The DAW 300 Bluetooth® is a portable Weigh-In-Motion System with wireless technology. The weighing system can be installed on any level area within minutes. The rated weighing capacity is up to 20 tonnes (44,000 lbs) per axle and can weigh vehicles at speeds up to 10 kph (6 mph). Measured loads are sent wirelessly via Bluetooth® wireless technology to a laptop to be displayed on the screen. Limits for single axles, axle groups and total weight are programmable. Overweights are displayed when pre-programmed weight limits are exceeded. Weighpads are powered by a Lithium-Ion battery pack that provides 12 to 15 hours of continuous operation. Full recharging time is 3.5 hours and a smart charger is included with each weighpad.
The dynamic weighing plates consist of a high-strength thin steel plate. Wire strain gauges are used for measuring the load. The entire weighpad is covered with hot vulcanized neoprene rubber. The weighing plate has handles on either end and the handle opposite to the Bluetooth® antenna is equipped with rollers for easy movement. For temporary installations the weigh plates can be placed on level ground with approach and departure ramps. For best accuracy the weigh plates can be installed in shallow pits so that their surfaces are flush with the roadway.
