High-Speed Weigh-in-Motion (WIM) Telemetry
Piezoelectric quartz crystal sensors embedded in highway travel lanes sampling at 10kHz to measure gross vehicle mass and individual axle load distributions within 3% accuracy.
Vehicle Suspension Dynamic Bounce Decoupling
Multi-sensor Kalman estimators filter vehicle chassis pitch, bounce, and axle hop frequencies, extracting the true static equivalent axle weight from oscillatory sensor data.
- Weighing accuracy within ±3% at speeds up to 130 km/h.
- Instantaneous detection of illegal axle overweight violations.
- Automated diversion of overweight assets before structural bridge access.
- 100% compliance with ASTM E1318-09 Type III weigh-in-motion standards.
