4. Izici ezihlukile ze-Karma resistance wire
1) Ukuqala nge-Nickel Chromium yentambo yokushisa kagesi kagesi Yekilasi 1, sashintsha enye ye-Ni safaka i-Al nezinye izakhi, futhi ngaleyo ndlela sazuza okunembayo kokumelana nesilinganiso sokushisa esithuthukisiwe sokumelana namandla okushisa e-electromotive ngokumelene nethusi.
Ngokungezwa kwe-Al, siphumelele ukwenza ivolumu yokuphikiswa izikhathi eziphindwe ka-1.2
kunentambo yokushisa kagesi ye-Nickel Chromium Ikilasi 1 namandla aqinile ngokuphindwe izikhathi ezingu-1.3.
2) I-coefficient yesibili yokushisa engu-β ye-Karmalloy wire KMW incane kakhulu, - 0.03 × 10-6/ K2,
futhi ijika lokushisa lokumelana liphenduka cishe umugqa oqondile ngaphakathi kwebanga lokushisa elibanzi.
Ngakho-ke, i-coefficient yezinga lokushisa isethwe ukuthi ibe isilinganiso sesilinganiso sokushisa esiphakathi kuka-23 ~ 53 °C, kodwa 1 × 10-6/K, isilinganiso se-coefficient yezinga lokushisa phakathi kuka-0 ~ 100 °C, nayo ingase
yamukelwe i-coefficient yezinga lokushisa.
3) Amandla kagesi ngokumelene nethusi phakathi kuka-1 ~ 100 °C nawo mancane, ngaphansi kuka-+2 μV/K, futhi abonisa ukuzinza okuhle kakhulu phakathi nenkathi yeminyaka eminingi.
4) Uma lokhu kuzosetshenziswa njengento yokumelana nokunemba, ukwelashwa kokushisa okuphansi kuyadingeka ukuze kuqedwe ukuhlanekezelwa kokucubungula njengoba kwenzeka ku-Manganin wire CMW.
