Hais txog kev ua hauj lwm hauv paus ntsiab lus ntawm txheej thickness gauge
Nrog rau kev nce qib ntawm thev naus laus zis, tshwj xeeb tshaj yog tom qab kev taw qhia ntawm microcomputer technology nyob rau hauv xyoo tas los no, lub thickness gauge siv magnetic method thiab eddy tam sim no txoj kev tau coj ib tug loj kauj ruam nyob rau hauv cov kev taw qhia ntawm miniaturization, txawj ntse, multi-function, high precision thiab practicality kauj ruam. Qhov kev daws teeb meem ntawm qhov ntsuas tau mus txog 0.1 micron, thiab qhov tseeb tuaj yeem ncav cuag 1 feem pua, uas tau txhim kho zoo heev. Nws muaj ntau yam kev thov, kev ntsuas dav dav, kev ua haujlwm yooj yim thiab tus nqi qis. Nws yog qhov siv dav tshaj plaws ntsuas ntsuas ntsuas hauv kev lag luam thiab kev tshawb fawb tshawb fawb.
Txoj kev tsis muaj kev puas tsuaj tsis ua rau cov txheej txheem los yog lub substrate puas, qhov kev tshawb nrhiav ceev ceev, thiab kev soj ntsuam ntau tuaj yeem ua rau kev lag luam. Ntsuas Cov Ntsiab Cai thiab Cov Cuab Yeej
1. Kev ntsuas lub hauv paus ntsiab lus ntawm kev sib nqus attraction quab yuam thiab thickness gauge * Qhov luaj li cas ntawm qhov attraction quab yuam ntawm cov hlau nplaum (sab laug) thiab cov hlau nplaum hlau yog proportional rau qhov kev ncua deb ntawm lawv, uas yog, lub thickness ntawm txheej. Siv lub hauv paus ntsiab lus no los ua ib lub thickness gauge, tsuav yog qhov sib nqus permeability sib txawv ntawm cov txheej thiab substrate loj txaus, nws tuaj yeem ntsuas tau. Muab hais tias feem ntau cov khoom lag luam raug stamped thiab tsim los ntawm cov qauv hlau thiab cov ntawv kub thiab txias dov, cov hlau nplaum thickness gauges yog siv dav tshaj plaws. Lub hauv paus qauv ntawm lub thickness gauge yog tsim los ntawm hlau nplaum hlau, relay caij nplooj ntoos hlav, nplai thiab nws tus kheej-stop mechanism. Tom qab cov hlau nplaum thiab cov khoom yuav tsum tau ntsuas yog attracted, lub ntsuas lub caij nplooj ntoos hlav yog maj elongated, thiab lub rub quab yuam yog maj nce. Thaum lub zog rub tawm 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 sib cais ntawm cov hlau nplaum. Cov khoom lag luam tshiab tuaj yeem ua qhov txheej txheem kev txiav txim siab no. Cov qauv sib txawv muaj ntau yam sib txawv thiab siv sijhawm.
Cov cuab yeej nta kev ua haujlwm yooj yim, muaj zog, tsis muaj hluav taws xob, tsis muaj calibration ua ntej ntsuas, thiab tus nqi qis, ua rau nws zoo tagnrho rau kev tswj xyuas qhov zoo hauv kev cob qhia.
