Abstract
A load cell comprises a member for receiving forces applied by the load, and a plurality of force sensing elements supported by the member and arranged with respect, to each other to independently sense differently directed components of the applied forces. The member is disposed, e.g., in a horizontal plane for receiving the load forces, and the force sensing elements are strain gages. One of the strain gages is arranged to sense a component of the forces applied in a vertical direction relative to the plane, and a second strain gage is arranged to sense a component of the forces applied in a horizontal direction relative to the plane. Among other advantages, the load cell is highly versatile can be used to measure loading forces applied in virtually any direction.
