Ultrasonic Transducer

Ultrasonic sensors yog cov sensors uas hloov ultrasonic cov cim rau lwm lub zog hluav taws xob (feem ntau cov cim hluav taws xob). Nthwv dej ultrasonic yog cov neeg kho tshuab yoj uas nws qhov kev co zaus siab tshaj 20kHz. Nws muaj cov yam ntxwv ntawm kev loj, luv ntaj luv, muaj qhov tshwm sim me me, tshwj xeeb tshaj yog cov kev taw qhia zoo, tuaj yeem dhau los ua cov duab tshav thiab cov kev taw qhia. Kev nkag mus ntawm cov kua thiab cov khib nyiab yog qhov zoo, tshwj xeeb tshaj yog nyob rau hauv kev tiv thaiv tshav ntuj opaque. Thaum ultrasonic yoj ntsib impurity lossis interface, nws yuav tsim kev xav txog qhov tseem ceeb thiab daim ntawv ncha, thiab thaum nws ntsib cov khoom txav mus los, nws yuav tsim cov teebmeem doppler. Ultrasonic sensors yog dav siv nyob rau hauv kev lag luam, kev tiv thaiv teb chaws, biomedicine thiab lwm cov teb.
