How does my scale work?
LoadMaxx works on tractors with air drive suspensions and most trucks with leaf spring steer axles and air suspension drive axles. Air sensors measure pressure in the air bags, and deflection sensors measure flex for axles with leaf spring suspensions. The scale converts the sensor measurements into accurate on-the-ground weights.
When properly calibrated and used, LoadMaxx is accurate to within 300 lbs on each axle group.
