一种快速精密位移测量电路的设计

The Design of A Circuit for Rapid and Accurate Measuring of Displacement

本文分析了双螺管线田基动型电感传感器交流电桥的电气特性，介绍了一种位移测量电路，该电路对传感器测量电排进行高精度恒交流激励，跟踪采样被测交流信号峰值，保证了测量的快速精密。

In this paper the electric properties of an alternate current bridge of an inductive coiled-coil sensor are analyzed. then a circuit used for measuring of displacement is introduced, which drives the bridge of the inductive coiled-coil sensor with constant alternate current. tracks and samplcs the peak value of the signal to be measured.so as to ensure the rapidity and accuracy of the measurement.
