3.Karma Property

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.
