摘　　要：介绍了地磁感应线圈的工作原理,针对投弃式探头水下转速测量需要,设计专用线圈传感器及测量电路,并搭建专用试验台进行室内试验。试验结果表明,采用地磁感应线圈可以准确地得到旋转体转速信息,可应用于投弃式探头水下转速测量。The theory of operation of geomagnetic induction coil is introduced in this paper. For meeting the requirements of measuring the rotation of expendable probes, a special coil and measuring circuit are designed, and a special test-bed is set up for experiments in lab for measuring the rotation of expendable probes. Results of experiments show that exact data about the velocity of the probe rotation can be obtained with the geomagnetic induction coil, and it is indicated that the device can be employed for determining the underwater rotation of expendable probes.
