High Accuracy Mass Measuring System Using Capacitive Mass Sensor

摘要

In the area of mass production, the products are weighted using load cell based weighting system. A load cell may be capacitive or resistive, is an uncontrollable weighing device. Improvement in filtering increases the speed of weighing and enhances the measurement accuracy. In this paper a new algorithm and architecture is proposed as weight filter for the weighing system with capacitive load cell. We verify and implement the novel algorithm in the measuring products successfully.
