard washer.
