ABSTRACT:
A weight-measuring and display device includes a rigid structural housing for supporting a load positioned thereon and a strain-sensing and weight-displaying circuit located within the structural housing. The rigid structural housing includes a top plate on which the user stands or the load is placed, a bottom plate and three deflection beams horizontally arranged between the top and bottom plates. Mounted to the top of each deflection beam is a strain gauge and mounted to the bottom of each deflection beam is another strain gauge. The group of three top mounted strain gauges accounts for the resistance in one arm of a wheatstone bridge and the group of three bottom mounted strain gauges accounts for the resistance in a second, adjacent arm of the wheatstone bridge. In addition to the wheatstone bridge, the strain-sensing and weight-displaying circuit further includes an amplifier portion, an analog to digital converter, a BCD to seven-segment decoder and three, seven-segment LED readouts.
