Ntawv thov ultrasonic impedance analyzer
Cov chaw thov:
Qhov ntsuas no haum rau kev ntsuas ntau cov khoom siv ultrasonic, suav nrog: ultrasonic transducers, ultrasonic tshuab raj, ultrasonic pwm (lub taub hau cuab yeej), ywj siab piezoelectric ceramics, hloov pauv, tshuab ntxuav ultrasonic, ultrasonic yas welders, underwater acoustics, Cov ntaub ntawv Magnetostrictive, ultrasonic pulverizers, ultrasonic atomization , ultrasonic ntxuav hniav, thim rov qab radar, ntsuas ultrasonic nrug, phacoemulsification, ultrasonic descaling, ultrasonic motors, thiab tag nrho lwm cov khoom siv thiab cov khoom siv uas siv piezoelectric thiab ultrasonic.
Tshwj xeeb nyob rau hauv cov txheej txheem ntawm kev tshawb fawb thiab kev tsim kho thiab kev tsim cov cuab yeej siv ultrasonic, yuav ua li cas paub seb ultrasonic tiv thaiv cov khoom lag luam koom nrog tus engineer ua tau raws li qhov yuav tsum tau ua, nws qhov zoo, kev ua haujlwm, thiab qhov tsis dhau los, yuav tsum tau ntsuas los ntawm ultrasonic qhov ntsuas tsis haum ntsuas.
1. Transducer: Tsis muaj lub voj voog parasitic yuav tsum tshwm sim hauv lub vojvoog admittance, resonance impedance yuav tsum nyob ze rau qhov tsim impedance li sai tau, qhov cuam tshuam ntawm lub zog impedance yuav tsum tsawg, qhov zoo tshaj Qm yuav tsum nyob ze rau qhov tsim qauv tsim, thiab lub capacitance yuav tsum sib phim hauv Circuit Court.
2. Piezoelectric ceramic daim ntawv: qhov zoo ntawm lub cuab yeej tuaj yeem txiav txim ncaj qha los ntawm kab keeb kwm txaus sab kos duab thiab ua haujlwm logarithmic. Yog tias muaj lub delamination lossis cov kab nrib pleb rau sab hauv cov ntaub ntawv ceramic, logarithmic nkhaus yuav muaj ntau lub peaks, thiab daim kab lub cim keeb kwm zoo nkauj yuav tshwm ntau A parasitic me me.
3. Amplifier: Los ntawm cov qauv tsim, kev ua thiab sib sau ua ke, txawm hais tias nws yog qhov tsim nyog lossis tsis tuaj yeem tuaj yeem pom ncaj qha rau ntawm daim duab kos duab kos duab.
4. Kev tsim thiab ua cov tshuab ua haujlwm vuam tshuab ultrasonic: siv cov txiaj ntsig ntawm lub voj voos los soj ntsuam xyuas lub xeev ntawm lub tshuab vuam, thiab nrhiav cov teeb meem ntawm lub tshuab vuam los ntawm kev soj ntsuam ntawm cov tsis thiab cov duab.
5. Kev tsim khoom thiab ua tiav ntawm cov tshuaj ntxuav ultrasonic: Cov kev xaiv ntawm cov tseev kom yuav tsum tau lawv cov kev ua haujlwm kev co yog zoo ib yam li qhov ua tau (bandwidth, qhov zoo tshaj tawm, resonance impedance, dynamic impedance). Ntawm kab kos lub vajvoog admittance, yuav tsum tsis muaj kab lub parasitic kom ntau li ntau tau lossis tsis muaj kab npab parasitic nyob ze ntawm qhov chaw resonance. Nws tuaj yeem txheeb xyuas thiab ntsuas qhov tsis haum cov teeb meem ntawm kev hloov pauv kev tsim khoom, kev tshuaj xyuas kev tuaj xyuas, kev sib txuas hloov tshuab, thiab tshuab ntxhua khaub ncaws.
Lub tshuab ntsuas tag nrho ntawm lub tshuab ntxuav tuaj yeem ntsuas qhov resonance impedance thiab static capacitance ntawm lub tshuab kom phim cov khoom siv fais fab. Nws tuaj yeem txheeb xyuas cov yam ntxwv ntawm nws cov khoom tshiab resonance, impedance tom qab txhaj dej, capacitance thiab hom kev co ntawm tag nrho cov tshuab.
