Sib nqus induction ntsuas txoj cai thickness gauge
Thaum siv lub hauv paus ntsiab lus ntawm magnetic induction, lub thickness ntawm txheej yog ntsuas los ntawm kev siv qhov loj ntawm cov hlau nplaum flux ntws los ntawm kev sojntsuam los ntawm cov txheej tsis-ferromagnetic thiab mus rau hauv ferromagnetic substrate. Cov sib nqus sib nqus kuj tseem tuaj yeem ntsuas los qhia cov txheej tuab. Lub thicker lub txheej, ntau dua qhov sib nqus tsis kam thiab qhov me me ntawm qhov sib nqus flux. Thickness gauges uas siv lub hauv paus ntsiab lus ntawm magnetic induction muaj peev xwm nyob rau hauv lub hauv paus ntsiab lus muaj lub thickness ntawm non-magnetic conductive coatings ntawm magnetic permeable substrates. Feem ntau, qhov sib nqus permeability ntawm cov khoom siv hauv paus yuav tsum siab dua 500. Yog hais tias cov ntaub ntawv txheej kuj yog sib nqus, qhov sib txawv ntawm cov hlau nplaum permeability los ntawm cov khoom siv hauv paus yuav tsum loj txaus (xws li npib tsib xee plating ntawm hlau). Thaum qhov kev sojntsuam nrog lub kauj nyob ib ncig ntawm cov tub ntxhais mos yog muab tso rau ntawm cov qauv uas tau sim, qhov ntsuas tau txiav tawm qhov ntsuas tam sim no lossis kuaj teeb liab. Cov khoom lag luam thaum ntxov siv lub ntsuas ntsuas ntsuas ntsuas qhov ntsuas qhov loj ntawm qhov cuam tshuam electromotive quab yuam. Qhov ntsuas tau nthuav dav lub teeb liab thiab tom qab ntawd qhia cov txheej tuab. Nyob rau hauv xyoo tas los no, kev tsim hluav taws xob hauv Circuit Court tau qhia txog cov thev naus laus zis tshiab xws li kev ua kom ruaj khov, theem ntsuas phoo, thiab qhov kub thiab txias, thiab magnetoresistance yog siv los hloov cov kev ntsuas ntsuas. Nws kuj tseem siv lub xeev-ntawm-tus-kos duab integrated circuits thiab qhia microcomputers, uas zoo heev txhim kho qhov ntsuas qhov tseeb thiab reproducibility (yuav luag los ntawm qhov kev txiav txim ntawm qhov loj). Niaj hnub nimno magnetic induction thickness gauges muaj kev daws teeb meem ntawm 0.1um, qhov kev tso cai yuam kev ntawm 1%, thiab ntsuas ntau ntawm 10 hli.
Lub hauv paus ntsiab lus sib nqus qhov ntsuas tuaj yeem siv los ntsuas cov xim txheej ntawm cov hlau nto, porcelain thiab enamel tiv thaiv txheej, yas thiab roj hmab coatings, ntau yam tsis-ferrous hlau plating txheej xws li npib tsib xee thiab chromium, thiab ntau yam kev tiv thaiv corrosion nyob rau hauv lub chemical thiab petroleum industries. txheej.
