Kistler introduced its Weigh In Motion system (WIM) that facilitates direct enforcement of roadway weight limitations in accordance with legal requirements.
This innovative Weigh In Motion system uses sensors with multiple quartz crystals that independently deliver data via a digital interface to detect overweight vehicles. The digital measuring signal permits individual calibration of each quartz crystal and prevents signal interference on the transmission path.
Working from the measurement signals, sophisticated algorithms calculate the wheel, axle and total weight of each vehicle. The open standard interfaces allow this system to be easily integrated into third-party traffic monitoring systems.
The sensor results are accurate even when the vehicle being measured is about to overtake and is driving diagonally over the Weigh In Motion sensor arrangement.
At the same time, monitoring can be carried out on any number of lanes. The sensors also provide information on whether a vehicle is equipped with single or dual tires and can draw conclusions about the condition of the tires.
The system is OIML-R-134 certified and compliant with COST 323 & ASTM E1218-09
