supplying an independent filling control. The board is intelligent and
powerful enough for OEM customers – it is ready to accept piggy-back
modules and/or embedded applications for OEM special requirements.
1.2 Typical Applications
• Dynamic weighing – vehicles, livestock
• Dynamic force measurement
• High speed checkweighing
• High speed filling / batching
• Beltweighing
• Force measurement / Press Machines
• WIM-Monitor for analysis of dynamic systems
