Ingxubevange yeKarma

I-alloy ye-Karma yenziwe ngethusi, i-nickel, i-Aluminium kanye ne-Iron njengezingxenye eziyinhloko. Ukumelana kwayo kuphakeme ngokuphindwe kabili kuya kathathu kune-MENTONG. Ine-coefficient yokumelana nokushisa okuphansi (i-TCR), i-EMF ephansi yokushisa uma iqhathaniswa nethusi, ukumelana okuhlala isikhathi eside kanye ne-anti-oxidation enamandla. Ububanzi bayo bokushisa obusebenzayo bubanzi kune-MENTONG (-60~300ºC). Ifaneleka ukwenza izinto zokumelana nokunemba okuhle kanye nobunzima.

4. 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.
