1. A load sensing system comprising 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 having 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 aligned in parallel with the lever longitudinal axis, the flexure plate having 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 touching the middle bearing portion of the flexure plate;
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 adapted to connect each lever connector section to the force transmission platform; and
at least one load link adapted to connect the lever load section of each lever to the weigh frame.
