1. Karma alloy

Karma alloy inoumbwa nemhangura, nickel, Aluminium neIron sezvinhu zvikuru. Kudzivirira kwayo kwakakwirira ka2 ~ 3 kupfuura MENTONG. Ine tembiricha yakaderera yekudzivirira (TCR), thermal EMF yakaderera kana ichienzaniswa nemhangura, inogara kwenguva refu uye inodzivirira oxidation yakasimba. Tembiricha yayo yekushanda yakafara kupfuura MENTONG (-60 ~ 300ºC). Yakakodzera kugadzira zvinhu zvinodzivirira zvine hungwaru uye kusvuta.

2. Saizi yeKarma

Waya: 0.01mm-10mm
Ribhoni: 0.05*0.2mm-2.0*6.0mm
Chidimbu: 0.5*5.0mm-5.0*250mm
3. Zvinhu zvakasiyana zvewaya yekudzivirira Karma

1) Kutanga neNickel Chromium electric heat wire Class 1, takatsiva mamwe maNi ne
Al nezvimwe zvinhu, uye nokudaro vakawana zvinhu zvinodzivirira zvakarurama nekuvandudzwa
chiyero chekupisa chinodzivisa uye simba remagetsi rinorwisa mhangura.
Nekuwedzera kweAl, takabudirira mukuwedzera simba rekudzivirira vhoriyamu neka1.2
kupfuura Nickel Chromium electric heat wire Class 1 uye simba rekudhonza rakapetwa ka1.3.

2) Chiyero chechipiri chekupisa β cheKarmalloy wire KMW chidiki kwazvo, - 0.03 × 10-6/ K2,

uye curve yekudzivirira tembiricha inozobuda yakaita mutsetse wakatwasuka mukati mehupamhi
tembiricha yemhando yepamusoro.

Saka, chiyero chekupisa chakagadzirirwa kuva chiyero chekupisa pakati pe
23 ~ 53 °C, asi 1 × 10-6/K, avhareji yekupisa pakati pe0 ~ 100 °C, inogonawo
shandiswa pakuenzanisa tembiricha.

3) Simba remagetsi rinorwisa mhangura riri pakati pe1 ~ 100 °C dikiwo, riri pasi pe + 2 μV/K, uye

inoratidza kugadzikana kwakanaka kwenguva yakareba.

4) Kana ichi chichifanira kushandiswa sechinhu chinodzivisa kururama, kurapwa kwekupisa kushoma kunoitwa
zvinodiwa kubvisa kukanganisa kwekugadzirisa sezvazvakaita paManganin wire CMW.
