Lub hauv paus ntsiab lus ntawm Eddy Current Measurement for Coating Thickness Gauge
High zaus AC teeb liab tsim cov electromagnetic teb nyob rau hauv qhov kev sojntsuam kauj, thiab thaum lub sojntsuam nyob ze rau tus neeg xyuas pib, eddy tam sim no yog tsim nyob rau hauv nws. Qhov ze dua ntawm eddy tam sim no thickness gauge taub hau yog mus rau conductive substrate, qhov ntau dua eddy tam sim no thiab ntau dua qhov kev xav impedance. Qhov kev tawm tswv yim no sawv cev rau qhov kev ncua deb ntawm qhov kev sojntsuam thiab cov khoom siv hluav taws xob, uas yog lub thickness ntawm cov txheej uas tsis yog-conductive ntawm cov conductive substrate. Vim lub fact tias hom eddy tam sim no thickness gauge lub taub hau yog tshwj xeeb tsim los ntsuas lub thickness ntawm txheej ntawm non ferromagnetic hlau substrates, nws yog feem ntau hu ua ib tug tsis sib nqus gauge taub hau. Lub taub hau ntsuas tsis sib nqus ntawm cov eddy tam sim no thickness gauge siv high-frequency cov ntaub ntawv raws li lub coil core, xws li platinum nickel alloy los yog lwm yam ntaub ntawv tshiab. Piv nrog rau lub hauv paus ntsiab lus ntawm magnetic induction, qhov sib txawv tseem ceeb yog qhov kev sojntsuam sib txawv, qhov zaus ntawm lub teeb liab sib txawv, thiab qhov loj thiab qhov sib txawv ntawm cov teeb liab sib txawv. Zoo li cov hlau nplaum induction thickness gauge, eddy tam sim no thickness gauge kuj ua tiav ib qho kev daws teeb meem ntawm 0.1um, qhov kev tso cai yuam kev ntawm 1%, thiab qib siab ntau ntawm 10mm.
Ib txheej txheej thickness gauge siv lub hauv paus ntsiab lus ntawm eddy tam sim no tuaj yeem ntsuas cov txheej txheem uas tsis yog txheej txheem ntawm txhua yam khoom siv, xws li xim, txheej yas, thiab anodic oxide zaj duab xis rau ntawm qhov chaw ntawm lub dav hlau dav hlau, tsheb, khoom siv hauv tsev, aluminium alloy qhov rooj thiab qhov rais, thiab lwm yam khoom siv aluminium. Cov khoom siv txheej txheej muaj qee qhov kev coj ua, uas tuaj yeem ntsuas los ntawm kev ntsuas, tab sis qhov sib piv ntawm cov conductivity ntawm ob yuav tsum muaj tsawg kawg yog 3-5 zaus sib txawv (xws li chromium plating ntawm tooj liab). Txawm hais tias cov hlau substrate kuj yog cov khoom siv hluav taws xob, nws tseem tsim nyog siv cov qauv sib nqus rau cov haujlwm zoo li no.
Daim ntawv thov thiab kev faib tawm ntawm txheej thickness gauges
Lub txheej thickness gauge yuav muab faib ua
Sib nqus thickness gauge thiab non magnetic thickness gauge (ie eddy tam sim no txheej thickness gauge)
Txoj kev ntsuas magnetic thickness tuaj yeem ntsuas lub thickness ntawm tag nrho cov hlau tsis sib nqus thiab tag nrho cov txheej txheem uas tsis yog txheej txheem ntawm cov hlau thiab hlau sib nqus hlau, xws li tooj liab, zinc, chromium, kub, nyiaj, thiab lwm yam. , roj hmab, phosphating zaj duab xis, fiberglass, thiab lwm yam.
Eddy tam sim no txheej thickness gauge tuaj yeem ntsuas qhov tuab ntawm cov hlau tsis muaj hlau nplaum, xws li xim txheej, oxide zaj duab xis, phosphating films, fiberglass, roj hmab, thiab lwm yam txheej ntawm stainless hlau, tooj liab, thiab txhuas hlau.
