High Precision Fully Automatic Weighing Machine with PLC Control for Industrial

Stable Performance Automatic Weighing Machine is an industrial high-precision weighing and checkweighing solution designed for continuous factory production and packaging lines.

The machine combines high-precision load cells, digital weighing control, touchscreen operation, automatic overweight/underweight alarm and production-line connectivity, helping manufacturers improve weighing consistency while reducing manual inspection requirements.

With a configurable weighing range of 10–5000 g and accuracy of approximately ±0.1 g to ±1.0 g depending on product weight and operating speed, the system can be adapted to different industrial weighing requirements.

• Food & Beverage
• Chemical Products
• Industrial Components
• Packaging Lines
• Logistics & E-Commerce

Industrial-grade load cells and digital signal processing provide stable measurement during continuous operation.

High accuracy / stable weighing / consistent measurement / automatic inspection

The weighing accuracy can reach: ±0.1 g to ±1.0 g

Actual accuracy depends on product weight, operating speed and production conditions.

The machine can be integrated into continuous conveyor-based production and packaging lines.

Maximum conveyor speed: Up to 60 m/min
