Power is transferred to each device by direct contact rather than via a magnetic field and induction.

这样就能直接给设备供电，无需借助磁场和感应电流。

The Induction Electromotive force type velocity detector (IEVD) can directly detect velocity with high resolution, without contact on an object.

感应电势型速度检出器(IEVD)以较高的精度直接检测，对测定对象无接触，故对测定对象的移动不产生影响。
