Hloov Kho Tshuab rau Txheej Thickness Gauges
Tam sim no, txawm hais tias nws yog lub npe nrov lossis cov chaw tsim khoom zoo tib yam hauv tsev thiab txawv teb chaws, txoj kev ua haujlwm ntawm nws qhov ntsuas thickness yuav tsum tau ua cov kauj ruam hauv qab no:
1 Kev hloov kho xoom, uas yog, xoom hloov kho ntawm ib lub phaj xoom tshwj xeeb, lossis xoom hloov kho ntawm qhov qub substrate uas yuav tsum tau ntsuas;
2 Raws li kev ntsuas sib txawv ntawm cov khoom ntsuas, siv cov khoom ntsuas kom tsim nyog los kho tus nqi kom txo qhov ntsuas qhov yuam kev.
Raws li ib txwm muaj, tsis muaj teeb meem nrog txoj kev no thaum lub cuab yeej tshiab thiab siv, tab sis nws tsuas yog me ntsis nyuab dua.
Tab sis thaum qhov kev sojntsuam siv rau ib lub sijhawm, teeb meem tshwm sim. Kev ntsuas qhov tseeb ntawm peb cov cuab yeej raug txo qis thaum ua haujlwm.
Nws yog ib qho nyuaj rau tuav. Yog vim li cas nyob rau hauv lub hauv paus ntsiab lus ntawm cov khoom, uas yog ib tug tuag flaw, uas yog, lub sojntsuam siv ib tug hlau nplaum rau cua lub kauj.
Thaum ib tug tam sim no dhau los, ib tug magnetic teb yog generated, thiab no magnetic teb yog tsis xwm yeem.
Hmoov zoo, tam sim no muaj cov txheej txheem tshiab txheej thickness gauge, FT200 txheej thickness gauge, uas siv qhov tseeb magnetic sensing technology.
Qhov no yog qhov peb paub raws li Hall effect, nrhiav tau los ntawm Hall hauv 1879. Los ntawm kev kawm txog kev sib raug zoo ntawm Hall voltage thiab ua haujlwm tam sim no, ntsuas qhov sib nqus thiab sib nqus permeability ntawm electromagnet, thiab kawm txog kev sib raug zoo ntawm Hall voltage thiab magnetic field, Hall pom tias qhov sib txawv muaj peev xwm UH yog proportional rau qhov tam sim no siv IH thiab proportional rau qhov sib nqus induction siv B, Inversely proportional rau thickness d ntawm daim ntawv.
Qhov no magnetic teb ua tsis tu ncua. Thaum lub hauv paus ntsiab lus no yog siv rau lub txheej thickness gauge, tsis tas yuav tsum tau kho lub xeem daim. Tshwj xeeb tshaj yog thaum ntsuas arc lossis concave khoom, nws yooj yim dua thiab siv tau yooj yim dua.
