Weigh In Motion System Overview
The Weigh In Motion Sensors provide cutting-edge vehicle weight measurement technology for traffic management, toll collection, and vehicle classification. Utilizing quartz piezoelectric effect technology, these sensors deliver high sensitivity and precision across a wide speed range with accuracy of ±1% to ±3% of actual weight.
Key Performance Features
Factory calibration with on-site adjustment capability ensures precise tuning before delivery and fine-tuning during installation. Operating effectively from -30 to +70°C, these sensors maintain consistent performance in harsh environmental conditions. With output impedance of 100Ω and linearity of ≤ ±2 FOS%, they provide reliable, repeatable measurements for both low-speed and high-speed weigh in motion applications.
