Cov lus piav qhia luv luv thiab lub hauv paus ntsiab lus ua haujlwm ntawm qhov sib nqus tuab ntsuas
Qhov sib nqus thickness ntsuas muaj cov qauv ntsuas kev sib xyaw thiab tuaj yeem ua haujlwm nrog ib txhais tes. Nws siv lub hauv paus ntsiab lus ntawm electromagnetic induction thiab yog tsim rau kev ntsuas lub thickness ntawm non-magnetic npog txheej ntawm ntau yam hlau nplaum substrates.
Nws tuaj yeem ntsuas qhov tuab ntawm ntau yam plating (tshwj tsis yog npib tsib xee plating), coatings, enamels, yas thiab lwm yam txheej txheej ntawm cov hlau. Nws kuj tseem tuaj yeem siv los ntsuas ntau cov ntawv hlau (xws li tooj liab ntawv, aluminium ntawv ci, ntawv ci kub, thiab lwm yam) thiab cov yeeb yaj kiab uas tsis yog xim hlau (xws li ntawv, yas, thiab lwm yam) tuab. Cov cuab yeej no tuaj yeem siv rau kev tshuaj xyuas ntau lawm, kev lees paub tshuaj xyuas thiab kev tshuaj xyuas zoo. Raws li lub teb chaws tus qauv.
Muaj ob hom magnetic thickness gauges, ib tug hu ua magnetic thickness gauge thiab lwm yam yog hu ua magnetic induction thickness gauge.
Qhov sib nqus tuab ntsuas tuaj yeem ntsuas qhov tuab ntawm txheej txheej los ntawm qee qhov kev sib piv ntawm kev sib nqus ntawm cov hlau nplaum sojntsuam thiab cov hlau nplaum permeable substrate thiab qhov kev ncua deb ntawm ob.
Lub hauv paus ntsiab lus ntawm kev sib nqus induction yog siv qhov loj ntawm magnetic flux uas qhov kev sojntsuam dhau los ntawm cov txheej txheem uas tsis yog-ferromagnetic thiab ntws mus rau hauv cov hlau substrate los ntsuas qhov tuab ntawm txheej. Lub thicker lub txheej, qhov me me qhov ntsuas flux, thiab tom qab ntawd cov txheej txheej yog hloov los ntawm kev ua.
Lub zog quab yuam ntawm cov hlau nplaum (xws li) thiab cov hlau nplaum permeable yog proportional rau qhov kev ncua deb ntawm ob. Qhov kev ncua deb no yog lub thickness ntawm txheej.
Lub thickness gauge ua siv lub hauv paus ntsiab lus ntawm ib tug magnetic thickness gauge yog ib tug magnetic thickness gauge. Ntev npaum li qhov sib txawv ntawm qhov sib nqus permeability ntawm cov txheej thiab cov khoom siv hauv paus loj txaus, nws tuaj yeem ntsuas tau. Txij li feem ntau cov khoom lag luam raug stamped los ntawm cov qauv hlau thiab kub-kuav los tiag thiab txias-kuav los tiag steel daim hlau, magnetic thickness gauges yog siv dav tshaj plaws.
Lub hauv paus qauv ntawm cov hlau nplaum thickness gauge muaj cov hlau nplaum, relay caij nplooj ntoos hlav, nplai thiab nws tus kheej-stop mechanism.
Tom qab cov hlau nplaum yog nyiam rau cov khoom yuav tsum tau ntsuas, ntsuas lub caij nplooj ntoos hlav yog maj mam ncab thiab rub lub zog yog maj mam nce. Thaum lub zog rub tsuas yog ntau dua li lub zog nqus, lub thickness ntawm txheej tuaj yeem tau txais los ntawm kev kaw lub zog rub thaum lub sijhawm cov hlau nplaum raug tshem tawm.
Cov khoom lag luam tshiab tuaj yeem ua cov txheej txheem kaw cia. Cov qauv sib txawv muaj qhov ntsuas sib txawv thiab siv sijhawm.
Cov yam ntxwv ntawm cov cuab yeej no yog tias nws yooj yim rau kev khiav lag luam, ruaj khov thiab ruaj khov, tsis xav tau lub zog hluav taws xob, tsis tas yuav calibration ua ntej ntsuas, thiab yog tus nqi qis. Nws yog qhov tsim nyog rau kev tswj xyuas qhov zoo ntawm qhov chaw hauv kev cob qhia.
