Explain the dynamic weighing principle of the dosing weighing system

2025-05-10

The dynamic weighing principle of dosing&weighing system Technological process: Calibration: Establish a linear relationship between mass flow rate and sensor signal using standard materials of known mass, such as glass microspheres. Real time monitoring: During the material conveying process, sensors continuously collect signals and combine them with speed sensors (such as screw speed) to calculate instantaneous flow rate. Closed loop control: PLC dynamically adjusts the feeder speed or valve opening based on the deviation between the set value and the actual flow rate. Key parameters: Flow range: 0.1 kg/h~100 t/h (depending on feeder type and sensor range). Control accuracy: ± 0.5%~± 2% (lower than static weighing in dynamic environments). Repeatability: The RSD (relative standard deviation) of 10 consecutive measurement results is less than 1%. case: Coating of positive electrode material for lithium batteries: The dynamic weighing system controls the slurry flow rate (accuracy ± 1%) to ensure that the density fluctuation of the electrode surface is less than ± 1.5%. ...
