Abstract:

An apparatus and method is disclosed for a vehicle on-board weighing system. The system includes sensor housings which may be placed between elements of a load-bearing unit such as the axle and the spring assembly of trucks and tractor-trailers or between the frame and the air-ride housing assembly of vehicles so equipped. A sensor housing is preferably placed at each spring assembly of the vehicle. Each sensor housing contains a weight sensor in the form of a transducer. The electrical output signal of each of the transducers, which is proportional in amplitude to the weight-generated applied, is connected to a monitor module. Total weight of the vehicle load as well as weight distribution of each axle may be indicated by a display on the monitor module. The monitor module contains an eprom that stores information of unsprung weight, installation weight-force, and tare weight of the vehicle. It may also store data from one or more previous readings.
