On-Board Weighing for Air-Ride Suspensions

PRECISIONAIR

Accurate and reliable payload measurement is an important element of profitability in the bulk hauling business. Whether you haul feeds, fertilizers, woodchips, solid and liquid waste, or liquid and dry bulk commodities, PRECISIONLOADS

air suspension kits are the preferred choice to provide consistent truck, trailer and total weights. PRECISIONAIR

on-board scales are engineered to fit your truck and trailer air-ride suspensions without expensive mounting labor. Fitting a full or half system can be completed in a just couple of hours, and by simply following our 3-step manual.

Some important PRECISIONAIR

features are:

Unique split-system sensor arrangement and special Immediate Response height control valve provide exceptional scale performance in both normal and off-road loading conditions.
Single, Dual and Quad channel display models suit a wider range of scale applications.
Read Total and Truck & Trailer gross or payload weights simultaneously, while you load and without pushing buttons.
Easy Trailer ID function provides multiple trailer interchangeability.
Air + Load Cell system combinations fit every possible tractor/trailer configuration, including fixed and sliding 5th wheel kits, trailer kingpin kits, and single point and equalizing leaf spring suspensions.
