QL Quartz Weigh-In-Motion Traffic Sensor Measures Accurately at The Speeds from 5 to 200km/h
The QL WIM sensor fulfills the requirements of the EU, COST 323 A (5), American ASTM 1318-09 Type III and the Chinese GB/T 21296-2007 requirements. It is intended for use in medium speed pre-selection of overweight vehicles and toll plaza weighing. In combination with a charge amplifier and signal-processing system it measures accurately at the speeds from 5 to 200km/h.
The QL WIM sensor offers accurate and precise weight measurements of heavy goods vehicles under rolling traffic condition.
Benefits
●Quartz sensing technology
●High sensitivity, charge output
●Smaller sensor height for easier installation into road pavement
●Measures from low to high speeds
●Wide weight range capable
●Low temperature coefficient
●High measurement accuracy, long-term stability and uniformity
●Robust mechanical structure
Applications
●Weigh-in-motion vehicle weighing
●Bridge protection
●Direct weight enforcement
●Pavement design
●Toll plaza weighing
●Traffic-flow monitoring
●Overweight pre-selection
●Overweight enforcement
●Traffic data collection for pavement design and management
Conformance
Note: The final system performance (weighing accuracy and speed range) is dependent on the pavement conditions, installation quality, the algorithms on the WIM system and other variables.
