LOAD CELL WITH HYDRAULIC CENTERING DEVICE

摘要

The invention relates to a load cell with a centering device which improves the force transmission within a load cell, wherein the centering device has the following features: in the deformation body (2), there is provided a cylindrical recess (5) in which there is arranged a force-introducing punch (6) that is in point contact with the floor of the cylindrical recess. The circumferential section (6b) of the force-introducing punch (6) is convex. This section (6b) forms, with the wall surface (5b), an annular gap (7) of width (a) between 0.05 mm and 0.45 mm. The annular gap (7) is at a predetermined distance from the floor surface (5a). A liquid fill (8) is provided in the recess (5). An elastic cover (9) is arranged over the liquid fill (8).
