ABSTRACT:
A weighing system having a base region (1), a parallel-guided load receiver (4), at least one transmission lever (2) that is pivotably mounted on the base region via at least one flexural pivot (3), and a coupling element (7) that connects the load sensor to the short lever arm of the transmission lever. The flexural pivot (3), at least one part of the transmission lever (2), and at least one part of the base region (1′) are monolithically formed from a block. The flexural pivot (3) is separated from the rest of the block, and at least one spring connecting segment (36/35/38, 37/35′/39) of the flexural pivot (3) includes two spaced-apart thin material points (36, 38; 37, 39). In this way, a hysteresis-free flexural pivot can be created without the need for separate assembly components.
