1. Evanohm alloy
Daawaha Evanohm waxa uu ka kooban yahay naxaas, nikkel, Aluminium iyo Iron sida qaybaha ugu muhiimsan. Iska caabintu waa 2 ~ 3 jeer ka sarreeya MENONG. Waxay leedahay heerkulka hoose ee iska caabinta (TCR), kulaylka hoose ee EMF iyo naxaas, joogtaynta wanaagsan ee caabbinta muddo dheer iyo anti-oxidation xooggan. Heerkulkeeda shaqadu way ka ballaaran tahay MENTONG (-60 ~ 300ºC). Waxay ku habboon tahay samaynta walxaha iska caabinta saxda ah iyo cadaadiska.
2. Xajmiga Evanohm
Xadhkaha: 0.018mm-10mm
Ribbon: 0.05*0.2mm-2.0*6.0mm
Xarig: 0.5*5.0mm-5.0*250mm
Bar: 10-100mm

4. Astaamaha gaarka ah ee siligga iska caabinta Evanohm
1) Laga bilaabo Nickel Chromium siligga kuleylka korantada fasalka 1, waxaan ku beddelnay qaar ka mid ah Ni
Al iyo walxo kale, oo sidaas awgeed lagu gaadhay walxo iska caabin sax ah oo la wanaajiyey
Heerkulka isku-xidhka iska caabinta iyo kulaylka xoogga kuleyl ee ka dhanka ah naxaasta.
Marka lagu daro Al, waxaan ku guuleysanay inaan sameyno iska caabin mugga 1.2 jeer ka weyn
marka loo eego nickel Chromium siligga kulaylka korontada ee fasalka 1 iyo xoogga xajinta 1.3 jeer ka weyn.
2) Isku-xidhka heerkulka sare ee β ee siliga Karmalloy KMW waa mid aad u yar, - 0.03 × 10-6 / K2,
iyo qalooca heerkulka iska caabintu waxay noqotaa mid ku dhow xariiq toosan oo ballaaran dhexdeeda
kala duwanaanta heerkulka.
Sidaa darteed, isku xidhka heerkulku waxa loo dejiyay inuu noqdo celceliska isku xidhka heerkulka u dhexeeya
23 ~ 53 °C, laakiin 1 × 10-6/K, isku celceliska heerkulka u dhexeeya 0 ~ 100 °C, sidoo kale waxaa laga yaabaa.
loo qaato isku-xidhka heerkulka.
3) Xooga koronto ee ka soo horjeeda naxaasta inta u dhaxaysa 1 ~ 100 °C sidoo kale waa yar yahay, oo ka hooseeya + 2 μV/K, iyo
waxay muujisaa xasillooni aad u wanaagsan muddo sanado badan ah.
4) Haddii tan loo isticmaalo sida walxaha iska caabbinta saxda ah, daaweynta kulaylka hooseeya waa
loo baahan yahay si loo baabi'iyo qalloocyada habaysan sida kiiska Manganin silig CMW.
