Abstract

Weighing technology is closely connected with people's life. A wide-range low-cost high precision portable piezoelectric weighing sensor system were designed for the wide weighing scale range applications based on improved resistance strain gauges Wheatstone bridge. Sensing unit, processing circuit, digital display and portable panel were studied. The modified full-bridge strain-bridge circuit which has the 8 times weighing range than typical products in the market were designed. The whole size of scale body is 0.5m*0.35m*0.02m. The error of weight from 0kg to 8000kg was no more than 15 kg. The displayed number of display device and the weight of corresponding object showed a good linear relation. It was realizable to weight wide-range objects such as poultry with lower cost and portability.
