1. Karma alloy

Karma alloy yog tsim los ntawm tooj liab, npib tsib xee, Aluminium thiab Hlau ua cov khoom tseem ceeb. Lub resistivity yog 2 ~ 3 zaug siab dua MENTONG. Nws muaj qis dua qhov kub coefficient ntawm kev ua haujlwm (TCR), qis thermal EMF piv rau tooj liab, kev ua haujlwm zoo ntawm lub sijhawm ntev thiab muaj zog tiv thaiv oxidation. Nws qhov chaw ua haujlwm kub yog dav dua MENTONG (-60 ~ 300ºC). Nws yog tsim rau ua zoo precision kuj ntsiab thiab strain.

2. Karma loj

Hlau: 0.01mm-10mm
Ribbon: 0.05 * 0.2mm-2.0 * 6.0mm
Sawb: 0.5 * 5.0mm-5.0 * 250mm
3. Cov yam ntxwv tshwj xeeb ntawm Karma kuj xaim

1) Pib nrog Nickel Chromium hluav taws xob cua sov hlau Chav Kawm 1, peb hloov qee qhov Ni nrog
Al thiab lwm cov ntsiab lus, thiab yog li ua tiav cov khoom siv tsis zoo nrog kev txhim kho
kuj kub coefficient thiab kub electromotive quab yuam tiv thaiv tooj liab.
Nrog rau qhov sib ntxiv ntawm Al, peb tau ua tiav hauv kev ua kom muaj zog tiv thaiv 1.2 npaug ntau dua
tshaj Nickel Chromium hluav taws xob hluav taws xob cua sov hlau Chav Kawm 1 thiab lub zog tensile 1.3 npaug ntau dua.

2) Qhov nruab nrab kub coefficient β ntawm Karmalloy hlau KMW tsawg heev, - 0.03 × 10-6 / K2,

thiab qhov ntsuas kub tsis kam hloov pauv yuav luag ib txoj kab ncaj nraim hauv qhov dav
qhov kub thiab txias.

Yog li ntawd, qhov kub coefficient yog teem rau qhov nruab nrab kub coefficient ntawm
23 ~ 53 ° C, tab sis 1 × 10-6 / K, qhov nruab nrab kub coefficient ntawm 0 ~ 100 ° C, kuj tuaj yeem
tau txais kev pom zoo rau qhov kub coefficient.

3) Electromotive quab yuam tiv thaiv tooj liab ntawm 1 ~ 100 ° C kuj me me, hauv qab + 2 μV / K, thiab

pom zoo stability nyob rau hauv ib lub sij hawm ntawm ntau xyoo.

4) Yog tias qhov no yuav tsum tau siv los ua cov khoom siv tsis zoo, kev kho cua sov qis yog
yuav tsum tau tshem tawm cov kev ua distortions ib yam li nyob rau hauv cov ntaub ntawv ntawm Manganin hlau CMW.
