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.
