4. Mamiriro akasiyana eKarma resistance wire
1) Kutanga neNickel Chromium yemagetsi kupisa waya Kirasi 1, takatsiva imwe yeNi ne
Al nezvimwe zvinhu, uye nekudaro vakawana chaiyo yekupikisa zvinhu nekuvandudzwa
kuramba tembiricha coefficient uye kupisa electromotive simba kurwisa mhangura.
Nekuwedzera kweAl, takabudirira mukugadzira vhoriyamu resistivity 1.2 times hombe
kupfuura Nickel Chromium yemagetsi kupisa waya Kirasi 1 uye simba rekusimba rakapetwa ka1.3.
2) Yechipiri tembiricha coefficient β yeKarmalloy waya KMW idiki kwazvo, - 0.03 × 10-6/ K2, uye tembiricha yekupikisa inoshanduka kuita inenge mutsara wakatwasuka mukati mehupamhi.
tembiricha range.
Naizvozvo, iyo tembiricha coefficient inotarwa kuve avhareji tembiricha coefficient pakati
23 ~ 53 °C, asi 1 × 10-6/K, avhareji tembiricha coefficient pakati 0 ~ 100 °C, zvakare anogona
kugamuchirwa kune tembiricha coefficient.
3) Electromotive simba kurwisa mhangura pakati pe1 ~ 100 °C idiki zvakare, pazasi + 2 μV/K, uye
inoratidza kugadzikana kwakanakisa kwenhambo yemakore akawanda.
4) Kana izvi zvichizoshandiswa seyakanyatso kupikisa zvinhu, yakaderera tembiricha kupisa kurapwa ndiko
inodiwa kubvisa kukanganisa kugadzirisa sezvakangoita Manganin waya CMW.
