Abstract
Abstract A force measuring apparatus with a mounting arrangement for incorporation between a force receiving plate and a base plate of a force measuring system. The force measuring apparatus has an axis extending substantially transversely to the force receiving plate and base plate and is provided with two force transmitting flanges having planar parallel mounting surfaces at the ends thereof. The flanges are arranged for receiving mounting screws for mounting the force measuring apparatus from the same side to both the force receiving plate and base plate and centrally with respect to the axis of the force measuring apparatus with the force measuring apparatus having force transmission surfaces thereof coinciding with the mounting surfaces.
