Mafotokozedwe Akatundu

Waya wa Manganin womwe umagwiritsidwa ntchito kwambiri popanga zida zotsika kwambiri zokhala ndi zofunikira kwambiri, zopinga ziyenera kukhazikika bwino ndipo kutentha kwa ntchito sikuyenera kupitilira +60 ° C.Kupitilira kutentha kwakukulu kogwira ntchito mumpweya kungayambitse kusuntha kosunthika kopangidwa ndi oxidizing.Choncho, kukhazikika kwa nthawi yaitali kungakhudzidwe molakwika.Chotsatira chake, resistivity komanso kutentha kwa kutentha kwa magetsi kungasinthe pang'ono.Amagwiritsidwanso ntchito ngati zotsika mtengo m'malo zinthu zogulitsira siliva pakupanga zitsulo zolimba.

Mapulogalamu a Manganin:

1;Amagwiritsidwa ntchito popanga mabala osalimba kwambiri

2;Mabokosi otsutsa

3;Zotchingira zida zoyezera zamagetsi

Manganin zojambulazo ndi waya amagwiritsidwa ntchito popanga resistors, makamaka ammeter shunts, chifukwa cha pafupifupi ziro coefficient kutentha kwa mtengo kukana ndi kukhazikika kwa nthawi yaitali.Manganin resistors angapo adakhala ngati muyezo walamulo wa ohm ku United States kuyambira 1901 mpaka 1990. Manganin wire amagwiritsidwanso ntchito ngati kondakitala wamagetsi mu machitidwe a cryogenic, kuchepetsa kutentha kwapakati pakati pa mfundo zomwe zimafuna kulumikizidwa kwa magetsi.

Manganin amagwiritsidwanso ntchito poyesa mafunde amphamvu kwambiri (monga omwe amapangidwa kuchokera kuphulika kwa zophulika) chifukwa ali ndi mphamvu yocheperako koma imakhudzidwa kwambiri ndi hydrostatic pressure sensitivity.
