Zusammenfassung: | acac1naeA method and an apparatus for dynamically checking the weight of objects (-) which are guided across a weight-sensitive zone of a weighing device at an adjustable conveying rate by a conveying mechanism (-). At regular intervals, the weight-sensitive zone supplies individual measured weight values (E, . . . , E) from which resultant weight values are derived in a digital evaluation unit by averaging. The evaluation unit includes a plurality of cascaded averaging filters (-) which have different filter lengths that are varied by a common scaling factor depending on the conveying rate. |
