Hlau manganinSiv dav rau cov cuab yeej siv hluav taws xob tsawg nrog qhov xav tau siab tshaj plaws, cov resistors yuav tsum tau ua tib zoo ruaj khov thiab qhov kub ntawm daim ntawv thov yuav tsum tsis pub tshaj +60 ° C. Tshaj qhov kub ua haujlwm siab tshaj plaws hauv huab cua yuav ua rau muaj kev tsis kam los ntawm oxidizing. Yog li, qhov ruaj khov mus sij hawm ntev tuaj yeem cuam tshuam tsis zoo. Yog li ntawd, qhov resistivity nrog rau qhov kub thiab txias ntawm qhov tsis kam hluav taws xob yuav hloov me ntsis. Nws kuj tseem siv ua cov khoom hloov pauv pheej yig rau cov nyiaj solder rau cov hlau tawv mounting.

Cov Ntawv Thov Manganin:

1; Nws yog siv rau kev ua hlau qhov txhab precision tsis kam

2; Cov thawv tiv thaiv

3; Shunts raucov cuab yeej ntsuas hluav taws xob

Cov ntawv ci thiab hlau manganin siv rau hauv kev tsim cov resistors, tshwj xeeb tshaj yog ammeterkev hloov pauv, vim nws qhov kub thiab txias coefficient ntawm tus nqi tsis kam thiab kev ruaj khov ntev. Ntau lub Manganin resistors tau ua haujlwm raws li tus qauv kev cai lij choj rau ohm hauv Tebchaws Meskas txij li xyoo 1901 txog 1990. Manganin hlau kuj tseem siv ua tus neeg coj hluav taws xob hauv cov kab ke cryogenic, txo qis kev hloov pauv cua sov ntawm cov ntsiab lus uas xav tau kev sib txuas hluav taws xob.

Manganin kuj tseem siv rau hauv cov ntsuas rau kev kawm txog cov nthwv dej siab (xws li cov uas tsim los ntawm kev tawg ntawm cov khoom tawg) vim nws muaj qhov rhiab heev qis tab sis muaj qhov rhiab heev hydrostatic siab.
