摘要
本文通过对脉冲感应型磁场传感器的感应电压进行精确的理论推导，得到检测量与传感器结构、激励磁场、被测磁场之间的定性关系，讨论两种测量方案：单线圈双向励磁和双线圈单向励磁，它们的误差来源、影响和消除措施，从而得出各自的适用范围。
This paper presents the theoretical calculation of the inductive voltage of pulse induction magnetic sensors. The quantitative relationship between the sensor output and structure, exciting magnetic field, and magnetic field under test is found. It also discusses the error sources and their eliminating methods of such two pick up schemes as single pick up coil excited alternatively from both ends, and double pick up coil excited only one way, and points out their respective ranges of applications.
