Patent ID: 7275452

Claim:
A beam load cell of the type having a first stationary member and a second moveable member with a beam positioned therebetween, such that when a force is applied to said moveable member in either a push or pull direction, said beam is moved in the direction of the force and exerts force on said first stationary member, said beam having located on the surface thereof at least one force responsive sensor and for an undesirably large force said beam can rupture, in combination therewith a stop member to limit the movement of said moveable member for a large force applied to the cell in either a push or pull direction and therefore, to prevent breakage of said beam, comprising: a longitudinal tubular member surrounding at least said second member, and means located on the inner surface of said tubular member to coact with said second member for limiting the distance said second member travels upon application thereto of a push or pull force.
