| High Light | Class III Accuracy Weigh in Motion Controller ，16 Detection Channels WIM Data Logger ，4G LTE Wireless Communication Low Speed Weighing Controller | ||
The data logger for low-speed weigh-in-motion (WIM) systems is primarily used for dynamic weighing applications on highways, direct overloading enforcement, toll stations, and source weighing in logistics parks. As the core data processing unit, it collects sensor and vehicle identification signals, performs axle load and total weight calculations, and manages data output and local storage.
This controller serves as the central processing unit for low-speed WIM systems, acquiring signals from front-end devices including weighing sensors, charge amplifiers, and vehicle separators. Equipped with proprietary dynamic weighing algorithms, it calculates axle load, group-axle weight, axle configuration, vehicle speed, and gross vehicle weight in real-time while vehicles pass at low speeds.

The weighing controller features a front touch panel with real-time status indicators. Input and output interfaces are located on the left and right sides of the equipment.
Outputs two sets of switch signals synchronized with vehicle entry and exit. Both sets are normally open when no vehicle is triggered; output signal closes when vehicle enters weighing area and opens when vehicle leaves. Solid-state relay dry contacts with drive capability of 30VDC, 0.5A.
