Yuav ua li cas paub qhov txawv ntawm Ultrasonic Transducer thiab Ultrasonic sojntsuam?

Ultrasonic transducers siv cov ntaub ntawv piezoelectric ceramic los hloov hluav taws xob rau hauv lub zog txhua yam. Nyob rau hauv ib txwm muaj xwm txheej, lub yoj ultrasonic yog tsim los ntawm lub tshuab hluav taws xob ultrasonic, uas yog hloov mus rau hauv cov tshuab kev co los ntawm cov transducer, thiab tom qab ntawd cov yoj ultrasonic raug xa tawm los ntawm cov khoom xa tawm. Ultrasonic transducer ib leeg tsis tuaj yeem ua haujlwm, nws xav tau kev tsav tsheb los muab nws lub zog tsav los ua kom lub transducer ua haujlwm.

Ultrasonic sojntsuam, siv rau kev ntsuas nrug, yog lub hauv ntej kawg ntawm lub ultrasonic sensor. Nws yog siv los xa cov nthwv dej ultrasonic thiab tau txais lub suab tsis muaj kev cuam tshuam los ntawm qhov chaw ntawm cov khoom. Tshwj xeeb, nws yog ib feem ntawm ultrasonic sensor. Nyob rau hauv lwm yam lus, nws yog ib tug ultrasonic sojntsuam, uas feem ntau yog hais txog lub transducer nyob rau hauv lub sensor. Tsuas yog ib qho khoom siv hluav taws xob-acoustic hloov dua siab tshiab. Tus qauv teeb liab tsis tso zis.

Hauv kev siv tiag tiag, tsis muaj qhov txawv txav ntawm ob. Hauv qee qhov kev lag luam lossis qee lub sijhawm, cov npe kev cai yog qhov zoo ib yam, thaum lwm tus hu ua txawv vim yog cov tuam txhab sib txawv lossis tus cwj pwm ntawm tus kheej. Yog li ntawd, feem ntau, ultrasonic sensors thiab ultrasonic Ob transducers thiab ultrasonic probes yuav siv tau los xa mus rau tib yam.

1. Lub excitation teeb liab zaus ntawm lub ultrasonic transducer yog nyob ze rau lub resonance zaus, uas yog lub zog ua rau lub teeb liab.

2. Lub sensor yog ib tug passive tivthaiv, lub excitation teeb liab yuav tsim kev co, qhov kawg tau txais lub teeb liab, lub sij hawm ntev excitation (xws li nruam excitation 500 lub sij hawm) yuav tsis muaj teeb meem kev hloov.

3. Kev ua haujlwm ntawm lub sensor cuam tshuam los ntawm qhov kub thiab xav tau qhov kub thiab txias.

4. Qhov kev hloov ntawm qhov kub thiab txias tus yam ntxwv ntawm lub transducer yog reversible. Cov yam ntxwv hloov pauv tsis yog qhov loj, feem ntau yog vim qhov hloov pauv ntawm cov ntawv piezoelectric ceramic.

5. Tsim qauv ntawm ultrasonic transducer Circuit Court. Ultrasonic transducer yog ib lub zog hloov khoom siv tsim nyog los tsim cov ultrasonic tsis. Nws converts lub zog ntawm ultrasonic electromagnetic kev co mus rau hauv lub suab tsis. Ib qho ultrasonic transducer, tseem hu ua lub horn-shaped transducer, muaj cov yam ntxwv ntawm lub teeb yuag, me me, thiab lub zog siab.
