Shown here is a set of standard weighpads. These pads have been offered by massload for over 10 years. They use a pair of high precision double ended shearbeam loadcells for the weight sensing. The master pad (shown at the bottom) has an M2000 digital indicator built in. There is a large high capacity, rechargeable battery inside the weighpad. The slave weighpad is wired into channel 2 of the M2000, allowing you to view each pad weight individually, as well as the total for the axle.
