Taw qhia rau Ultrasonic Sensors
Ultrasonic sensors yog sensors tsim siv cov yam ntxwv ntawm ultrasound.Ultrasonic sensors siv cov nyhuv piezoelectric ntawm piezoelectric ceramics.Thaum lub teeb liab hluav taws xob siv rau lub phaj piezoelectric ceramic, nws yuav deform, ua rau lub sensor vibrate thiab emit ultrasonic tsis.Thaum ultrasound tsoo ib qho teeb meem, nws xav rov qab thiab ua rau ntawm piezoelectric ceramic phaj los ntawm lub sensor.Raws li cov nyhuv piezoelectric inverse, lub ultrasound sensor generates hluav taws xob teeb liab tso zis.Los ntawm kev siv lub hauv paus ntsiab lus ntawm kev nthuav tawm tsis tu ncua ntawm ultrasonic nthwv dej hauv tib qhov nruab nrab, qhov kev ncua deb ntawm cov teeb meem tuaj yeem txiav txim siab raws li lub sijhawm sib txawv ntawm kev xa tawm thiab tau txais cov cim.Ultrasonic nthwv dej yuav ua kom muaj kev cuam tshuam tseem ceeb thaum lawv nkag mus rau hauv kev sib cuag nrog impurities lossis cuam tshuam, thiab Doppler cuam tshuam thaum lawv nkag mus rau hauv cov khoom txav.Yog li ntawd, ultrasonic sensors tau dav siv hauv kev lag luam, kev siv pej xeem, kev tiv thaiv hauv tebchaws, biomedicine, thiab lwm yam.
Daim ntawv thov
1. Automotive anti-kev sib tsoo radar, ultrasonic ranging system, ultrasonic sib thooj hloov;
2. Cov khoom siv tswj chaw taws teeb rau cov khoom siv hauv tsev, cov khoom ua si, thiab lwm yam khoom siv hluav taws xob;
3. Ultrasonic emission thiab txais khoom siv rau kev tiv thaiv tub sab nyiag thiab kev tiv thaiv kev puas tsuaj.
4.Siv los tua yoov tshaj cum, kab, tsiaj txhu, thiab lwm yam.
Daim ntawv ceeb toom
1. Lub ultrasonic emitter emits ib tug ultrasonic beam ntawm ib tug 60 degree kaum sab nraud, yog li yuav tsum tsis txhob muaj lwm yam teeb meem ntawm lub sojntsuam thiab cov khoom ntsuas.
2. Lub ultrasonic module ntsuas qhov ntsug nrug ntawm qhov ntsuas qhov ntsuas thiab qhov ntsuas ntsuas, thiab qhov ntsuas ntsuas yuav tsum tau muab ntsia rau ntawm qhov ntsuas thaum ntsuas.
3. Ultrasonic ntsuas yog cuam tshuam los ntawm ib puag ncig cua ceev, kub, thiab lwm yam.
Tej teeb meem tshwm sim
1. Vim yog qhov cuam tshuam ntawm qhov tsis sib xws ntawm cov khoom ntsuas, lub kaum sab xis rov qab, ib puag ncig cua ceev thiab kub, thiab ntau qhov kev xav, ultrasonic tsis tuaj yeem ua rau cov ntaub ntawv ntsuas yuam kev.
2. Vim yog cov yam ntxwv ntawm ultrasound hauv kev ntsuas qhov muag tsis pom kev, yog tias qhov ntsuas qhov chaw hloov pauv thiab cov ntaub ntawv tau txais tseem tsis hloov pauv thaum ntsuas qhov ze, nws qhia tau tias qhov ntsuas qhov muag tsis pom tau nkag mus.
3. Yog tias tsis muaj cov ntaub ntawv ntsuas rov qab thaum lub module ntsuas cov khoom nyob deb, nws yuav nyob sab nraud ntawm qhov ntsuas lossis qhov ntsuas lub kaum sab xis yuav tsis raug.Lub kaum sab xis ntsuas tuaj yeem hloov kho kom haum.
