Vehicle Separation Loop Detector is the core vehicle separation device for dynamic weighing and overload off-site law enforcement system. Cooperated with pre-buried road induction loops, it continuously monitors inductance variation of loops to detect passing vehicles. It outputs vehicle separation signals to weighing instruments and capture controllers, effectively separating closely following vehicles and avoiding mixed weighing data. It works reliably under rain, snow, fog and dust conditions.
