Load cells incorporating one or more gaged beams as the load sensing elements are compensated for off-centre loading in the longitudinal and/or lateral directions. The load cell may also include one or more flexure arms extending parallel to the beam 10). The relative position of the gages (13-16) and the neutral axis of the beam is made such that the gages (13-16) produce a correctible response to off-set loading by positioning the gages and/or physically altering the beam (10). Preferably, conventional or special strain gages are mounted upon the beam(s) to produce a correctible response by the gages by rotating and/or displacing them with respect to the longitudinal axis (18) of the beam (10). Resistors are then connected to certain of the strain gages to compensate for off-centre loading. The strain gages are advantageously placed all on one side of a beam but may be placed on opposite sides thereof. |
