Medical ultrasound transducer probe L38 housing
Nako ea thomello: Boemong bo potlakileng ka ho fetesisa, re tla romella thepa ka letsatsi le le leng ka mor'a hore u netefatse tlhoko ea hau.Haeba tlhokahalo e kholo kapa ho na le litlhoko tse khethehileng, e tla khethoa ho latela maemo a sebele.
L38 probe boholo ba ntlo:
Matšoao a ts'ebetso ea li-sensor tsa ultrasonic:
Motheo oa probe ea ultrasonic ke chip ea piezoelectric.Li-wafers li ka etsoa ka mefuta e mengata ea thepa.Boholo ba chip, joalo ka bophara le botenya, bo boetse bo fapane, kahoo ts'ebetso ea probe ka 'ngoe e fapane,' me re tlameha ho utloisisa ts'ebetso ea eona esale pele pele e sebelisoa.Matšoao a mantlha a ts'ebetso ea li-sensor tsa ultrasonic li kenyelletsa:
1.Maqhubu a ho sebetsa - ke maqhubu a resonant a chip ea piezoelectric.Ha maqhubu a motlakase oa AC a sebelisoang lipheletsong ka bobeli a lekana le maqhubu a resonant a chip, matla a tsoang a phahame haholo 'me kutloisiso e boetse e phahame ka ho fetisisa.
2.Mocheso o sebetsang - Kaha ntlha ea Curie ea lisebelisoa tsa piezoelectric ka kakaretso e batla e phahame, haholo-holo li-diagnostic ultrasonic probes tse sebelisang matla a fokolang, mocheso o sebetsang o batla o le tlaase 'me o ka sebetsa nako e telele ntle le ho hlōleha.Lisebelisoa tsa bongaka tsa ultrasound li na le mocheso o batlang o le holimo 'me li hloka lisebelisoa tse arohaneng tsa sehatsetsi.
3.Sensitivity - haholo-holo e itšetlehile ka sephaphatha sa tlhahiso ka boeona.Haeba coefficient electromechanical coupling e kholo, kutloisiso e phahame;ho fapana le hoo, kutloisiso e tlase.
