Proper tip clearance can reduce the gas leakage over turbine blade tips and improve the engine efficiency of turbo machinery and reduce the fuel consumption. Therefore, accurate tip clearance measurement is essential. The inductive measurement method is one of the non-contact distance measurement methods, which has the characteristics of high sensitivity, fast response speed, and strong anti-interference ability. Based on the principle of inductive sensor measuring tip clearance, the ambient temperature change may cause the material electromagnetic performance change for the conductivity and permeability varies with temperature. In order to verify the temperature effect on the sensor performance, the repeated calibration experiments were carried out to obtain the sensor repeatability error of 5.4%. Then, the sensor was calibrated in the range of 0 mm\u20134 mm clearance at temperature from 600 \u00b0C to 1000 \u00b0C and obtained the measurement error of 4.6%. Results indicate when the temperature ranged from 600 \u00b0C to 1000 \u00b0C, clearance measurement error is smaller than the sensor repeatability error so the temperature effect on the sensor characteristics can be ignored. This conclusion makes the sensor promising for monitoring the blade tip clearances at various temperature environment.<\/jats:p>","DOI":"10.3390\/s19173694","type":"journal-article","created":{"date-parts":[[2019,8,26]],"date-time":"2019-08-26T04:38:23Z","timestamp":1566794303000},"page":"3694","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Experimental Investigation of Inductive Sensor Characteristic for Blade Tip Clearance Measurement at High Temperature"],"prefix":"10.3390","volume":"19","author":[{"given":"Zhenxia","family":"Liu","sequence":"first","affiliation":[{"name":"School of Power and Energy, Northwestern Polytechnical University, Youyi West Road 127#, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5239-3323","authenticated-orcid":false,"given":"Ziyu","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Power and Energy, Northwestern Polytechnical University, Youyi West Road 127#, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yaguo","family":"Lyu","sequence":"additional","affiliation":[{"name":"School of Power and Energy, Northwestern Polytechnical University, Youyi West Road 127#, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lingqiang","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Power and Energy, Northwestern Polytechnical University, Youyi West Road 127#, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,8,25]]},"reference":[{"key":"ref_1","unstructured":"Scott, B.L., and Bruce, M.S.
