HOW IT WORKS

Air Suspension System

Our scales monitor axle groups with air suspension that are automatically regulated by one or more height control valves. Our scales are not compatible with air assisted spring suspension or independent lift axles with manual air pressure regulators.

Height Control Valve

The height control valve automatically regulates the pressure in the air suspension to constantly maintain a pre-set ride height between the frame and the axles.

When weight is applied or removed from the vehicle, the ride height changes and triggers the height control valve to increase or decrease the air pressure in the suspension in order to return the vehicle to optimal ride height.

Our scales associate the air pressure in the suspension system to the weight you enter at the time of calibration. Once calibrated, our scales accurately display the on-the-ground weight of the axle group by showing any change in pressure as a change in weight.

A typical axle group consists of one, two or three axles that are automatically regulated together by one or two height control valves.

Single Axle

Our scales monitor single axle groups that are monitored by one or two height control valves, left to right. The axle group can be a steer axle group, the drive axle group or a trailer axle group.

Tandem Axle

Our scales monitor tandem axle groups that are monitored by one or two height control valves, left to right. The axle group can be a steer axle group, the drive axle group or a trailer axle group.

Tri Axle

Our scales monitor tri axle groups that are monitored by one or two height control valves, left to right. The axle group can be the drive axle group or a trailer axle group.

RIGHT WEIGH LOAD SCALES

Using a basic T-fitting and an extra air line, our scales monitor the fluctuation in air pressure of the air suspension system to display on-the-ground weight.

The picture to the left illustrates our scale installed on an air suspension system with an axle group that is controlled by one height control valve. For axle groups that are regulated by two height control valves from left to right, two air lines are needed to install the scale.
