An H-slit type beam (double beam type load cell) has an effect on increasing the strain signals. It can help to enlarge the sensitivity of a force sensor while keeping enough rigidity and stiffness. The other characteristic of an H-slit beam is that its deformation pattern is same as that of a four bar link mechanism. For this kind of mechanism, it is highly important to show resistivity to torsional deformation forces. Commercial weighting equipments utilizing this type of load cell is expected to be capable of eliminating the error due to off-center loading. The effectiveness of it is believed to be the similarity between its structure and a Roberval balance mechanism. However, the moment canceling mechanism involved in it has not been made clear. This paper investigates the error eliminating ability of an H-slit beam and a single beam structure when exerted by an off-center load through FEA model.
