However, the temperature drift of the exciting coil has a considerable influence on the precision of PEC testing. The objective of this study is to investigate the temperature drift effect and reduce its impact. The temperature drift effect is analyzed theoretically and experimentally. The temperature drift effect on the peak-to-peak values of the output signal is investigated, and a temperature compensation method is proposed to reduce the effect of temperature variation. The results show that temperature drift has a negative impact on PEC testing and the temperature compensation method can effectively reduce the effect of temperature drift.<\/jats:p>","DOI":"10.3390\/s18061952","type":"journal-article","created":{"date-parts":[[2018,6,15]],"date-time":"2018-06-15T11:21:20Z","timestamp":1529061680000},"page":"1952","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["A Temperature Drift Compensation Method for Pulsed Eddy Current Technology"],"prefix":"10.3390","volume":"18","author":[{"given":"Biting","family":"Lei","sequence":"first","affiliation":[{"name":"School of Mechanical Science & Engineering, Huazhong University of Science & Technology, Wuhan 430074, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pengxing","family":"Yi","sequence":"additional","affiliation":[{"name":"School of Mechanical Science & Engineering, Huazhong University of Science & Technology, Wuhan 430074, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yahui","family":"Li","sequence":"additional","affiliation":[{"name":"School of Mechanical Science & Engineering, Huazhong University of Science & Technology, Wuhan 430074, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiayun","family":"Xiang","sequence":"additional","affiliation":[{"name":"School of Mechanical Science & Engineering, Huazhong University of Science & Technology, Wuhan 430074, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,6,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"26","DOI":"10.1016\/j.sna.2009.11.012","article-title":"Defect classification based on rectangular pulsed eddy current sensor in different directions","volume":"157","author":"He","year":"2010","journal-title":"Sens.
