Dynamic Weighing
WIM Sensor
Product application
1, Free way, high way speeding monitoring governance
2, Highway weight charges
3, Road traffic statistic, vehicle classification
4, Road carrying capacity scientific research
5, Road, bridge security operation management
6, Digital highway construction
CWST QST8400 Piezoelectric WIM Sensor
The piezoelectric quartz WIM sensors adopt piezoelectric quartz crystal as a measuring sensor and use patented
structure. The sensor has four standard length: 1 m, 1.5 m and 1.75 m, 2 m. Thus it can accommodate different
widths of lanes, and adapt to dynamic road weighing needs.
