Abstract: A portable weighing scale assembly which is comprised of a base structure including a double ended shear beam load cell structure. The shear beam load cell structure has top and bottom brace members and a spacer plate located at its center position and to which the load platform is mounted. The ends of the load cell structure are mounted to a support saddle and strap which are fixed to opposing base members of the base structure.

Abstract: A double ended shear beam load cell assembly providing a structural weight bearing component for a portable, low profile weighing scale. The load cell has an elongated rectilinear beam structure with a pair of aligned and laterally opposing apertures which define internal, spacially parallel end walls adjacent the ends of the beam. Strain gauges are mounted in a predetermined orientation on the aperture end walls of the beam. Top and bottom brace plate members and a spacer plate are mounted to the central portion of the beam. The load cell beam ends are further provided with structure for mounting in a weighing scale base.
