  • Patent number: 5869788
    Abstract: An electronic weighing device includes a lower electrically conductive plate, an upper electrically conductive plate, a load cell coupled to central portions of the upper and lower plates such that the load cell responds to weight on the upper plate, and a flexible, conductive band coupling the periphery of the upper plate to the periphery of the lower plate. An electronic circuit is coupled to the load cell. The circuit is provided on a board which is mounted on the lower plate close to its center. A pair of bores are provided in the lower plate extending from the circuit board to an edge of the lower plate. A pair of non-conductive rods are coupled to potentiometer on the circuit board. The non-conductive rods extend through the bores from the circuit board to the peripheral edge of the lower plate. The lower plate is provided with a shielded electrical socket which is coupled by shielded cable to the circuit board. A conductive cover is provided over the upper plate, the load cell, and the band.
