This study introduces a novel combined thickness measurement method employing fuzzy logic, with the aim of broadening the applicational scope of the EMAT. Leveraging minimal hardware, this method utilizes the short pulse time-of-flight (TOF) technique for initial thickness estimation, followed by secondary measurements guided by fuzzy logic principles. The integration of measurements from the resonance, short pulse echo, and linear frequency modulation echo extends the measurement range while enhancing accuracy. Rigorous experimental validation validates the method\u2019s effectiveness, demonstrating a measurement range of 0.3\u20131000.0 mm with a median error within \u00b10.5 mm. Outperforming traditional methods like short pulse echoes, this approach holds significant industrial potential.<\/jats:p>","DOI":"10.3390\/s24134066","type":"journal-article","created":{"date-parts":[[2024,6,24]],"date-time":"2024-06-24T06:59:58Z","timestamp":1719212398000},"page":"4066","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Thickness Measurements with EMAT Based on Fuzzy Logic"],"prefix":"10.3390","volume":"24","author":[{"given":"Yingjie","family":"Shi","sequence":"first","affiliation":[{"name":"Collaborative Innovation Center of Steel Technology, University of Science and Technology Beijing, Beijing 100083, China"},{"name":"Institute of Acoustics, Chinese Academy of Sciences, Beijing 100190, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1631-1968","authenticated-orcid":false,"given":"Shihui","family":"Tian","sequence":"additional","affiliation":[{"name":"Collaborative Innovation Center of Steel Technology, University of Science and Technology Beijing, Beijing 100083, China"}]},{"given":"Jiahong","family":"Jiang","sequence":"additional","affiliation":[{"name":"Collaborative Innovation Center of Steel Technology, University of Science and Technology Beijing, Beijing 100083, China"}]},{"given":"Tairan","family":"Lei","sequence":"additional","affiliation":[{"name":"Collaborative Innovation Center of Steel Technology, University of Science and Technology Beijing, Beijing 100083, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9458-6089","authenticated-orcid":false,"given":"Shun","family":"Wang","sequence":"additional","affiliation":[{"name":"Collaborative Innovation Center of Steel Technology, University of Science and Technology Beijing, Beijing 100083, China"}]},{"given":"Xiaobo","family":"Lin","sequence":"additional","affiliation":[{"name":"Institute of Acoustics, Chinese Academy of Sciences, Beijing 100190, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1809-7413","authenticated-orcid":false,"given":"Ke","family":"Xu","sequence":"additional","affiliation":[{"name":"Collaborative Innovation Center of Steel Technology, University of Science and Technology Beijing, Beijing 100083, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,6,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"34","DOI":"10.1016\/j.ndteint.2018.10.001","article-title":"A Study of Magnetostriction Mechanism of EMAT on Low-Carbon Steel at High Temperature","volume":"101","author":"Ren","year":"2019","journal-title":"NDT E Int."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"8064","DOI":"10.1109\/JSEN.2018.2863546","article-title":"Optimal Design of Point-Focusing Shear Vertical Wave Electromagnetic Ultrasonic Transducers Based on Orthogonal Test Method","volume":"18","author":"Jia","year":"2018","journal-title":"IEEE Sens.
