Automated rejection of non-compliant products
Compliance with trade regulations (NTEP, OIML, MID)
Data integration with factory management systems
Dynamic weight compensation for conveyor vibration
Product tracking with timestamped weight records
Automatic tare adjustment for packaging variations
Multi-head configurations for parallel processing (up to 600 items/min)
Vision integration for combined weight+visual inspection
In-line installation between filling and packaging machines
Synchronized rejection with downstream processes
Closed-loop feedback to filling equipment for automatic adjustment
Multi-lane configurations for high-volume production
Startup Verification
Daily check with certified test weights
Zero-point stability confirmation
In-Process Monitoring
