Cov yam ntxwv ntawm kev ua nrog rau ultrasonic transducer
Nyob rau hauv ib txwm muaj xwm txheej, qhov ultrasonic transducer siv yuav tsum muaj qhov qhia ncaj ntse, zoo li kev siv lub teeb tsa hluav taws xob rau lub teeb pom kev zoo, uas yog qhov zoo rau kev tsom mus rau lub emission ntawm lub zog, kom tau txais cov hluav taws xob ntau dua-lub suab nrov thaum txais tos, thiab tseem uas pab rau kom paub qhov hom phiaj ntsuas kev txheeb xyuas. Cov kev coj ncaj qha ntawm kev hloov pauv ultrasonic muaj feem xyuam rau nws cov hluav taws xob nto loj, qauv, ua haujlwm zaus, thiab cov yam ntxwv ntawm lub suab xa mus nruab nrab. Feem ntau, cov kev qhia ncaj qha tuaj yeem siv los ua qhov cuam tshuam ntawm ultrasonic transducer:
Txog qhov kev sib kis ultrasonic transducer, qhov sib koom ua ke ntawm kev sib tham tau hais txog lub ntsiab lus square suab siab ntawm qee qhov zaus ntawm qhov chaw nyob deb ntawm cov kis ultrasonic transducer ntawm lub ntsiab axis suab siab ntawm kis lub suab nqaj thiab dhau ntawm kis thiab cov transducer Qhov sib piv ntawm lub ntsiab lus txhais tau hais tias lub suab raug siab ib yam ntawm cov raug ntawm ib qho chaw nrawm. Txog qhov tau txais ultrasonic transducer, nws yog hais txog qhov sib piv ntawm cov nqi square ntawm electromotive tsim tawm los ntawm lub suab nthwv dej ntawm qee qhov zaus raws cov kab tseem ceeb ntawm lub transducer mus rau cov xwm txheej tus nqi ntawm electromotive force generated los ntawm diffuse suab teb nrog tib zaus thiab tib lub hauv paus txhais tau hais tias square lub suab siab.
Qhov kev qhia tau ncaj qha ntawm ultrasonic transducer kuj tseem tuaj yeem hais tawm hauv qhov decibels (dB), uas yog hu ua qhov kev ntsuas ncaj qha, uas yog sib npaug ntawm cov logarithm ntawm qhov sib txawv ntawm qhov ntsuas tau sib npaug los ntawm 10. Rau cov khoom sib kis, qhov ntsuas qhov ntsuas tseem tuaj yeem yog hu ua directivity nce.
