Abstract
A monolithic weighing system including a base (12), a load holder (26), which is articulated on the base (12) through a parallel link arrangement (16, 20), and a lever (28), which is articulated on the load holder (26) and which has an attachment point for a force compensating arrangement and a target area (32) for an optical position sensor (34). The target area (32) has a slotted diaphragm (36) in a thin walled lever section of the lever (28) in the deflection plane thereof. A position sensor pedestal (38a, b), which is integrally connected to the base (12), is arranged laterally adjacent to the target area (32). The position sensor pedestal has a pedestal aperture (40a, b), which extends perpendicularly to the deflection plane. The slotted diaphragm (36) of the target area (32) is laser-machined through the pedestal aperture (40a, b).
