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. ltrasonic emission thiab txais khoom siv rau kev tiv thaiv tub sab nyiag thiab kev tiv thaiv kev puas tsuaj.
4.Siv los tsav yoov tshaj cum, kab, tsiaj, thiab lwm yam.
