Working Principle

Products enter the weighing conveyor through the feeding conveyor.

The high-speed sensor detects the product position and sends weight information to the control system.

The system compares the measured weight with the preset target range:

✔ Qualified products → Continue to next process
✘ Overweight / Underweight products → Automatically rejected

This ensures consistent product quality and reduces material waste.
