Alloy 290/ C17200 Nickel-Tooj-Tooj Alloy Hlau Rau Potentiometers / Shunts

Qhov precision tsis kam Alloy manganin yog tshwj xeeb tshaj yog cov cim kub, siab ntev thermal EMF tiv thaiv tus tooj liab thiab cov khoom ua haujlwm zoo.
Txawm li cas los xij, ntau dua thermal loads hauv qhov chaw tsis-oxidizing yog tau. Thaum siv rau cov khoom siv precision resistors nrog qhov siab tshaj plaws, cov tsim tawm yuav tsum tau ua tib zoo ntsaws thiab daim ntawv thov kub yuav tsum tsis pub tshaj 60 ° C. Tshaj tshaj qhov ua haujlwm kub siab tshaj plaws hauv huab cua yuav ua rau drift tsim los ntawm oxidizing cov txheej txheem.thus, lub sij hawm ntev tau cuam tshuam. Raws li ib tug tshwm sim, qhov tsis kam raws li cov coefficient ntawm cov hluav taws xob tsis kam yuav hloov me ntsis. Nws kuj yog siv tau cov khoom siv tsawg dua cov khoom siv rau cov nyiaj siv rau cov khoom hlau nyuaj mounting.

Cov lus qhia
MANGANIN HLAU / CRUMH12NI2 Hlau Siv Hauv Rheostats, Desistors, Hlau Maneganin Hlau PVC13, 6J12, 6J11 Phaj 6
Manganin hlau hlau (cupro-Manganese Hlau) yog lub npe cim npe rau ib qho alloy ntawm feem ntau 86% tooj liab, 12% manganese, thiab 2-5% npib tsib xee.
Maneganin hlau thiab ntawv ci yog siv nyob rau hauv cov khoom lag luam resistor, tshwj xeeb yog Ammeterual DeWrts, vim hais tias ntawm nws tus pas nrig ntsuas kub thiab cov ntsiab lus ntev.

Daim ntawv thov ntawm manganin

MANAGIN NTAWV NYIAJ THIAB HLAU yog siv hauv kev tsim cov noob tiv thaiv, tshwj xeeb ammeter tsis tshua muaj nqi thiab lub sij hawm ntev.
Lub tooj liab-raws li cov cua kub tsis kam siv nyob rau hauv cov khoom siv hluav taws xob tsawg, thermal sib tshooj relay, thiab lwm yam khoom tsawg-voltage. Nws yog ib qho ntawm cov ntaub ntawv tseem ceeb ntawm cov khoom siv hluav taws xob tsawg. Cov ntaub ntawv tsim tawm los ntawm peb lub tuam txhab muaj cov yam ntxwv ntawm kev ua tau zoo muaj kev sib txawv thiab zoo tshaj qhov ruaj khov. Peb tuaj yeem muab txhua hom hlau puag ncig, tiaj thiab cov ntaub ntawv.
