In view of conventional sensors' disadvantages such as low signal-to-noise ratio and poor sensitivity to axial cracks, a novel high sensitivity sensor based on orthogonal magnetic field excitation is proposed. Firstly, through a three-dimensional finite element simulation, the remote field effect under orthogonal magnetic field excitation is determined, and an appropriate configuration which can generate an orthogonal magnetic field for a tubular structure is developed. Secondly, optimized selection of key parameters such as frequency, exciting currents and shielding modes is analyzed in detail, and different types of pick-up coils, including a new self-differential mode pick-up coil, are designed and analyzed. Lastly, the proposed sensor is verified experimentally by various types of defects manufactured on a section of a ferromagnetic tube. Experimental results show that the proposed novel sensor can largely improve the sensitivity of defect detection, especially for axial crack whose depth is less than 40% wall thickness, which are very difficult to detect and identify by conventional sensors. Another noteworthy advantage of the proposed sensor is that it has almost equal sensitivity to various types of defects, when a self-differential mode pick-up coil is adopted. ¹Ø¼ü´Ê ×÷Õ߹ؼü´Ê:non-destructive testing; remote field eddy current; sensor; orthogonal magnetic field; finite element simulation KeyWords Plus:COIL; INSPECTION; CRACKS ×÷ÕßÐÅÏ¢ ͨѶ×÷ÕßµØÖ·: Xu, XJ (ͨѶ×÷Õß) Air Force Engn Univ, Sch Informat & Nav, Xian 710077, Peoples R China. µØÖ·: [ 1 ] Air Force Engn Univ, Sch Informat & Nav, Xian 710077, Peoples R China [ 2 ] Air Force Engn Univ, Sch Equipment Management & Safety Engn, Xian 710077, Peoples R China µç×ÓÓʼþµØÖ·:dr_xxj@163.com; lming0601@163.com; zzbin@163.com; jyl1974@126.com »ù½ð×ÊÖúÖÂл »ù½ð×ÊÖú»ú¹¹ ÊÚȨºÅ Chinese National Natural Science Fund 51107148 Natural Science Foundation of Shaanxi Province 2011JQ7006 ²é¿´»ù½ð×ÊÖúÐÅÏ¢¹Ø±Õ»ù½ð×ÊÖúÐÅÏ¢ This work was support by The Chinese National Natural Science Fund (51107148) and The Natural Science Foundation of Shaanxi Province (2011JQ7006). ³ö°æÉÌ MDPI AG, POSTFACH, CH-4005 BASEL, SWITZERLAND Àà±ð / ·ÖÀà Ñо¿·½Ïò:Chemistry; Electrochemistry; Instruments & Instrumentation Web of Science Àà±ð:Chemistry, Analytical; Electrochemistry; Instruments & Instrumentation ÎÄÏ×ÐÅÏ¢ ÎÄÏ×ÀàÐÍ:Article ÓïÖÖ:English Èë²ØºÅ: WOS:000346794300094 PubMed ID: 25615738 ISSN: 1424-8220 ÆÚ¿¯ÐÅÏ¢ Impact Factor (Ó°ÏìÒò×Ó): Journal Citation Reports® ÆäËûÐÅÏ¢ IDS ºÅ: AX2SK Web of Science ºËÐĺϼ¯ÖÐµÄ "ÒýÓõIJο¼ÎÄÏ×": 23 Web of Science ºËÐĺϼ¯ÖÐµÄ "±»ÒýƵ´Î": 0 |
