| Abstract: | The relationship among the range,sensitivity,resolution ratio and precision of an inductive sensor is expounded in this article.According to the relationship,and based on chip AD598AD,a subsequent processing circuit for an inductive sensor is designed.Based on the circuit and a data acquisition card plus a PC program,a high precision and range-adjustable measuring system with inductive displacement sensor is built.The experimental analysis shows that the system is able to reduce the measurement error to be 0.74μm. |
