Abstract:
A weight sensing pad includes two spaced apart load cells, each including a fixed end bending beam deflectable by vertical loads applied to the pad by the wheel of a vehicle and electrical strain gages for sensing beam deflection. The pad includes electronic control circuitry connecting the strain gages in a wheatstone bridge circuit, and providing calibration, zero, output, and bridge sensitivity adjustments. Two or more pads can be serially interconnected electrically with a remote electronic weight indicator.
