4. Mamiriro akasiyana eKarma resistance wire
1) Kutanga neNickel Chromium yemagetsi kupisa waya Kirasi 1, takatsiva imwe yeNi neAl uye zvimwe zvinhu, uye nekudaro takawana chaiyo yekudzivirira zvinhu neyakagadziridzwa yekudzivirira tembiricha coefficient uye kupisa electromotive simba kurwisa mhangura.
Nekuwedzera kweAl, isu takabudirira kugadzira 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 yekudzivirira inoshanduka kuita inenge mutsara wakatwasuka mukati mehupamhi hwetembiricha.
Naizvozvo, tembiricha coefficient inoiswa kuti ive 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 force against copper iri pakati pe1 ~ 100 °C idikiwo, pazasi + 2 μV/K, uye inoratidza kugadzikana kwakanakisa kwenguva yemakore akawanda.
4) Kana izvi zvichizoshandiswa sechinhu chakasimba chekudzivirira, kupisa kwekushisa kwepasi kunodiwa kubvisa kukanganisa kugadzirisa sezvakangoita Manganin waya CMW.
