Nevertheless, the explosion field is featured with ultrahigh temperature accompanied by shock wave pressure, which imposes severe limitations on the practical performance of most conventional sensors. In this paper, structural optimization, thermoelectric characteristic calibration, dynamic characteristic analysis, and open-field experimental tests are implemented to comprehensively investigate a thermocouple sensor tailored for temperature measurement under explosion environments. Experimental results verify that the developed sensor delivers favorable stability with a measurement uncertainty of 1.96% and outstanding dynamic performance with a response time of 2.74\u00a0ms; meanwhile, it achieves superior reliability under an extreme test condition with a peak temperature of 2697\u2009\u00b0C and a shock wave pressure of 1.342 MPa, demonstrating promising prospects for practical engineering applications.<\/jats:p>","DOI":"10.1063\/5.0336968","type":"journal-article","created":{"date-parts":[[2026,9,9]],"date-time":"2026-09-09T15:21:08Z","timestamp":1788967268000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["Tungsten\u2013rhenium thermocouple for temperature measurement in explosion field"],"prefix":"10.1063","volume":"97","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-2138-0259","authenticated-orcid":false,"given":"Deren","family":"Kong","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering, Nanjing University of Science and Technology , Nanjing,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-3609-9333","authenticated-orcid":false,"given":"Yunhan","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Nanjing University of Science and Technology , Nanjing,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2703-1179","authenticated-orcid":false,"given":"Chundong","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Nanjing University of Science and Technology , Nanjing,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2026,9,9]]},"reference":[{"key":"2026090908472235800_c1","doi-asserted-by":"publisher","first-page":"238","DOI":"10.1016\/j.dt.2025.01.011","article-title":"Experimental study on the TNT equivalence for blast parameters in a confined space","volume":"48","year":"2025","journal-title":"Def.
