Medical ultrasound transducer probe L38 izindlu
Ixesha lokuzisa: Kwimeko ekhawulezayo enokwenzeka, siya kuthumela iimpahla kwangolo suku lunye emva kokuba uqinisekise ibango lakho. Ukuba imfuno inkulu okanye kukho iimfuno ezikhethekileyo, kuya kumiselwa ngokusekelwe kwimeko yangempela.
Ubungakanani bendlu ye-L38 probe:
Iimpawu zokusebenza ze-ultrasonic sensors:
Ingundoqo ye-ultrasonic probe yi-chip piezoelectric. Ii-wafers zingenziwa ngeentlobo ezininzi zezinto. Ubungakanani be-chip, obufana nobukhulu kunye nobukhulu, bukwahluka, ngoko ukusebenza kweprobe nganye kuyahluka, kwaye kufuneka siqonde ukusebenza kwayo kwangaphambili ngaphambi kokusetyenziswa. Iimpawu eziphambili zokusebenza ze-ultrasonic sensors ziquka:
1.Ukusebenza rhoqo - yi-resonant frequency ye-piezoelectric chip. Xa i-frequency ye-voltage ye-AC esetyenziswe kuzo zombini iziphelo ilingana ne-resonant frequency ye-chip, amandla aphumayo aphezulu kwaye uvakalelo nalo luphezulu.
2.Ukushisa okusebenzayo - Ekubeni indawo yeCurie yezinto ze-piezoelectric iphezulu kakhulu, ngakumbi i-diagnostic ultrasonic probes esebenzisa amandla amancinci, ukushisa okusebenzayo kuphantsi kwaye kunokusebenza ixesha elide ngaphandle kokusilela. Iiprobe ze-ultrasound zonyango zinamaqondo obushushu aphezulu kwaye zifuna izixhobo zesikhenkcisi esahlukileyo.
3.Uvakalelo - ikakhulu kuxhomekeke kwi-wafer yokuvelisa ngokwayo. Ukuba i-coefficient yokudibanisa i-electromechanical inkulu, uvakalelo luphezulu; ngokuchaseneyo, uvakalelo luphantsi.
