Abstract
A sensor plate for use in a load cell for use in an electronic scale comprising a planar first surface; a planar second surface opposite the first surface having a depression formed therein defining a flexure area; a load cavity formed in the second surface having a conical receptacle end for receiving a strut; and sensors disposed over the flexure area for generating a signal in response to a load applied to the loading cavity wherein the strut has a first conical projection end coupled to the conical receptacle end of the loading cavity and a second end coupled to a footer member such that the strut mechanically floats therebetween for providing the applied load at a substantially central position at the load cavity.
