Freightliner Trucks is offering the Air-Weigh in-dash on-board truck and trailer scale system as a factory option for all truck models with air suspensions. The Air-Weigh Self-Weighing Truck Scale can improve productivity and reduce operating costs and delays caused by check-weighing at truckstop scales.

The Air-Weigh system consists of an in-cab truck scale and a remote trailer scale. The in-cab unit acts as the system master controller. It displays steer, drive, and lift axle weights, up to seven trailer suspension weights if equipped, GVW, and net payload weight.

This scale is calibrated to each vehicle's suspension and weight, which is measured by an installed air pressure sensor in the suspension air line. Once the system is calibrated, the Air-Weigh scale displays the weight of the axle group to within 300 pounds of a DOT-certified scale.

When a self-weighing tractor picks up a trailer equipped with the Air-Weigh trailer scale, the trailer weight data is automatically transmitted to the truck scale in-cab display gauge and is included in the GVW and net payload weights.

The Air-Weigh gauges are available in chrome or black bezel and fit into standard 2" in-dash gauge holes.

Air-Weigh's AW5800 series scale system is available on any Freightliner Trucks medium- or heavy-duty truck models with rear or combination front and rear air suspensions. Direct sensing of the front axle is also provided on vehicles with the Freightliner AirLiner front suspension. On tractors without front air suspension, the Air-Weigh truck scale automatically calculates the transfer of weight on and off the steer axle.
