PCT No. PCT/SE97/00404 Sec. 371 Date Dec. 23, 1998 Sec. 102(e) Date Dec. 23, 1998 PCT Filed Mar. 11, 1997 PCT Pub. No. WO97/35169 PCT Pub. Date Sep. 25, 1997A shear beam load cell comprising a cantilevered beam member (1) for measuring the shear force imposed on the beam member by the load (F) to be measured and one or more strain gauges mounted on the beam member so that they are affected by the deformation in the beam material. The free deflectable end portion (2) of the beam (1) has a section (10) with reduced material thickness, the upper side of this section being located substantially along the longitudinal neutral axis of the beam and defining a load application surface (11) for the load (F) to be measured. The load application surface (11) has a longitudinal extension, along the neutral axis or its extension, so that the point-of-load application for the load (F) to be measured can be moved along the load application surface in case of thermal expansions due to temperature variations in a tank, weighing container, foundation or the like. |
