摘　　要：桥式传感器是汽车衡、轴重秤和仓储秤的一种常用传感器,运用AD芯片HX711自制桥式传感器,研究其测量精度与激励电压的关系,并通过实验找出满足系统测量精度要求情况下的激励电压值。He bridge transducer is used as a normal sensor on motor scale, axle weighing scale and warehouse scale. A homd-made bridge transducer is designed with A/D chip HX711, and the relationship of measurement accuracy and excitation voltage is researched. According to the experiment, the value of excitation voltage is found to satisfy the measurement accuracy.

关 键 词：桥式传感器 HX711 激励电压
