4. Iimpawu ezahlukileyo zeKarma resistance wire
I-1) Ukuqala nge-Nickel Chromium yocingo lobushushu lombane loMbane weKlasi yoku-1, satshintsha enye ye-Ni kunye ne-Al kunye nezinye izinto, kwaye ngaloo ndlela siphumelele izinto ezichanekileyo zokumelana nomgangatho wobushushu obuphuculweyo kunye nobushushu be-electromotive force ngokuchasene nobhedu.
Ngokudityaniswa kwe-Al, siye saphumelela ekwenzeni i-resistivity ye-volume 1.2 amaxesha amakhulu
kuneNickel Chromium ucingo lobushushu lombane Udidi loku-1 kunye namandla okuqina aphindwe ka-1.3.
2) I-coefficient yesibini yobushushu be-β ye-Karmalloy wire KMW incinci kakhulu, - 0.03 × 10-6/ K2,
kwaye ijiko lobushushu lokumelana lijika libe phantse umgca othe tye ngaphakathi koluhlu olubanzi lobushushu.
Ke ngoko, umlinganiso weqondo lobushushu umiselwe ukuba ube ngumlinganiso wobushushu ophakathi kwe-23 ~ 53 °C, kodwa i-1 × 10-6/K, i-coefficient yobushushu obuphakathi phakathi kwe-0 ~ 100 °C,
yamkelwe i-coefficient yobushushu.
3) Amandla ombane ngokuchasene nobhedu phakathi kwe-1 ~ 100 °C nawo amancinci, ngezantsi + 2 μV/K, kwaye abonisa uzinzo olubalaseleyo kwithuba leminyaka emininzi.
4) Ukuba oku kuya kusetyenziswa njengento yokumelana ngokuchanekileyo, unyango lobushushu obuphantsi luyafuneka ukuze kupheliswe ukuphazamiseka kokucubungula njengoko kunjalo kwimeko yeManganin wire CMW.
