Air-Weigh 5800 Series Tractor Scales from Air-Weigh Onboard Scales

Company Profile
Air-Weigh Tractor Scales are an option for most vehicle models with air suspensions. The in-dash LCD gauge is mounted in a standard 2-inch hole and provides digital weights to within 300 lbs (140 kgs) of a DOT scale. When an Air-Weigh equipped tractor is connected to an Air-Weigh equipped trailer, the trailer axle weight is automatically transmitted to the truck scale and displayed on the in-dash gauge display.

The 5800 Series on-board scale converts tractor and trailer suspension loads to an accurate on-the-ground weight. By comparing empty and loaded axle group weights with empty and loaded suspension pressures, the scale can be calibrated to display accurate weights at any suspension load. The kit provides the standard in-dash Air-Weigh features and displays steer and drive weights, and also trailer weights with either an optional air line to the trailer suspension or a 5802 Series Trailer Scale. Gross Vehicle Weight and Net Payload are also displayed, by toggling the display.

All of the electronics are installed in the cab. The kit includes Air-Weigh's in-dash gauge, a ComLink Electronic Control Unit (ECU), and one weight sensor.

For accurate weights within 300 pounds, Air-Weigh recommends that the user:

* Calibrate the scale system with the tractor and trailer brakes released to release suspension binding. Calibrating or observing weight readings with the brakes engaged will result in inaccuracy.
* Perform calibration and weighing on a level surface with the vehicle adequately chocked to prevent rolling.
* When equipped with air-suspension dump valves, momentarily exhaust the suspension (5-10 seconds of air dump is normally sufficient) and re-inflated before calibrating or weighing. This will improve repeatability and accuracy.

In addition to the features noted above, the standard kit also includes alarms and warnings for all axle weights, GVW, and Net Payload, plus J1708 integration capability, a printer option, optional all-Spanish displays and more. The alarm feature of the Air-Weigh scale helps drivers to determine when the vehicle weight is approaching desirable limits, while either loading or off-loading.
