WEIGHING SYSTEMS
CATEGORIES OF WEIGHING SYSTEMS• Portable wheel or axle weighers• On-board weighing system• Single axle weighbridge• Full length plate weighbridge• Part length weighbridge
PROJECT PLANS - OPTION 2• Full Plate Weighbridge Installation
• Weight indicator Embedded with Software
• Open architecture connectivity with peripherals (Options: Traffic lights, barrier gate operators, RFID or barcode card reader, photocells).
• Integration with the Existing Control System
• At maximum weight , Conveyor would change position to another truck
• Automatic number plate recognition systems
