摘要
本文介绍在电桥电路中用数调电阻作为可调节的比较元件,在单片机控制下配合传感器,采用示零法实现过程测量的一种方法。
The article present a electronic-bridge measuring method using the zero-reading technique. In this method digital-resistor is used as compare device which match the sensor, and under the control of the singlechip microprocessor, it can realize the procedure measuring.
