光学三角—电涡流复合传感器

The Optical Triangulation—Electromagnetic Whirlpool Compounding Sensor

利用电涡流效应和光学三角测量原理 ,研制出光学三角—电涡流复合传感器 ,主要应用于对涂覆在金属体上的非金属层厚度的测量。并且能够满足工业自动检测中高精度和非接触测量要求 ,同时测量范围和精度可随不同的应用要求而进行大范围的调整。讨论了该传感器在工业领域中的一种实际应用 :测量金属圆柱体表面非金属涂层的偏心。

In this paper we introduce a new kind of sensor. Based on the electromagnetic whirlpool domino effect and optical triangulation principle, the compounding sensor is developed. It is mainly used in the thickness measurement of nonmetal coating mantled on metallic substance. At the same time the sensor can meet the high precision non-contact request in industrial measurement. Also the measurement range can be suitable for different situation. At last the nonmetal coating eccentricity measurement of cylinder as an actual industrial appliance is discussed.
