Study on the Dynamic Quantitative Weighing System Based on the Buoyancy Weighing Sensor

摘要

The dynamic quantitative weighing system based on the buoyancy weighing sensor is designed in this paper. At first the principle of the dynamic quantitative weighing system is analyzed and then the mathematical model is established. Secondly the hardware structure of the dynamic weighing system is designed. The buoyancy weighing sensor is introduced. The weighing system is composed of two parts: the buoyancy equalizer and the displacement sensor. Through the field tests, precision, stability and sensitivity of the device has been verified.
