感应电势型直线速度检出器

Detecting Velocity on a Linear Moving Object by Induction Electromotive Force

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。本检出器能从带状电阻膜片两电极上检测出与速度成比例的感应电势。

The Induction Electromotive force type velocity detector (IEVD) can directly detect velocity with high resolution, without contact on an object. The IEVD detects electromotive force in proportion to velocity from the pararell electrodes on beltshape resistor film.
