  • Patent number: 4512432
    Abstract: There is disclosed an accurate and relatively inexpensive electronic scale. A parallelogram linkage is provided having one link stationary and secured to or formed integral with the scale housing. A cantilever sensing beam has bonded strain gauges on the tension and compression sides of the beam, the cantilever beam accomodating deflection within its elastic range related to the applied force. The stationary end of the cantilever beam is secured proximate the stationary end of the parallelogram linkage. The free end of the cantilever beam is connected to the link of the parallelogram linkage opposite the fixed or stationary link by flexible coupling member to constitute a compact weight transducing system. The strain gauges are connected in an electrical bridge circuit to provide an electrical analog signal that is an accurate measure of the weight of the postal article and an analog to digital converter is controlled by a microprocessor which also controls the keyboard input and display functions.
