4. Iimpawu ezahlukileyo zeKarma resistance wire
1) Ukuqala nge-Nickel Chromium ngocingo olushushu lombane lweClass 1, sitshintshe enye ye-Ni nge
I-Al kunye nezinye izinto, kwaye ngaloo ndlela ifezekiswe ngokuchaneka kwezinto zokumelana nokuphuculwa
ukumelana nobushushu obulinganayo kunye nobushushu be-electromotive force ngokuchasene nobhedu.
Ngokudityaniswa kwe-Al, siye saphumelela ukwenza 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 yobushushu besibini β yeKarmalloy wire KMW incinci kakhulu, - 0.03 × 10-6/ K2, kwaye ijiko lokumelana nobushushu lijika liphantse libe ngumgca othe tye ngaphakathi kobubanzi.
uluhlu lobushushu.
Ngoko ke, i-coefficient yokushisa imiselwe ukuba ibe yi-coefficient yeqondo lokushisa eliphakathi
23 ~ 53 °C, kodwa 1 × 10-6/K, i-avareji yomlinganiso wobushushu phakathi kwe-0 ~ 100 °C, nayo
yamkelwe i-coefficient yobushushu.
3) Amandla ombane ngokuchasene nobhedu phakathi kwe-1 ~ 100 °C nawo amancinci, ngaphantsi + 2 μV/K, kunye
ibonisa uzinzo olubalaseleyo kwithuba leminyaka emininzi.
4) Ukuba oku kuya kusetyenziswa njengento yokumelana ngokuchanekileyo, unyango lobushushu obuphantsi lulo
Kuyafuneka ukuphelisa ukugqwethwa kokwenziwa komsebenzi njengoko kunjalo kwimeko yocingo lweManganin CMW.
