Impedance analyzer tuaj yeem ntsuas qhov tseeb hauv qhov impedance ntau thiab ntau zaus ntau yam, nws siv cov khoom siv tau muaj hluav taws xob sib txawv, thaum tus nplaim khoom ntxiv qhov tsis hloov tam sim no, laij ntau yam khoom siv, cov khoom siv thiab cov haujlwm ntawm cov khoom los ntawm impedance.
Daim ntawv thov ntawm impedance curves thiab kev lees lub voj nyob hauv kev ua thiab ntau lawm ntawm cov khoom siv ultrasonic yog li hauv qab no:
Ultrasonic transducer: Lub vajvoog admittance tsis tuaj yeem pom parasitic lub voj voog, lub suab nrov ceev tau ze li sai tau ntawm qhov tsim zaus, qhov tsis zoo impedance tsawg, qhov zoo tshaj plaws Qm yuav tsum nyob ze rau qhov tsim qauv tsim, thiab lub capacitance yuav tsum sib phim hauv Circuit Court Cov.
Piezoelectric ceramic daim ntawv: qhov zoo thiab qhov tsis zoo ntawm cov cuab yeej tuaj yeem txiav txim ncaj qha los ntawm daim duab kos lees zoo hauv lub voj voos kos duab thiab cov logarithmic. Yog tias muaj delamination sab hauv cov ntawv ceramic lossis keej tshwm sim, lub logarithmic nkhaus yuav tshwm sim ntau lub ncov. Ntau qhov kab mob parasitic me me tshwm rau ntawm daim kab ke lees paub.
Ultrasonic tshuab raj thiab pwm: Txawm hais tias tus qauv tsim, kev ua thiab kev sib dhos yog qhov tsim nyog lossis tsis xws luag, tuaj yeem pom meej meej los ntawm daim ntawv lees paub.
Ultrasonic vuam tshuab: Thaum lub sijhawm kev tsim khoom thiab kev ua, lub xeev ntawm vuam tshuab tau raug txheeb xyuas los ntawm cov txiaj ntsig ntawm kev lees hauv lub voj voos, thiab cov teeb meem ntawm lub tshuab vuam raug pom los ntawm cov kev ntsuas thiab cov duab tsom xam.
5. Lub tshuab tu ultrasonic: Thaum tsim thiab ua, xaiv cov vibrator yuav tsum tau ua kom pom kev tshee tshee ua kom tau raws li qhov ua tau (bandwidth, qhov zoo tshaj plaws, qhov hloov siab zaus, qhov hloov tsis haum). Ntawm kab kos cov kab ntawv lees paub, muaj ob peb lub parasitic voj tau los sis tsis muaj lub voj voog parasitic nyob ze rau qhov resonance point. Los ntawm daim kab ke lees paub, lub tshuab hloov pauv tuaj yeem tsim khoom, tshuaj xyuas khoom, kev sib hloov khoom, thiab ntxuav lub tshuab rau impedance tsom xam thiab ntsuas. Lub tshuab ntsuas tag nrho ntawm lub tshuab ntxuav tuaj yeem ntsuas qhov ntsuas hluav taws xob zoo li qub ntawm lub tshuab hluav taws xob kom haum rau lub zog hluav taws xob, thiab tuaj yeem txheeb xyuas nws qhov chaw tshiab, cov impedance tom qab dej txhaj, cov capacitance thiab hom kev co ntawm lub tshuab tag nrho Cov.
