The weighing system includes at least one position indicator for each axle to be monitored which provides electrical signals which vary in accordance with the built position of the frame relative to the axle which is being monitored. The weighing system also includes a programmed central processing unit for receiving the electrical signals from the position indicator and for calculating the load weight on the frame, based on the value of the electrical signals. | |
