Abstract
An onboard process indicator is provided for measuring the load applied to an axle which is coupled to a vehicle. The onboard weight indicator includes a pivoting beam that is mounted to an axle of the vehicle. The pivoting beam is mounted so that it pivots about a point called the roll-center, which is the center of the suspension. The pivoting beam is also coupled to a transducer and a vertical support. The vertical support and transducer can be located on opposite sides of the roll-center with respect to one another or can be located on the same side of the roll-center. The vertical support and transducer are coupled between the pivoting beam and the frame rail of the vehicle. As a load is applied to the vehicle, the frame rail thereof is moved downwardly. This downward movement is measured by the transducer, which communicates the measured load to a processor. The processor translates the signal from the transducer into process units, and displays this as desired units.
