Piezoelectric Ultrasonic Transducers

Khoom piav qhia:

Ultrasonic sensors tuaj yeem ntes lub zog ntawm lub hom phiaj thiab ntsuas qhov kev ncua deb rau lawv hauv ntau lub tshuab ua haujlwm thiab cov txheej txheem cov nroj tsuag. Cov sensors tuaj yeem muaj qhov tso tawm los yog tawm digital rau kev kuaj xyuas qhov txav ntawm cov khoom, lossis cov khoom tso tawm analog piv rau qhov deb. Piezoelectric Ultrasonic Transducers tuaj yeem paub qhov ntug ntawm cov khoom siv raws li ib feem ntawm lub vev xaib kev taw qhia.

Piezoelectric Ultrasonic Transducers tau dav siv hauv tsheb ua chaw nres tsheb sensors los pab tus neeg tsav tsheb rov qab mus rau hauv qhov chaw nres tsheb. Lawv tab tom raug sim rau ntau lwm yam kev siv tsheb nrog rau kev tshawb nrhiav neeg ultrasonic thiab pab hauv kev tswj hwm tus kheej UAV navigation.

Vim tias Ultrasonic Transducers siv lub suab es tsis yog lub teeb rau kev kuaj pom, lawv ua haujlwm hauv cov ntawv thov uas photoelectric sensors yuav tsis. Ultrasonics yog ib qho kev daws teeb meem zoo rau kev tshawb pom cov khoom pom tseeb thiab rau kev ntsuas qib kua, kev siv uas photoelectrics tawm tsam nrog vim lub hom phiaj translucence. Ib yam li ntawd, lub hom phiaj xim lossis qhov cuam tshuam tsis cuam tshuam rau ultrasonic sensors, uas tuaj yeem ua haujlwm tau zoo hauv qhov chaw siab-glare.

Passive Ultrasonic Transducers tuaj yeem siv los kuaj xyuas cov pa roj los yog kua dej, lossis lwm yam kev phom sij uas tsim cov suab ultrasonic. Hauv cov khoom siv no, lub suab los ntawm lub tshuab hloov pauv (microphone) tau hloov mus rau tib neeg lub rooj sib hais.

High-power ultrasonic emitters yog siv nyob rau hauv kev muag khoom muaj ultrasonic tu li. Ib qho ultrasonic transducer yog affixed rau lub lauj kaub stainless hlau uas tau ntim nrog cov kuab tshuaj (feem ntau dej los yog isopropanol). Ib qho hluav taws xob square nthwv dej pub cov transducer, tsim lub suab hauv cov kuab tshuaj muaj zog txaus ua rau cavitation.

Ultrasonic tshuab tau siv rau ntau lub hom phiaj tu. Ib qho uas tau txais txiaj ntsig zoo ntawm kev sib tw hauv kaum xyoo dhau los yog kev ntxuav phom ultrasonic.

Ultrasonic kuaj transducer kuj tau siv dav hauv metallurgy thiab engineering los ntsuas corrosion, welds, thiab cov khoom siv tsis raug siv ntau hom kev soj ntsuam.

FAQ:

Lub ultrasonic transducer ua haujlwm li cas hauv lub tshuab nqus tsev ultrasonic?

Cov qauv ntawm Piezoelectric Ultrasonic Transducers yog feem ntau ib leeg ntsia hlau fastening longitudinal vibration ultrasonic transducers, uas yog tsim los ntawm ob piezoelectric ceramic wafers nrog lub hauv paus qhov thiab pem hauv ntej thiab nram qab daim hlau. Txhawm rau kom muaj kev ruaj ntseg thiab kev ua haujlwm ntawm cov cuab yeej ntawm lub tshuab ntxuav, ib qho kev ua haujlwm semi perforated dav band ultrasonic transducer kuj tau tsim. Cov yam ntxwv ntawm cov hom ultrasonic transducer no yog txhawm rau txhawm rau qee qhov ntawm qhov nrog qhov tob tib yam raws li cov kev taw qhia axial tusyees ntawm cov hluav taws xob saum npoo ntawm ultrasonic transducer los tsim cov qauv semi perforated. Ntawm lub qhov tob qhov tob, qhov loj dua qhov borehole txoj kab uas hla, qhov dav ntawm qhov ntau zaus band dav; Ntawm qhov chaw perforation tshwj xeeb, qhov tob ntawm lub qhov, qhov dav ntawm bandwidth. Hom ultrasonic transducer no yog hais txog ob npaug ntawm qhov dav dav ntawm ultrasonic transducer, uas tuaj yeem ncav cuag ± 2kHz, thiab nws cov electroacoustic efficiency tseem tuaj yeem tshaj 80% nyob rau hauv bandwidth, uas yog siab tshaj qhov dav dav ultrasonic transducer hauv electroacoustic ua hauj lwm efficiency, yog li daws. lub inconvenience tshwm sim los ntawm qhov nqaim bandwidth ntawm cov hom ultrasonic transducer nyob rau hauv lub high-power ultrasonic nqus tsev vacuum rau parallel ntau ultrasonic transducer. Lub semi perforated ultrasonic transducer tseem tuaj yeem txo qhov kev vibration ntawm cov hluav taws xob ntau, uas yog qhov zoo rau qhov nce ntawm cov hluav taws xob ntau ntawm cov high-frequency ultrasonic transducer thiab kev txhim kho cov khoom ua tau zoo ntawm cov khoom siv tu ultrasonic.
