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 yekupikisa zvinhu neyakagadziridzwa yekudzivirira 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 yekudzivirira inoshanduka kuita inenge mutsara wakatwasuka mukati mehupamhi hwetembiricha renji.
Naizvozvo, 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) Simba remagetsi kurwisa mhangura iri pakati pe1 ~ 100 °C idiki zvakare, pazasi + 2 μV/K, uye inoratidza kugadzikana kwakanakisa kwenhambo yemakore akawanda.
4) Kana ichi chichizoshandiswa sechinhu chakasimba chekudzivisa, kupisa kwakadzika kwekushisa kunodiwa kubvisa kukanganisa kugadzirisa sezvakangoita Manganin waya CMW.
