A load sensing system having at least one load sensing assembly for use with a weigh frame, each assembly including at least a first lever and a second lever. Each lever has a lever longitudinal axis, a lever fulcrum section, a lever load section, and a lever connector section spaced from the lever fulcrum section and the lever load section along the lever longitudinal axis. For each lever, a flexure plate is aligned in parallel with the lever longitudinal axis and has a middle bearing portion and opposing end portions with one of the end portions fixedly attached to its respective lever. Each lever fulcrum section has a lever bearing surface including one of (i) a line-of-contact rounded bearing edge oriented perpendicular to the lever longitudinal axis or (ii) a flat bearing face. The lever bearing surface of each lever touches the middle bearing portion of the flexure plate. Each assembly further includes a sensor having a support surface, a force transmission platform, and an output representative of total force applied to the force transmission platform. At least one force transmission link is adapted to connect each lever connector section to the force transmission platform, and at least one load link is adapted to connect the lever load section of each lever to the weigh frame.
