Abstract
Load cell in which the magnitude of a force, such as the weight of a load, is determined by the stress produced in a bending beam to which the load is applied. A lever system permits the use of a thicker beam which results in highly accurate and repeatable readings even in load cells of relatively low capacity, e.g. less than 2 pounds. One embodiment has two load receiving arms connected to different points in the lever system to provide a dual capacity load cell.
