ABSTRACT:
In a scale wherein the force or load receiver is guided along a vertical path by a parallel guidance system having an upper and a lower plate, the lower plate cooperates with a recess in the lower part of the housing to form an air damper. Specifically, the lower plate of the parallel guidance system constitutes the piston of the air damper. For the scale with a capacitive sensor, the plate constituting the piston of the air damper is a metallic plate which also constitutes the movable plate of the measuring capacitor.
