摘要

新型工业无损检测(NDT)需要开发新型探头，因为电感线圈传感器的使用仅限于低频应用，例如检测深埋裂纹和试样边缘的缺陷。本文讨论了磁传感器(巨磁电阻和磁通门传感器)。本文介绍了所选传感器的比较、性能及其在无损检测中的应用。

Detection sensors for electromagnetic nondestructive evaluation

New industrial Non Destructive Testing (NDT) requires the development of new probes because the use of inductance coil sensors are limited for low frequency application such as for detection of deep buried cracks and defect on the edge of the specimen. This paper deals with magnetic sensors (giant magnetoresistance - GMR and fluxgate sensors). The comparison of selected sensors, their properties and application in nondestructive testing are presented in this article.
