Mu nganda zikora ubushyuhe bwinshi, gupima ubushyuhe neza kandi bwizewe ni inkingi ikomeye yo kugenzura ubuziranenge bw'ibicuruzwa, umutekano w'imikorere, no gukoresha neza ingufu.Imiyoboro yo kurinda thermocouple ya silikoni iboshywe na nitride (NB SiC)Igaragara nk'igisubizo cyiza cyane, ikoresheje ibyiza bya silicon nitride na silicon carbide kugira ngo irusheho kuba nziza mu bihe bikomeye. Uretse imikorere yayo idasanzwe, ubushobozi bwacu bwo guhindura ibintu butuma ihuzwa neza n'inganda zitandukanye, bigatuma iba amahitamo meza ku nganda mpuzamahanga.
Imiyoboro yo kurinda thermocouple ya NB SiC ikoreshwa mu nganda nyinshi zikenerwa cyane, bitewe n’imiterere yayo idasanzwe—ubushyuhe bwinshi bugera kuri 1500°C, ubushyuhe bwiza burwanya impanuka, no kurwanya ingese. Mu gutunganya ibyuma bidakoresha feri, ni ngombwa cyane mu gupima ubushyuhe mu itanura rya aluminium, zinc, umuringa, na manyeziyumu. Bitandukanye n’ibikoresho gakondo, NB SiC ntihumanya ibyuma bishongeshejwe, igenzura ko ibicuruzwa bya nyuma ari byiza mu gihe ikomeza kugumana ubuziranenge igihe kirekire. Ku nganda zikora ibyuma n’ibyuma, iyi miyoboro ikora neza mu itanura riturika no mu buryo bwo gushyuha, yihanganira kwangirika kw’umukungugu mwinshi na scoria.
Urwego rwa peteroli n'ibinyabutabire rwungukira cyane ku kudakora neza kwabyo mu binyabutabire, birwanya isuri bitewe na aside ikomeye, alkali, n'imyuka y'uburozi mu byuma bikoresha amakara n'imiyoboro y'ibinyabutabire. Bikora neza cyane mu nganda zikoresha imyanda n'ibikoresho bitwika, bigakomeza ahantu hashyushye cyane harimo sulfure na chloride. Byongeye kandi, mu nganda zitunganya ubushyuhe, ikirahure, n'inganda zitunganya ubushyuhe, ingano yabyo y'ubushyuhe buke (4.7 × 10⁻⁶/°C kuri 1200°C) ituma habaho gukora neza mu gihe cy'ubushyuhe bwihuse n'ubukonje, bigatuma ubushyuhe bukwirakwira neza.
Imiyoboro yacu yo kurinda thermocouple ya NB SiC itanga uburyo bwo guhindura ibintu mu buryo bwuzuye kugira ngo ihuze n'ibikenewe byihariye by'umushinga. Ku bijyanye n'ingano, dutanga uburebure bwo hanze bworoshye (8mm kugeza 50mm) n'ubugari bw'imbere (8mm kugeza 26mm), hamwe n'uburebure bushobora guhindurwa kugeza kuri 1500mm cyangwa burebure hashingiwe ku bishushanyo. Guhindura imiterere y'inyubako birimo gushushanya igice kimwe kugira ngo bikomere neza kandi habeho uburyo butandukanye bwo gushyiraho—nk'imigozi ya M12×1.5 cyangwa M20×1.5, imigozi idahinduka cyangwa yimukanwa, n'imiterere ifite imigozi—kugira ngo ihuze neza n'ibikoresho bihari.
Imiterere y'ibikoresho ishobora kandi guhindurwa, aho ingano ya SiC iri hagati ya 60% na 80% naho ingano ya Si₃N₄ ikaba hagati ya 20% na 40%, bihuza imikorere n'ikiguzi ku bijyanye n'ingese cyangwa ubushyuhe runaka. Dutanga kandi uburyo bwo kuvura ubuso kugira ngo tugabanye ubwiyongere bw'imyenge (kugeza kuri <1% ubwiyongere bw'imyenge y'ubuso) no kunoza ubwiyongere bw'imyenge, ndetse no gupakira ibintu byihariye kugira ngo bikoreshwe mu ngendo ndende. Dushyigikiwe no kugenzura ubuziranenge no gutanga vuba (kohereza mu masaha 48 y'ubutabazi bwihutirwa birahari), twemeza ko imikorere ihoraho kandi igatangwa ku gihe.
Hitamo imiyoboro ya thermocouple ya silikoni iboshywe na nitride kugira ngo ipime ubushyuhe mu buryo bwizewe mu bidukikije bikomeye. Ubuhanga bwacu mu guhindura ibintu butuma bikwiranye neza n'ibyo ukenera mu nganda zawe, bikagabanya ikiguzi cyo kubungabunga no gukora akazi. Twandikire uyu munsi kugira ngo tuganire ku bipimo byawe kandi ubone igisubizo gikwiye.
