Multi-axis load cell

A load cell for sensing forces or moments with respect to an orthogonal coordinate system, the load cell comprising:

• a load cell body including:
• 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, wherein each radial member includes:
• a first sensing circuit formed only of a first set of sensing elements on the corresponding radial member and 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 and
• a second sensing circuit formed only of a second set of sensing elements on the corresponding radial member and 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.
