Load cells incorporating one or more gaged beams as the load sensing elements are compensated for off-center loading in the longitudinal and/or lateral directions. The load cell may also include one or more flexure arms extending parallel to the beam. The relative position of the gages and the neutral axis of the beam is made such that the gages produce a correctible response to off-set loading by positioning the gages and/or physically altering the beam. 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 of the beam. Resistors are then connected to certain of the strain gages to compensate for off-center loading. The strain gages are advantageously placed all on one side of a beam but may be placed on opposite sides thereof.
