电阻应变式称重传感器是利用电阻应变片组成一单臂电桥，在桥的一对角端加稳定的直流电压，另一对角端随受力的大小，输出相应的电位差。近年来，电子地中衡深受广大用户的欢迎。机械地中衡，也逐渐改造成机电结合式电子地中衡。 在实际检修中，判断是称重显示仪表有故障还是电 Resistance strain gauge load cell is the use of resistance strain gauge composed of a single arm bridge, a pair of corners in the bridge plus a stable DC voltage, the other diagonal end with the size of the force, the output potential difference. In recent years, electronic balance by the majority of users. Mechanical balance, but also gradually transformed into electromechanical integrated electronic balance. In the actual overhaul, the judge is weighing display instrument is faulty or electric
