Increasing the stability and accuracy of electronics scales for indastrial weighing

Abstract

The paper considers the issues of applying a mathematical model of a strain signals sources as a two-oscillatory system with demoing. Types of strain signals corresponding to the operating and emergency modes of strain gauges in weighing platforms were found. Synthesised algorithms for dynamic interference suppression with adaptation of the analog-to-digital converter to their characteristics by envelope transformations and processing of a plurality of pairs of strain signal samples of distant half-periods of the obstructed. А synthesis method has been developed based on the stability criterion of the optimal ADC structure with out a tendency’s to self-excitation with an ultimates increase in resolution and speed. Eliminates the need for any adjustment of the ADC to the characteristics of dynamic interference at the operating site.
