High-Voltage Power Supply for Filling Volume Inspection: High-Speed Online Measurement and Feedback Control

Accurate filling volume control is critical in liquid food and beverage production for product quality and cost efficiency. High-voltage power supplies are used to excite capacitive, conductive, or optical sensors that measure liquid volume, providing precise and stable excitation signals that determine measurement accuracy and response speed.
High-speed online inspection requires microsecond-level response and excellent voltage stability, with amplitude variations limited to 0.01% and minimal ripple. Multi-channel output enables simultaneous monitoring of multiple production lines, increasing throughput.
Closed-loop feedback control ensures precise filling. Sensor data, such as liquid height or volume, is fed back to the power supply controller, which adjusts both filling valves or pumps and the applied voltage to maintain sensor signals within desired ranges. Predictive algorithms can anticipate deviations and pre-adjust voltage output, reducing overfill or underfill events.
Temperature and humidity compensation maintain measurement stability during long production runs. The integration of high-voltage precision and real-time feedback allows continuous, high-speed, and accurate volume control, ensuring consistent product quality and efficient production. This approach provides reliable automation for modern liquid production lines, combining rapid measurement with dynamic process control.
