ABSTRACT:
A weight scale including: a measuring electronic circuit including a filter; a load cell attachable to a support housing and generating a load signal processed by the filter of the electronic circuit; a spring coupled to the load cell to apply a force to the load cell, wherein the load signal is indicative of the force, and a scale beam connected to the spring and to the support housing, wherein a weight to be measured is attached to the scale beam and the force applied by the spring is indicative of the weight, and wherein natural frequencies of the weight and spring is higher than a cut-off frequency of the filter.
