Karma Enamelled Wire Dia 0.08mm Resistance Cua Sov Hlau rau Precision Instrument

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.

4. Cov yam ntxwv sib txawv ntawm Karma tsis kam hlau

1) Pib nrog Nickel Chromium hluav taws xob cua sov hlau Class 1, peb tau hloov qee qhov Ni nrog
Al thiab lwm yam ntsiab lus, thiab yog li ntawd tau txais cov khoom siv tiv taus precision nrog kev txhim kho
tsis kam kub coefficient thiab cua sov electromotive force tawm tsam tooj liab.
Nrog rau kev ntxiv ntawm Al, peb tau ua tiav hauv kev ua kom lub ntim resistivity 1.2 npaug ntau dua
dua li Nickel Chromium hluav taws xob cua sov Class 1 thiab lub zog tensile 1.3 npaug ntau dua.

2) Tus coefficient kub theem ob β ntawm Karmalloy hlau KMW yog me heev, - 0.03 × 10-6/ K2,

thiab qhov nkhaus kub tiv taus hloov pauv mus ua yuav luag ib txoj kab ncaj nraim hauv qhov dav
qhov kub thiab txias.

Yog li ntawd, qhov coefficient ntawm qhov kub thiab txias yog teem rau qhov nruab nrab ntawm qhov kub thiab txias ntawm
23 ~ 53 °C, tab sis 1 × 10-6 / K, qhov nruab nrab kub coefficient ntawm 0 ~ 100 ° C, kuj tseem yuav
yuav tsum tau siv rau qhov coefficient ntawm qhov kub thiab txias.

3) Lub zog hluav taws xob tawm tsam tooj liab ntawm 1 ~ 100 ° C kuj me me, qis dua + 2 μV / K, thiab

qhia txog kev ruaj khov zoo heev rau ntau xyoo.

4) Yog tias qhov no yuav siv los ua cov khoom siv tiv taus qhov tseeb, kev kho cua sov qis yog qhov tsim nyog
yuav tsum tau tshem tawm cov kev ua haujlwm tsis zoo ib yam li hauv cov ntaub ntawv ntawm Manganin wire CMW.
