Abstract
A force or weight measuring load cell arrangement of the planar gaged plate load cell type with bending beam members is made insensitive to the point of load application by bonding strain gages alternately on the top surfaces and on the bottom surfaces of bending beam members and shunting half-bridges by pairs of substantially equal resistors to reduce the errors caused by corner loading.
