ABSTRACT:
A load cell having a self-contained overload protection system for preventing the load cell from being loaded beyond its rated capacity, wherein the load cell includes fixed and movable end constraints in spaced relation, upper and lower flexures between the constraints, a sensing beam coacting with the constraints and flexures and having means for sensing stresses, a cantilever beam extending from one of the end constraints coacting with the cantilever beam to prevent the load cell from exceeding its safe overload range.
