Txheej Thickness Gauge Calibration Considerations
Txheej thickness gauge calibration ceev faj, yuav tsum xyuam xim rau cov ntsiab lus hauv qab no:
1. Kev ntsuas kom raug yog qhov tseem ceeb rau kev ntsuas kom raug. Rau calibration, ib qho piv txwv zoo ib yam li cov khoom yuav ntsuas tom qab yuav raug siv, piv txwv li nyob rau tib lub sij hawm, tus qauv qauv thiab cov khoom yuav tsum tau ntsuas yuav tsum muaj tib yam duab thiab geometry. Feem ntau, cov qauv qauv ntau dua ntawm cov khoom ntsuas tau sib phim, qhov tseeb dua qhov ntsuas ntsuas yuav yog.
2. Nco ntsoov tias cov khoom nram qab no ntawm cov qauv ntsuas ntsuas thiab cov khoom yuav tsum ntsuas qhov sib tw: -- Radius ntawm curvature ntawm qhov chaw -- Substrate khoom (xws li permeability, conductance; qhov zoo tshaj plaws, tus qauv qauv thiab cov khoom ntsuas yuav tsum yog tib yam khoom) -- Substrate Thickness-- Qhov Loj Ntawm Qhov Ntsuas
3. Ua ntej pib lub calibration, xyuas kom meej tias lub calibration point, sensor tip thiab calibration template yog huv si. Yog tias tsim nyog, tshem tawm cov khoom tsim xws li roj, hlau shavings, thiab lwm yam. Txhua yam impurities tuaj yeem cuam tshuam rau qhov ntsuas thiab ua rau calibration instability.
4. Nco ntsoov nrhiav tib txoj haujlwm calibration rau txhua tus, tshwj xeeb tshaj yog rau kev ntsuas ntawm qhov me me thiab ntsuas ntawm cov npoo thiab cov ces kaum. Kev ntsuas ntsuas tau pom zoo rau qhov me me.
5. Khaws kom deb ntawm qhov muaj zog sib nqus thaum lub sij hawm calibration.
6. Ntau calibration standard thicknesses uas tuaj yeem ua tau raws li qhov xav tau thickness yuav ua rau calibration thiab ntsuas qhov tseeb dua.
7. Raws li cov txheej txheem electromagnetic induction, los ntsuas qhov tuab ntawm cov hlau tsis yog hlau txheej ntawm cov hlau lossis hlau substrates, yuav tsum tau kho ntau lub ntsiab lus. Cov txheej txheem tuab yuav tsum tau ua los ntawm cov hlau tib yam li cov khoom yuav tsum tau ntsuas tom qab.
8. Yog siv calibration foils, xyuas kom lawv muab tso rau hauv ib qho chaw tiaj tus ntawm cov khoom siv substrate. Cov huab cua nyob hauv qab ntawv yuav tsum tau zam vim qhov no yuav ua rau kev nyeem tsis raug. Nyob rau hauv cov ntaub ntawv ntawm curvilinear foils, xyuas kom meej tias lawv muab tso rau ntawm lub hauv paus.
9. Precision thickness gauges yuav tsum tau saib xyuas. Txhua qhov hnav thiab tsim kua muag ntawm tus qauv tuab yuav raug cuam tshuam raws li qhov ntsuas qhov ntsuas tsis raug. Tsis txhob quav cov ntawv calibration. Ib qho buckling yuav ua rau huab cua sib txawv hauv qab ntawv ci, ua rau kev nyeem tsis raug. Khaws cov thickness txheem huv si. Txhua yam roj, roj, plua plav lossis lwm yam pov tseg yuav tsum raug zam. Ib qho kev tsim ntawm aluminium ntawv ci yuav raug txiav txim siab tuab thiab yuav ua rau qhov kev ntsuas qhov yuam kev ntawm tib tus nqi raws li qhov tsim cov thickness. Txhawm rau muab lub tswv yim ntxhib rau koj: kev tsim cov ntiv tes yog txaus los ua qhov yuam kev ntxiv ntawm ob peb microns.
