Abstract
A load cell for sensing forces or moments with respect to an orthogonal coordinate system includes a load cell body and a plurality of sensing circuits. The load cell body includes a rigid central member, a rigid annular ring and a plurality of radial members extending radially and joining the central member to the annular ring. A plurality of sensing circuits are mounted to the plurality of radial members. Each radial member includes a first sensing circuit providing a first output signal responsive to a first force exerted between the central member and the annular ring through the corresponding radial member in a first direction. Each radial member also includes a second sensing circuit providing a second output signal responsive to a second force exerted between the central member and the annular ring through the corresponding radial member in a second direction, wherein the second direction is substantially perpendicular to the first direction.
