I-6J12, eyaziwa nangokuthi i-modified Manganin, iyi-alloy yokumelana nethusi-manganese-nickel enembile kakhulu.
Ihlelwe ngokwezinga likazwelonke laseShayina i-GB/T 15018-1994, eyenzelwe izinhlelo zokusebenza ezidinga amazinga okumelana azinzile kakhulu kanye nokushintshashintsha okuncane kwezinga lokushisa.
Okuvelele Okubalulekile:
l Isilinganiso sokushisa sokumelana okuphansi kakhulu (i-TCR)
l I-EMF ephansi yokushisa ngokumelene nethusi
l Ukuqina okuhle kakhulu kwesikhathi eside
l Ukuguquguquka okuhle kokudweba intambo encane
l Kufanelekela izinhlelo zokulinganisa nokulawula ezisebenza ngokunemba okuphezulu
Ukusungulwa: Ukuzalwa kweManganin (1892)
Umsuka we6J12ibuyela emuva ekusungulweni kweManganin ngusosayensi waseBrithani u-Edward Weston ngo-1892.
l 1887: UWeston wadala iConstantan, i-alloy yokuqala yokumelana ne-TCR ephansi.
l 1892: I-Manganin yathuthukiswa ngefomula ye-Cu86%, Mn12%, Ni2%.
l Ukuphumelela okuyinhloko: I-TCR eseduze ne-zero eduze nokushisa kwegumbi, okuqinisekisa ukumelana okuzinzile.
l 1901–1990: Ama-resistors e-manganin asebenze njengendinganiso esemthethweni ye-ohm e-United States.
Lokhu kusungulwa kwabeka isisekelo sazo zonke izinto zokumelana nokunemba zesimanje.
Ukuziphendukela Kwemvelo: Kusukela ku-Manganin kuya ku-6J12
I-6J12 inguqulo yaseShayina ethuthukisiwe futhi esezingeni elifanele yeManganin yendabuko, elungiselelwe izidingo zesimanje zezimboni.
Ngawo-1950: IShayina yaqala ukucwaninga nokuthuthukisa okuzimele kanye nokwenziwa kwendawo kwama-alloy anembile ukuze iqede ukuncika ekungenisweni kwempahla kwamanye amazwe.
l 1994: IShayina yakhipha i-GB/T 15018-1994, yaqamba ngokusemthethweni i-alloy elungiselelwe kahle i-6J12.
l Ukuthuthukiswa: Kungezwe i-trace Si ne-Fe ukuze kuthuthukiswe ukumelana nokushisa nokusebenza kokucubungula.
l Inzuzo: Ukuqina okungcono ezindaweni ezishisa kakhulu, ezinomswakama ophezulu kanye nezindawo zezimboni ezinzima.
