Gadzira Nickel Karma/EvanohmPrecision Alloy WireyeDefrost muchina

1. Evanohm alloy

Evanohm alloy inogadzirwa nemhangura, nickel, Aluminium uye Iron sezvinhu zvikuru. Iyo resistivity ndeye 2 ~ 3 nguva yakakwirira kupfuura MENTONG. Iyo ine yakadzika tembiricha coefficient yekupikisa (TCR), yakadzika yekupisa EMF inopesana nemhangura, yakanaka yekugara kwekupokana kwenguva yakareba uye yakasimba anti-oxidation. Kushanda kwayo tembiricha yakafara kupfuura MENTONG (-60 ~ 300ºC). Inokodzera kugadzira yakanakisa precision resistance elements uye strain.

2. Evanohm saizi

waya: 0.018mm-10mm
Ribhoni: 0.05 * 0.2mm-2.0 * 6.0mm
Mutsara: 0.5 * 5.0mm-5.0 * 250mm
Bhawa: 10-100mm

3.Evanohm Property

4. Mamiriro akasiyana eEvanohm 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, 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
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.
