一种电感式大位移传感器的理论与设计

The Design of an Inductance Type of Position Sensor

提出了一种高精度超长位移传感器的理论及设计方法，并在此基础上研制了新颖的电感式位移传感器．传感器由线圈（又称动尺）、按一定几何形状设计的固定铁芯（又称定尺）和导磁罩组成，当线圈在铁芯上移动时。

An inductance type of position sensor is presented and its operating theory and design method are also described. The position sensor consists of a Coil, an immovable iron column or core, and a magnetic covering. This sensor is characterized of smart structure and cheap costing, large sensing length (larger than 1000mm), high accuracy (less than 1mm) and fine linearity. It can measure position in many cases and can be working steadily in harsh situations for a long time.
