Air Suspension Sensor - Onboard Truck Scales | TruckWeight


Air Mechanical

Smart Scale is an accurate, affordable way to save money; time and fuel by eliminate overweight fines, check weighing fees, out of route miles, and increase productivity by reducing time re-working loads. Smart Scale also eliminates complicated installation, maintenance, and downtime associated with hardwired onboard scales and has patented temperature compensation providing for superior accuracy in extreme cold and heat.

Based on temperature and pressure changes in your vehicle’s air suspension, and strain measurements in spring suspensions Smart Scale calculates axle weight and gross vehicle weight measurements that are very accurate. With our dual point calibration process you will never be wondering again how accurate you are when leaving a job site.

Because it’s wireless, Smart Scale lets you monitor gross and axle weights with Quick and Easy Installation, maintenance and a reliable two-year warranty.
