Nta
1.1) Qhib qauv
1.2) Compact thiab lub teeb yuag
1.3) Siab rhiab heev thiab lub suab siab
1.4) Tsawg zog siv
1.5) Kev ntseeg siab
1625T Ultrasonic transmitter yog ib feem ntawm cov khoom siv hluav taws xob tua kab hluav taws xob uas siv lub tshuab hluav taws xob ntau zaus ultrasonic nrog lub cheb zaus los tsim 22-55KHZ cheb zaus ultrasonic tsis.Kev tshawb fawb tshawb fawb tau pom tias cov kab tsuag xws li yoov tshaj cum, kab laum, thiab nas tuaj yeem ua rau muaj kev cuam tshuam hauv lawv cov kab mob endocrine thiab kev ua haujlwm ntawm lub cev hauv qhov ntau zaus, yog li ua tiav cov txiaj ntsig ntawm kev tawm tsam thiab tua.

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.
