Kev Piav Qhia Luv:

Kev piav qhia txog khoom
Cov xov hlau tiv thaiv enameled no tau siv dav rau cov qauv resistors, tsheb
cov khoom, cov khoom tiv taus winding, thiab lwm yam siv cov txheej txheem rwb thaiv tsev zoo tshaj plaws rau cov ntawv thov no, siv tag nrho cov yam ntxwv tshwj xeeb ntawm cov txheej enamel.
Tsis tas li ntawd xwb, peb yuav ua cov txheej txheej rwb thaiv tsev ntawm cov hlau muaj nqis xws li hlau nyiaj thiab hlau platinum thaum koj xaj. Thov siv qhov kev tsim khoom no raws li kev txiav txim.
Hom hlau Alloy liab qab
Cov hlau uas peb ua tau enamelled yog tooj liab-nickel hlau hlau, Constantan hlau, Manganin hlau. Kama hlau, NiCr hlau hlau, FeCrAl hlau hlau thiab lwm yam hlau hlau hlau
Kev siv ntawm Constantan
Constantan yog ib qho hlau tooj liab-nickel uas muaj cov khoom me me ntxiv
cov ntsiab lus kom ua tiav cov nqi tseeb rau qhov kub thiab txias coefficient ntawm resistivity. Ceev faj
kev tswj hwm ntawm kev yaj thiab kev hloov pauv ua rau muaj qib qis heev ntawm cov qhov ntawm
cov tuab tuab heev. Cov hlau no siv dav rau cov ntawv ci resistors thiab cov ntsuas kev ntxhov siab.

Kev siv ntawm Constantan
Constantan yog ib qho hlau tooj liab-nickel uas muaj cov khoom me me ntxiv
cov ntsiab lus kom ua tiav cov nqi tseeb rau qhov kub thiab txias coefficient ntawm resistivity. Ceev faj
kev tswj hwm ntawm kev yaj thiab kev hloov pauv ua rau muaj qib qis heev ntawm cov qhov ntawm
cov tuab tuab heev. Cov hlau no siv dav rau cov ntawv ci resistors thiab cov ntsuas kev ntxhov siab.
