ABSTRACT:
In a weighing scale including a load receiving member (2) being elastically deflectably guided by virtue of a parallel guide mechanism (3, 4) is provided an electromagnetic compensating system (12, 13, 16) for detecting the deflection which is proportional to the load. In order to achieve high precision and a simple construction, a lever (6) being located between said compensating system and said load receiving member (2) is supported on an elastic member (11), thereby preventing any positional changes in the compensating system or any non-homogeneity errors associated therewith (FIG. 1).
