Abstract
A load cell having overload protection wherein a central cantilever beam is provided between the sensing beams in the load cell structure and is bounded by slots of narrow gap width. When an excess load is applied, the load cell structure is deformed and contacts the cantilever beam to transfer the load thereto. The gap width determines the amount of applied load which initiates the protection.
