Kev siv dav ntawm ultrasonic transducers
Ultrasonic transducers yog siv dav. Lawv tau faib ua kev lag luam, kev ua liaj ua teb, tsheb thauj mus los, nyob, kev kho mob thiab tub rog raws li kev lag luam uas lawv tau thov. Raws li lub luag haujlwm pom tau hais tias, nws tau muab faib ua ultrasonic ua haujlwm, kev tu ultrasonic, kuaj ultrasonic, kuaj pom, ntsuas xyuas, telemetry, chaw taws teeb tswj, thiab lwm yam; raws li kev ua haujlwm ntawm ib puag ncig, nws muab faib ua kua, roj av, cov kab mob muaj sia, thiab lwm yam.; los ntawm cov xwm txheej, nws tau muab faib ua lub zog hluav taws xob, kuaj pom ultrasound, ntsuas ultrasound, thiab lwm yam.
Kev tshuaj xyuas kom paub-coj kev nyab xeeb
Hauv kev lag luam niaj hnub, nws yog qhov yuav tsum tau saib xyuas txoj kev khiav tsheb thiab suav cov tsheb kom txhawm rau nkag siab txoj haujlwm ntawm lub tsheb. Piv txwv li, chaw nres tsheb saib xyuas tsheb yog nruab nrog lub tshuab hluav taws xob ultrasonic thiab nws cov cuab yeej pabcuam rau kev sib kis thiab kev txais tos. Thaum lub tsheb hla dhau ntawm, ib lub tshuab raj acoustic rov qab los. Cov naj npawb ntawm cov tsheb txhua hnub tuaj yeem tau los ntawm kev suav thiab nce tsheb. Nruab lub tshuab hluav taws xob dual-siv transducer tom qab lub tsheb kom tiv thaiv tau qhov kev nrawm nraub qaum. Txais cov piezoelectric ultrasonic transducers ntawm txoj kev loj kuj tseem tuaj yeem saib cov suab nrov.
Cov ntaub ntawv sau-nkag mus hauv cov hnub nyoog ntse
Cov neeg txawj ntse yuav tsum paub qhov kev ua haujlwm ntawm kev taug kev ywj pheej hauv qhov chaw thiab paub txog cov khoom, tsis tsuas yog siv cov tshuab hloov ultrasonic los ntsuas qhov muag tsis pom kev, tab sis tseem txheeb xyuas cov duab. Yog li no, me me ultrasonic transducer array yog xav tau kom tau ntau lub zog.
Kws Kho Mob Tshuaj — —— Ultrasonic Poob
Siv lub tshuab ua kom cov ultrasonic hloov pauv hauv qhov cavitation effect thiab micro-mechanical kev co, cov roj ntsha ua haujlwm ntau dhau ntawm tib neeg daim tawv nqaij tawg thiab tawm thiab tawm hauv lub cev kom ua tiav lub hom phiaj ntawm kev poob phaus thiab ua kom zoo dua. Nov yog cov cuab yeej tawm tshiab tshiab thoob ntiaj teb thaum xyoo 1990s.
