Spring Suspension

Spring Suspension System

The Right Weigh spring ride load sensor for our Exterior Digital Scale is designed to measure the on-the-ground weight of spring suspension trailers.

Axle Load Sensor

The precision sensor attached to the center of the axle detects the strain in the axle. This strain is then measured and converted to pounds or kilograms by the Right Weigh digital scale system.

HOW IT WORKS

The trailer weight puts strain on the axle because the load is coming straight down on the springs and an equally opposite force is coming up through the tires. This strain on the axle is then measured by the precision sensors and converted to pounds or kilograms by the Right Weigh digital scale system using the calibration information entered by the user during initial setup.

Guidelines for Configuration

  • The Spring Ride sensor can only be used to gauge the weight for trailers
  • Compatible with most axle diameters and shapes
  • Each axle in the axle group must have one sensor installed
  • Only one digital scale is necessary to read all the sensors per axle group

INSTALLATION

The Right Weigh spring suspension sensor must be installed while the axle group is empty and attached to the top center of the axle. There must be at least 9 inches (230 mm) of open space between the brake booster brackets.

WEIGHING CONDITIONS

The accuracy of the scale is dependent on the mechanical repeatability of your leaf-spring suspension as well as the ground surface conditions. Follow these weighing guidelines to optimize the accuracy of the scale readings within 1-4%.
