Medical ultrasound transducer probe L38 nyumba
Nthawi yoperekera: Munthawi yachangu kwambiri, tidzatumiza katundu tsiku lomwelo mutatsimikizira zomwe mukufuna. Ngati chofunacho chili chachikulu kapena pali zofunikira zapadera, zidzatsimikiziridwa malinga ndi momwe zilili.
Kukula kwa nyumba ya L38:
Zizindikiro za ma ultrasonic sensors:
Pakatikati pa kafukufuku wa akupanga ndi chipangizo cha piezoelectric. Zophika zimatha kupangidwa ndi mitundu yambiri yazinthu. Kukula kwa chip, monga m'mimba mwake ndi makulidwe, kumakhalanso kosiyana, kotero kuti ntchito ya kafukufuku aliyense ndi yosiyana, ndipo tiyenera kumvetsetsa momwe imagwirira ntchito pasadakhale tisanagwiritse ntchito. Zizindikiro zazikulu zogwirira ntchito za masensa a ultrasonic ndi awa:
1.Ntchito pafupipafupi - ndi resonant pafupipafupi chip piezoelectric. Pamene mafupipafupi a AC voteji yogwiritsidwa ntchito kumapeto onsewa ndi ofanana ndi ma frequency a resonant a chip, mphamvu yotulutsa mphamvu imakhala yochuluka komanso kukhudzidwa ndipamwamba kwambiri.
2.Kutentha kwa ntchito - Popeza kuti Curie mfundo ya zida za piezoelectric nthawi zambiri imakhala yokwera, makamaka ma probe akupanga omwe amagwiritsa ntchito mphamvu zochepa, kutentha kwa ntchito kumakhala kochepa kwambiri ndipo kumatha kugwira ntchito kwa nthawi yayitali popanda kulephera. Medical ultrasound probes ndi kutentha kwambiri ndipo amafuna osiyana firiji zipangizo.
3.Sensitivity - makamaka zimadalira chophatikizira chopangira chokha. Ngati electromechanical coupling coefficient ndi yaikulu, tilinazo ndi mkulu; m'malo mwake, chidwi ndi chochepa.
