An MFL coil sensor is designed and tested with pipe sample thicknesses of 2, 4, 6, and 8 mm based on the magnetic field effect of ferrite cores. Moreover, a measurement setup for analysing pipe samples up to a temperature of 200\u00b0 Celsius is suggested. Experimental results reveal that the MFL coil sensor can fulfil the requirements for MFL testing of pipes in high temperature conditions, and that the precision of MFL monitoring of pipes to detect corrosion at high temperatures can be improved significantly.<\/jats:p>","DOI":"10.3390\/s21093033","type":"journal-article","created":{"date-parts":[[2021,4,27]],"date-time":"2021-04-27T06:19:11Z","timestamp":1619504351000},"page":"3033","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Development of an MFL Coil Sensor for Testing Pipes in Extreme Temperature Conditions"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2295-7693","authenticated-orcid":false,"given":"Nagu","family":"Sathappan","sequence":"first","affiliation":[{"name":"School of Engineering, London South Bank University, London SE1 0AA, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammad Osman","family":"Tokhi","sequence":"additional","affiliation":[{"name":"School of Engineering, London South Bank University, London SE1 0AA, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liam","family":"Penaluna","sequence":"additional","affiliation":[{"name":"NDT Section (NSIRC), TWI, Cambridge CB21 6AL, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhangfang","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Engineering, London South Bank University, London SE1 0AA, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fang","family":"Duan","sequence":"additional","affiliation":[{"name":"School of Engineering, London South Bank University, London SE1 0AA, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6832-6849","authenticated-orcid":false,"given":"Gholamhossein","family":"Shirkoohi","sequence":"additional","affiliation":[{"name":"School of Engineering, London South Bank University, London SE1 0AA, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8946-567X","authenticated-orcid":false,"given":"Aman","family":"Kaur","sequence":"additional","affiliation":[{"name":"London South Bank Innovation Center, Cambridge CB21 6AL, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2474","DOI":"10.1016\/j.rser.2009.03.014","article-title":"Economic analysis of power generation from parabolic trough solar thermal plants for the Mediterranean region\u2014A case study for the island of Cyprus","volume":"13","author":"Poullikkas","year":"2009","journal-title":"Renew.
