However, it is difficult to achieve real-time monitoring of the temperature field of tube furnaces with existing technology. Here, we proposed a method to fabricate silver (Ag) resistance temperature detectors (RTDs) based on a blade-coating process directly on the surface of a quartz ring, which enables precise positioning and real-time temperature monitoring of tube furnaces within 100\u2013600 \u00b0C range. The Ag RTDs exhibited outstanding electrical properties, featuring a temperature coefficient of resistance (TCR) of 2854 ppm\/\u00b0C, an accuracy of 1.8% FS (full scale), and a resistance drift rate of 0.05%\/h over 6 h at 600 \u00b0C. These features ensured accurate and stable temperature measurement at high temperatures. For demonstration purposes, an array comprising four Ag RTDs was installed in a tube furnace. The measured average temperature gradient in the central region of the tube furnace was 5.7 \u00b0C\/mm. Furthermore, successful real-time monitoring of temperature during the alloy sintering process revealed approximately a 20-fold difference in resistivity for silver-palladium alloys sintered at various positions within the tubular furnace. The proposed strategy offers a promising approach for real-time temperature monitoring of tube furnaces.<\/jats:p>","DOI":"10.3390\/s24102999","type":"journal-article","created":{"date-parts":[[2024,5,9]],"date-time":"2024-05-09T05:16:45Z","timestamp":1715231805000},"page":"2999","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Printed Thick Film Resistance Temperature Detector for Real-Time Tube Furnace Temperature Monitoring"],"prefix":"10.3390","volume":"24","author":[{"given":"Zhenyin","family":"Hai","sequence":"first","affiliation":[{"name":"Department of Mechanical and Electrical Engineering, School of Aerospace Engineering, Xiamen University, Xiamen 361005, China"}]},{"given":"Zhixuan","family":"Su","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Electrical Engineering, School of Aerospace Engineering, Xiamen University, Xiamen 361005, China"}]},{"given":"Kaibo","family":"Zhu","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Electrical Engineering, School of Aerospace Engineering, Xiamen University, Xiamen 361005, China"}]},{"given":"Yue","family":"Pan","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Electrical Engineering, School of Aerospace Engineering, Xiamen University, Xiamen 361005, China"}]},{"given":"Suying","family":"Luo","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Electrical Engineering, School of Aerospace Engineering, Xiamen University, Xiamen 361005, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"45","DOI":"10.1016\/j.ijpvp.2016.05.001","article-title":"Effect of steamside oxidation and fireside corrosion degradation processes on creep life of service exposed boiler tubes","volume":"144","author":"Kumar","year":"2016","journal-title":"Int.
