I-KarmaIntambo Yokumelana Yezinto Zokumelana Nezifudumezi

I-Chemical Element: Cr 19~21.5%, Ni: Ibhalansi, Al 2.5~3.2%, Fe 2.5~20%

Ukumelana: 1.33 ohm mm2/m

Ukumelana okungu-800 Ohms Nge-Mil Foot Ejikelezayo ku-20° C (68° F)
Isisindo nge-intshi ye-cubic =. 293 lbs.

Amandla adonsela phansi athile 8.10

Ububanzi 0.025mm ~ 5mm

Ukusetshenziswa: i-resistor

Izici ezihlukile zocingo lokumelana neKarma

1) Siqala nge-Nickel Chromium kagesi we-heat wire Class 1, sishintshe ezinye ze-Ni nge
I-Al nezinye izakhi, ngaleyo ndlela yathola ukumelana okunembile ngezinto ezithuthukisiwe
i-coefficient yokumelana nokushisa kanye namandla okushisa e-electromotive ngokumelene nethusi.
Ngokungezwa kwe-Al, siphumelele ekwenzeni ukumelana kwevolumu kube kukhulu ngokuphindwe ka-1.2
kune-Nickel Chromium kagesi i-heat wire Class 1 kanye namandla okunamathela amakhulu ngokuphindwe ka-1.3.

2) I-coefficient yesibili yokushisa β ye-Karmalloy wire KMW incane kakhulu, - 0.03 × 10-6/ K2,
futhi ijika lokushisa lokumelana liphenduka cishe libe umugqa oqondile ngaphakathi kobubanzi
ububanzi bokushisa.

Ngakho-ke, i-coefficient yokushisa isethwe ukuthi ibe yi-coefficient yokushisa ephakathi
23 ~ 53 °C, kodwa 1 × 10-6/K, isilinganiso sokushisa esiphakathi kuka-0 ~ 100 °C, singase futhi
kufanele yamukelwe ngokwesilinganiso sokushisa.

3) Amandla e-electromotive ngokumelene nethusi eliphakathi kuka-1 ~ 100 °C nawo mancane, ngaphansi kuka-+ 2 μV/K, futhi
ikhombisa ukuzinza okuhle kakhulu esikhathini seminyaka eminingi.

4) Uma lokhu kuzosetshenziswa njengento yokumelana nokunemba, ukwelashwa kokushisa okuphansi kuyasebenza
kudingeka ukuze kuqedwe ukuphazamiseka kokucubungula njengoba kunjalo nge-Manganin wire CMW.

Siphinde sikhiqize olunye uhlobo lwentambo yokumelana njenge-NiCr 80/20, i-NiCr 70/30, i-Nicr 60/15, i-Cr25Al5, njll.
