摘要
无损测厚是工程技术中一个重要课题。介绍一个 LC振荡电路的测厚装置 ,其测量原理及装置都非常简单 ,而测量结果能与专门的超声波测厚仪相媲美。对铁磁材料本身缺陷的探测也有很好的应用 ,而且造价低、体积小、现场应用方便。
A simple and speedy device for measuring the thickness of the coatings of ferromagnetic materials with oscillating circuit was presented, which was small in size, cheap in price and easy to operate. The measuring resolution was of 5μm with the measuring range of 300μm.
