The probe is combined with two orthogonal driver traces and a pickup coil that includes two-circular sector windings with series connection. Rotational eddy currents are induced by driver traces of the same amplitude and frequency, but fed with 90\u00b0 phase different alternating exciting currents. An experimental demonstration using prototypes of the probes and artificial defects showed that the probe with a two-circular sector pickup coil is more sensitive for detecting the short defects than the probe with a circular pickup coil.<\/jats:p>","DOI":"10.3390\/s19214628","type":"journal-article","created":{"date-parts":[[2019,10,25]],"date-time":"2019-10-25T04:41:27Z","timestamp":1571978487000},"page":"4628","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["A Novel Rotational Field Eddy Current Planar Probe with Two-Circular Sector Pickup Coils"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6070-3881","authenticated-orcid":false,"given":"Guolong","family":"Chen","sequence":"first","affiliation":[{"name":"School of mechanical and electrical engineering, Lanzhou university of technology, Lanzhou 730050, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weimin","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of mechanical Engineering, Beijing institute of technology, Beijing 100081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wuyin","family":"Jin","sequence":"additional","affiliation":[{"name":"School of mechanical and electrical engineering, Lanzhou university of technology, Lanzhou 730050, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weihan","family":"Pang","sequence":"additional","affiliation":[{"name":"Beijing Key Laboratory of Civil Aircraft Structures and Composite Materials, Beijing Aeronautical Science &amp; Technology Research Institute of COMAC, Future Science and Technology Park, Changping, Beijing 102211, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zheng","family":"Cao","sequence":"additional","affiliation":[{"name":"School of mechanical and electrical engineering, Lanzhou university of technology, Lanzhou 730050, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kang","family":"Wang","sequence":"additional","affiliation":[{"name":"School of mechanical and electrical engineering, Lanzhou university of technology, Lanzhou 730050, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhibo","family":"Song","sequence":"additional","affiliation":[{"name":"School of mechanical and electrical engineering, Lanzhou university of technology, Lanzhou 730050, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,10,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"342","DOI":"10.4283\/JMAG.2013.18.3.342","article-title":"Review paper: Application of the Pulsed Eddy Current Technique to Inspect Pipelines of Nuclear Plants","volume":"18","author":"Park","year":"2013","journal-title":"J.
