Mafotokozedwe Akatundu

Waya wa Manganin womwe umagwiritsidwa ntchito kwambiri popanga zida zamagetsi otsika kwambiri zomwe zimafunikira kwambiri, ma resistors ayenera kukhazikika mosamala ndipo kutentha kwa ntchito sikuyenera kupitirira +60 °C. Kupitirira kutentha kwakukulu kogwira ntchito mumlengalenga kungayambitse kusuntha kwa resistance komwe kumachitika chifukwa cha okosijeni. Chifukwa chake, kukhazikika kwa nthawi yayitali kungakhudzidwe molakwika. Zotsatira zake, resistivity komanso kutentha kwa resistance yamagetsi kungasinthe pang'ono. Imagwiritsidwanso ntchito ngati chinthu chosinthira chotsika mtengo chosungunula siliva poyika zitsulo zolimba.

Kugwiritsa Ntchito Manganin:

1; Imagwiritsidwa ntchito popanga kukana kolondola kwa waya

2; Mabokosi otsutsa

3; Zoyezera zamagetsi

Manganin foil ndi waya zimagwiritsidwa ntchito popanga ma resistors, makamaka ma ammeter shunts, chifukwa cha kukana kwake kutentha pafupifupi zero komanso kukhazikika kwa nthawi yayitali. Ma Manganin resistors angapo anali ngati muyezo wovomerezeka wa ohm ku United States kuyambira 1901 mpaka 1990. Manganin wayala imagwiritsidwanso ntchito ngati chowongolera magetsi m'makina a cryogenic, kuchepetsa kusamutsa kutentha pakati pa malo omwe amafunika kulumikizana ndi magetsi.

Manganin imagwiritsidwanso ntchito mu ma gauge pofufuza mafunde amphamvu (monga omwe amapangidwa ndi kuphulika kwa mabomba) chifukwa imakhala ndi mphamvu yochepa koma mphamvu zambiri za hydrostatic pressure.
