A precision Displacement measurement system is designed based on the principle of electromagnetic induction. The system consists of the Wienbridge oscillating circuit、difference amplifier、Solenoid drive circuits and induced circuit、data acquisition and processing、 display and control circuits. The system transforms the magnetic core displacement into the alteration of the secondary voltage of the induced circuit, and rectified circult with the precision active rectification function. Finally Data acquisition and processing are achieved by Singlechip Computer, and the direction and size of the displacement are obtained. The system also can be used to control the Motor running, to achieve the precision displacement control according to the requirement. Test results demonstrate that, the accuracy of the Displacement measurement and control could reach down to 0.1 mm.