2. Lub hauv paus ntsiab lus ntawm magnetic induction ntsuas Thaum siv lub hauv paus ntsiab lus ntawm magnetic induction, lub thickness ntawm txheej yog ntsuas los ntawm qhov loj ntawm cov hlau nplaum flux ntws mus rau hauv ferromagnetic substrate los ntawm kev sojntsuam los ntawm cov txheej txheem uas tsis yog ferromagnetic. Qhov loj ntawm qhov sib thooj magnetoresistance kuj tuaj yeem ntsuas los qhia qhov tuab ntawm txheej. Lub thicker lub txheej, qhov siab dua qhov sib nqus tsis kam thiab qis dua qhov sib nqus flux. Lub thickness gauge siv lub hauv paus ntsiab lus ntawm magnetic induction nyob rau hauv lub hauv paus ntsiab lus muaj lub thickness ntawm cov hlau nplaum conductive txheej ntawm cov hlau nplaum conductive substrate. Feem ntau, qhov sib nqus permeability ntawm lub substrate yuav tsum siab tshaj 500. Yog hais tias cov khoom siv cladding tseem sib nqus, nws yuav tsum muaj qhov sib txawv loj txaus hauv permeability los ntawm cov khoom siv hauv paus (xws li npib tsib xee plating ntawm steel). Thaum qhov kev sojntsuam nrog cov tub ntxhais mos coil muab tso rau ntawm cov qauv mus kuaj, qhov ntsuas tau txiav tawm qhov ntsuas tam sim no lossis kuaj teeb liab. Cov khoom thaum ntxov siv cov ntsuas ntsuas ntsuas ntsuas qhov loj ntawm qhov induced electromotive quab yuam, uas amplified lub teeb liab thiab ces qhia lub thickness ntawm txheej. Nyob rau hauv xyoo tas los no, cov thev naus laus zis tshiab xws li kev ua kom ruaj khov, lub sijhawm kaw, thiab kev them nyiaj kub tau raug qhia hauv kev tsim hluav taws xob, thiab cov teeb liab ntsuas tau hloov kho los ntawm magnetoresistance. Cov tsim kev sib xyaw ua ke kuj tau txais kev pom zoo thiab lub microcomputer tau qhia, uas ua kom zoo dua qhov ntsuas qhov tseeb thiab rov tsim dua tshiab (yuav luag qhov kev txiav txim ntawm qhov loj). Kev daws teeb meem ntawm niaj hnub magnetic induction thickness gauges tuaj yeem ncav cuag 0.1um, qhov kev tso cai yuam kev tuaj yeem ncav cuag 1 feem pua, thiab qhov ntau tuaj yeem ncav cuag 10mm. Lub hauv paus ntsiab lus sib nqus tuab tuaj yeem siv los ntsuas cov xim txheej ntawm cov hlau nto, txheej tiv thaiv ntawm cov plooj (porcelain) thiab enamel, txheej txheej ntawm cov yas thiab roj hmab, ntau yam tsis-ferrous hlau coatings xws li npib tsib xee-chromium, thiab ntau yam txheej tiv thaiv corrosion. . Coatings rau kev lag luam chemical thiab roj av. .
3. Txoj Cai ntawm Kev Ntsuas Tam Sim No
Lub siab zaus AC teeb liab tsim ib qho chaw electromagnetic nyob rau hauv lub coil sojntsuam, uas tsim eddy tam sim no nyob rau hauv lub sojntsuam raws li qhov kev sojntsuam mus txog rau tus neeg xyuas pib. Qhov ze ntawm qhov kev sojntsuam yog mus rau qhov conductive substrate, qhov loj dua cov eddy tam sim no thiab qhov ntau dua qhov cuam tshuam 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. Vim tias cov kev sojntsuam no tau tsim los ntsuas cov txheej tuab ntawm cov hlau tsis-ferromagnetic substrates, lawv feem ntau hu ua non-magnetic probes. Cov khoom tsis sib nqus siv cov khoom siv ntau zaus rau cov tub ntxhais coil, xws li platinum-nickel alloys lossis lwm yam khoom tshiab. Piv nrog rau lub hauv paus ntsiab lus ntawm kev sib nqus induction, qhov sib txawv tseem ceeb yog qhov kev sojntsuam sib txawv, lub teeb liab zaus sib txawv, thiab qhov loj thiab feem ntawm cov teeb liab sib txawv. Ib yam li qhov sib nqus induction thickness ntsuas, qhov ntsuas qhov ntsuas tam sim no kuj ua tiav qhov kev daws teeb meem siab ntawm 0.1um, qhov kev tso cai yuam kev ntawm 1 feem pua, thiab ntau yam ntawm 10mm. Lub thickness gauge siv lub eddy tam sim no txoj cai muaj peev xwm nyob rau hauv lub hauv paus ntsiab lus ntsuas tsis-conductor coatings rau tag nrho cov conductors, xws li xim, yas coatings thiab anodized zaj duab xis rau ntawm qhov chaw ntawm txhuas khoom xws li chaw shuttles, tsheb, khoom siv hauv tsev, aluminium alloy qhov rooj thiab qhov rais. . Cov khoom siv cladding muaj qee yam conductivity, uas tuaj yeem ntsuas los ntawm calibration, tab sis qhov piv ntawm cov conductivity ntawm ob 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 kev qhia, rau cov dej num zoo li no nws tsim nyog siv lub hauv paus ntsiab lus sib nqus rau kev ntsuas.
