新型传感器部件——可移动铁芯的微型线圈

摘要

介绍一种新型的传感器部件，具有可移动铁芯的微型线圈。这种线圈是通过移动穿过线圈的铁芯，来改变线圈的磁感应强度。它具有灵敏度高、线性度好、体积小、使用方便等特点。适合应用于位移传感器和角度传感器。%A new sensor component- micro coil with a movable core was developed. A movement of the movable core results in a change of inductance．It has a high sensitivity and a good linear. It is tiny and convenient to use. This micro coil can be used on a position sensor or an angular sensor.
