摘　　要：由电阻应变式构成的传感器或是组成的测力装置系统中,在利用反馈补偿手段进行测量惠斯顿电桥输出方法时,用于补偿桥路输出的应变电压的补偿电压取之于被测桥路,桥路信号经与补偿信号作矢量叠加便产生桥补结合的效果。电桥信号经过这样处理后,可使被测桥路不会产生非线性现象、桥压变化不影响测量精度等一些优点。In the resistance strain sensors or force testing system,when the feedback compensation method is used to test the output of the Wheatstone bridge,the compensation voltage to compensate the output strain voltage of the bridge circuit is from the testing bridge circuit.The superimposed vector between the bridge circuit signal and the compensation signal results in the bridge compensation combination effect.After the bridge signal is managed,nonlinear phenomenon will be avoided in the testing circuit and the measurement accuracy is not affected by the bridge voltage variation.
