Recently, the planar inductor is commonly used to detect wear debris. The previous studies have found that the inductive signal would be varied while changing the position of wear debris pass through. However, the effect of position on the wear debris detection is not well understood. In this paper, a novel detection system in which the position of wear debris pass through could be adjusted precisely is designed. By changing the position in horizontal or vertical direction, the inductive signals of the wear debris were acquired. In the horizontal direction, the experimental results show that the amplitude of the inductive signal first increases and then decreases when the position changes from the center of the planar inductor to the outer. The maximum inductive signal appears when the wear debris pass through the edge of the inner coil, which is 20% higher than that for the center and much higher than that for the edge of outer coil. In the vertical direction, the signal decreases almost linearly when the position is away from the planar inductor. For every 0.1 mm step far away the planar inductor, the signal amplitude drops by approximately 10%. The variation trend of our experimental results is consistent with the numerical simulation results of magnetic intensity around the planar inductor.<\/jats:p>","DOI":"10.3390\/s19224961","type":"journal-article","created":{"date-parts":[[2019,11,14]],"date-time":"2019-11-14T10:56:34Z","timestamp":1573728994000},"page":"4961","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["The Effects of Position on the Wear Debris Detection with Planar Inductor"],"prefix":"10.3390","volume":"19","author":[{"given":"Yi","family":"Yin","sequence":"first","affiliation":[{"name":"College of Marine Engineering, Dalian Maritime University, Dalian 116026, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhijian","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Marine Engineering, Dalian Maritime University, Dalian 116026, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Zheng","sequence":"additional","affiliation":[{"name":"College of Marine Engineering, Dalian Maritime University, Dalian 116026, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liang","family":"Chen","sequence":"additional","affiliation":[{"name":"College of Marine Engineering, Dalian Maritime University, Dalian 116026, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sen","family":"Wu","sequence":"additional","affiliation":[{"name":"College of Marine Engineering, Dalian Maritime University, Dalian 116026, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Saijie","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Science, Dalian Maritime University, Dalian 116026, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhijun","family":"Yan","sequence":"additional","affiliation":[{"name":"College of Marine Engineering, Dalian Maritime University, Dalian 116026, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0251-5679","authenticated-orcid":false,"given":"Xinxiang","family":"Pan","sequence":"additional","affiliation":[{"name":"College of Marine Engineering, Dalian Maritime University, Dalian 116026, China"},{"name":"College of Navigation, Guangdong Ocean University, Zhanjiang 524088, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,11,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"473","DOI":"10.1016\/j.triboint.2017.01.015","article-title":"Lubricating oil conditioning sensors for online machine health monitoring\u2014A review","volume":"109","author":"Zhu","year":"2017","journal-title":"Tribol.
