Raws li ib qho ntawm cov cuab yeej siv feem ntau siv hauv cov chaw sim tshuaj lom neeg, qhov kev txiav txim siab tawg kom qhuav qhov cub yog qhov yooj yim thiab siv dav, Yog li kev xaiv tseem ceeb heev. Lub tshuab ziab khaub ncaws kom qhuav yog ib hom me me ntawm qhov cub, thiab nws kuj yog qhov yooj yim ci qhov kub thiab txias. Qhov kev ua haujlwm kub ntawm qhov precision moj tej tawg ziab qhov cub muaj xws li cov hauv qab no tseem ceeb tsis:
1/Kev tswj qhov kub thiab txias.
Feem ntau, kev tswj qhov kub thiab txias ntawm qhov ntsuas qhov ntsuas kub yog RT + 10 ~ 250 degrees. Nco ntsoov tias RT stands rau chav tsev kub, nruj me ntsis hais lus, nws txhais tau tias 25 degrees, uas txhais tau hais tias chav tsev kub, uas yog, qhov kub thiab txias ntawm lub moj tej tawg ziab qhov cub Qhov ntau yog 35 ~ 250 degrees. Tau kawg, yog tias qhov ntsuas kub ntawm ambient siab dua, qhov ntsuas kub tswj yuav tsum tau nce ntxiv raws li. Piv txwv li, yog tias qhov ntsuas kub nyob ib puag ncig yog 30 degrees, qhov ntsuas qhov tsawg kawg nkaus uas tso cai rau tswj tau yog 40 degrees, thiab yuav tsum tau ntsuas qhov ntsuas kub tsawg.
2/Kub uniformity.
Qhov kub tsis sib xws ntawm lub tshuab ziab khaub ncaws ua tau raws li "GBT 30435-2013" hluav taws xob cua sov kom qhuav qhov cub thiab hluav taws xob cua sov tshuab ziab kom qhuav qhov cub specifications, qhov tsawg kawg nkaus yuav tsum tau yog 2.5%, qhov specification no muaj cov ncauj lus kom ntxaws algorithm, piv txwv li, piv txwv li. Qhov kub ntawm qhov cub yog 200 degrees, ces qhov tsawg kawg nkaus ntawm qhov ntsuas qhov ntsuas yuav tsum tsis txhob qis dua 195, thiab qhov kub siab tshaj plaws yuav tsum tsis txhob siab tshaj 205 degrees. Qhov kub tsis sib xws ntawm qhov cub yog feem ntau tswj ntawm 1.0 ~ 2.5%, thiab qhov sib xws ntawm qhov cub kom qhuav yog feem ntau txog 2.0%, siab dua 1.5%. Yog tias qhov tsis sib xws ntawm tsawg dua 2.0% yog xav tau, nws raug nquahu kom siv lub qhov cub kub cua txias.
3/Kub hloov pauv (stability).
Qhov no yog hais txog qhov hloov pauv ntawm qhov ntsuas kub taw tes tom qab qhov kub thiab txias tau nyob tas li. Qhov kev qhia tshwj xeeb yuav tsum tau ntxiv lossis rho tawm 1 degree. Yog tias nws zoo, nws tuaj yeem yog 0.5 degree. Qhov no tuaj yeem ua tau los ntawm kev soj ntsuam qhov ntsuas. Feem ntau, tsis muaj qhov sib txawv ntau.
