Abstract
An electronic weighing device includes a lower base plate, an upper load bearing plate, and a load cell coupled to central portions of the upper and lower plates such that the load cell responds to weight on the bearing plate. The upper and lower plates are each notched at a central location, with the notches being offset from each other. The overlapping portions of the notches form a cavity for a central portion of the load cell, The load cell is tapered or reduced in height at opposite ends thereof so that its ends fit between a notched portion of one of the upper and lower plates and a full-thickness portion of the other of the upper and lower plates. The reduced height ends of the load cell are coupled to the upper and lower plates.
