Ingxubevange yeKarma

I-alloy yeKarma yenziwe ngobhedu, i-nickel, i-Aluminiyam kunye ne-Iron njengezona zinto ziphambili. Ukumelana kwayo kungaphezulu ngokuphindwe ka-2 ~ 3 kune-MENTONG. Ine-coefficient yobushushu obuphantsi (TCR), i-EMF ephantsi yobushushu xa ithelekiswa ne-copper, ukumelana kwayo okuhlala ixesha elide kunye ne-anti-oxidation enamandla. Ubushushu bayo bokusebenza bubanzi kune-MENTONG (-60 ~ 300ºC). Ifanelekile ukwenza izinto ezichaneke ngokuchanekileyo kunye noxinzelelo.

4. Iimpawu ezahlukileyo zentambo yokumelana neKarma

1) Siqala ngentambo yobushushu yombane yeNickel Chromium Class 1, sitshintshe ezinye zeNi nge
u-Al kunye nezinye izinto, ngaloo ndlela waphumelela izixhobo zokuchasana ngokuchanekileyo ngokuphucula
i-coefficient yobushushu bokumelana kunye namandla obushushu e-electromotive ngokuchasene nobhedu.
Ngokongezwa kwe-Al, siphumelele ekwenzeni i-volume resistivity ibe nkulu ngokuphindwe kayi-1.2
kuneNickel Chromium yombane yocingo lobushushu iClass 1 kwaye amandla okutsalwa aphindwe kayi-1.3.

2) I-coefficient yobushushu besibini β yeKarmalloy wire KMW incinci kakhulu, - 0.03 × 10-6/ K2,

kwaye ijika lobushushu bokumelana lijika libe ngumgca othe ngqo ngaphakathi kobubanzi
uluhlu lobushushu.

Ngoko ke, i-coefficient yobushushu imiselwe ukuba ibe yi-coefficient yobushushu obuphakathi
23 ~ 53 °C, kodwa i-1 × 10-6/K, umlinganiselo wobushushu obuphakathi kwe-0 ~ 100 °C, nayo isenokuba
yamkelwe kwi-coefficient yobushushu.

3) Amandla e-electromotive nxamnye nobhedu phakathi kwe-1 ~ 100 °C nawo mancinci, ngaphantsi kwe-+ 2 μV/K, kwaye

ibonisa uzinzo oluhle kakhulu kangangeminyaka emininzi.

4) Ukuba oku kuza kusetyenziswa njengesixhobo sokumelana ngokuchanekileyo, unyango lobushushu obuphantsi luyasetyenziswa
kufuneka kupheliswe ukuphazamiseka kwendlela yokucubungula njengakwimeko ye-Manganin wire CMW.
