25KHZ 16mm piezoelectric ultrasonic sensor
Izici
1.1) Vula isakhiwo
1.2) Isisindo esihlangene nesilula
1.3) Ukuzwela okuphezulu nokucindezela komsindo
1.4) Ukusetshenziswa kwamandla okuncane
1.5) Ukuthembeka okuphezulu
I-1625T I-Ultrasonic transmitter iyingxenye eyinhloko yethuluzi elixosha izinambuzane lika-elekthronikhi elisebenzisa isekethe ye-ultrasonic enemvamisa ephezulu nemvamisa eshanelayo ukuze ikhiqize amaza e-ultrasonic ashanelayo angu-22-55KHZ.Ucwaningo lwesayensi luthole ukuthi izinambuzane ezifana nomiyane, amaphela, namagundane zingabangela ukuphazamiseka ohlelweni lwazo lwe-endocrine kanye nemisebenzi yomzimba ngaphakathi kwalolu chungechunge lwemvamisa, ngaleyo ndlela zithole umphumela wokuxosha nokubulala.

Isingeniso Sezinzwa ze-Ultrasonic
Izinzwa ze-Ultrasonic izinzwa ezakhiwe kusetshenziswa izici ze-ultrasound.Izinzwa ze-Ultrasonic zisebenzisa umphumela we-piezoelectric we-piezoelectric ceramics.Uma isignali kagesi isetshenziswa epuleti le-ceramic ye-piezoelectric, izokhubaza, ibangele inzwa ukuthi idlidlize futhi ikhiphe amagagasi e-ultrasonic.Uma i-ultrasound ishaya isithiyo, ikhombisa emuva futhi isebenza kupuleti le-ceramic le-piezoelectric ngokusebenzisa inzwa.Ngokusekelwe kumphumela we-piezoelectric ophambene, inzwa ye-ultrasound ikhiqiza okukhipha isignali kagesi.Ngokusebenzisa isimiso sejubane eliqhubekayo lokusakaza lamagagasi e-ultrasonic endaweni efanayo, ibanga phakathi kwezithiyo linganqunywa ngokusekelwe kumehluko wesikhathi phakathi kokudlulisa nokwamukela amasignali.Amagagasi e-Ultrasonic azokhiqiza ama-reflection echoes abalulekile lapho ehlangana nokungcola noma ukuxhumana, kanye nemiphumela ye-Doppler lapho ehlangana nezinto ezihambayo.Ngakho-ke, izinzwa ze-ultrasonic zisetshenziswa kabanzi ezimbonini, ukusetshenziswa kwezakhamuzi, ukuvikela izwe, i-biomedicine, nakweminye imikhakha.
Izinhlelo zokusebenza
1. I-radar ye-Automotive anti-collision, i-ultrasonic esukela uhlelo, i-ultrasonic proximity switch;
2. Imishini yokulawula kude yemishini yasendlini, amathoyizi, nezinye izinto zikagesi;
3. Ukukhishwa kwe-Ultrasonic kanye nemishini yokwamukela imishini yokulwa nokweba kanye neyokuvimbela izinhlekelele.
4.Isetshenziselwa ukuxosha omiyane, izinambuzane, izilwane, njll.
