1. Karma alloy
Karma alloy inoumbwa nemhangura, nickel, Aluminium neIron sezvinhu zvikuru. Kudzivirira kwayo kwakakwira ka2 ~ 3 kupfuura MENTONG. Ine tembiricha yakaderera yekudzivirira (TCR), thermal EMF yakaderera kana ichienzaniswa nemhangura, inogara kwenguva refu uye inodzivirira oxidation yakasimba. Tembiricha yayo inoshanda.
nzvimbo yacho yakakura kupfuura MENTONG (-60~300ºC). Yakakodzera kugadzira zvinhu zvinodzivirira nekusimba zvakanaka.

2. Saizi yeKarma
Waya: 0.018mm-10mm
Ribhoni: 0.05*0.2mm-2.0*6.0mm
Chidimbu: 0.5*5.0mm-5.0*250mm
Bhawa: 10-100mm

4. 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 kupisa inozove 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.
