Weight sensor for electronic scale, having force transmission elements arranged symmetrically to vertical, centre axis plane proceeding through coil carrier and load reception

摘要

The sensor comprises a movable load reception (10) led through parallel guide elements at a stationary base body (1) of a material block, and several force transmission elements (10, 11, 12, 13 to 34, 38, 38', 42, 43, 44, 46, 55, 57, 58,62) arranged in series between this, a coil carrier (28), and the base body. The coupled, individual force transmission elements are arranged symmetrically to a vertical, centre axis plane proceeding through the coil carrier and the load reception, and are likewise element of the material block. A protruding part (2, 3) of the base body extends partially between geometrically spaced transmission elements, and forms support- or bearing points (4,4'; 5,5') for a part of the force transmission elements.
