ABSTRACT:
Apparatus for sensing the load on a platform without error caused by variations in the location of the load on the platform, including an integral sensor block comprising a double cantilever beam having one end attached to a fixed support and the opposite end supporting the platform. The beam is divided into upper and lower portions, each portion having two flexures spaced apart along the length of the beam portion. The flexures on the lower beam portion are spaced apart by a distance greater than the distance between the flexures in the upper beam portion. Strain gage resistance elements are bonded to the outer surface of the upper portion at the flexure.
