Load washer transducer assembly

摘要

A load washer transducer assembly includes a cylindrical housing symmetrically disposed about a given axis and having a longitudinal central aperture extending from a top to a bottom surface. The loop and bottom surfaces each have a peripheral flange coaxially located with respect to the aperture. The major surface of said cylinder includes a narrow slot located relatively centrally and coaxial with the aperture. A thin metallic shim is coupled to the housing and positioned across the slot and has mounted thereon a sensor element to monitor a pressure applied to one of said surfaces as concentrated mainly about said associated flange. In a typical load cell, another thin metallic shim is coupled to the housing and positioned across the slot and along the same diameter as the above noted shim. This shim also has mounted thereon a sensor element. The two sensors mounted diametrically opposite on the housing and across the slot serve to provide compensation for bending moments which may be induced by off-center loads. Other embodiments which employ more than two shims and associated sensors are also disclosed.
