ABSTRACT:
A system for monitoring the load carried by a vehicle includes a plurality of load cells, each extending between the load bed and the unsprung portion of the vehicle suspension. Each load cell includes an hydraulic cylinder which generates an hydraulic force corresponding to the load applied thereto. A pressure transducer is connected to the hydraulic cylinder, and the outputs of the transducers are summed and fed to an auto zeroing system. The output of this system is connected to an A/D converter, and thence to a visual display. The A/D converter output is also fed to a digital comparator which is connected to a BCD switch set to an overload level. If the load exceeds the BCD input, an overload alarm is sounded.
