Eddy tam sim no ntsuas txoj cai ntawm tsheb xim txheej thickness gauge tsheb xim electroplate hlau txheej thickness tester meter 0-1500um Fe & NFe sojntsuam
Lub high-frequency AC teeb liab generates ib tug electromagnetic teb nyob rau hauv lub 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 ntawm qhov kev sojntsuam yog mus rau qhov conductive substrate, qhov ntau dua qhov eddy tam sim no thiab ntau dua qhov kev xav impedance.
Qhov kev tawm tswv yim no qhia txog qhov kev ncua deb ntawm qhov kev sojntsuam thiab cov khoom siv hluav taws xob, uas yog, lub thickness ntawm cov txheej txheem uas tsis yog-conductive ntawm lub conductive substrate. Txij li cov kev sojntsuam no tshwj xeeb hauv kev ntsuas qhov tuab ntawm cov txheej txheem ntawm cov hlau tsis-ferromagnetic substrates, lawv feem ntau hu ua non-magnetic probes. Cov kev sojntsuam tsis sib nqus siv cov khoom siv ntau zaus ua cov coil cores, xws li platinum-nickel alloys lossis lwm yam khoom 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, qhov loj thiab qhov sib txawv ntawm cov teeb liab sib txawv.
Lub thickness gauge siv lub hauv paus ntsiab lus ntawm eddy tam sim no nyob rau hauv lub hauv paus ntsiab lus ntsuas cov non-conductive txheej ntawm tag nrho cov hluav taws xob conductors, xws li cov nto ntawm aerospace tsheb, tsheb, khoom siv hauv tsev, aluminium alloy qhov rooj thiab qhov rais, thiab lwm yam khoom txhuas. Anodized zaj duab xis. Cov khoom siv cladding muaj qee yam conductivity, uas tuaj yeem ntsuas los ntawm calibration, tab sis qhov piv ntawm ob qhov conductivity yuav tsum muaj tsawg kawg yog 3-5 zaus sib txawv (xws li chrome plating ntawm tooj liab). Txawm hais tias steel substrate kuj yog ib qho hluav taws xob conductor, nws yog qhov tsim nyog los siv lub hauv paus ntsiab lus sib nqus rau hom haujlwm no.
