| Abstract: | A hybrid quantifying is a new method with high speed and precision, which is widely applied in quantifying packaging for powder and particle materials. One of the keys in hybrid quantifying is how to weigh with a high speed and precision. In the paper we analyzed the mechanical characteristic and the loading wave of a weighing system, discussed the selection of weighing sensor, the application of parallel connection and summation circuits, filter circuit, A/D conversion and microcomputer, and the techniques of data sampling and processing. In order to rapid and accurate acquire the feed weigh, we also analyzed the experiments of quantifying. The results showed that the techniques of data sampling and processing were effective and could meet the demands of rapidity and precision in hybrid quantifying. |
