Iimbonakalo
1.1) Vula isakhiwo
1.2) Ubuncinci kunye nobunzima obulula
1.3) Uvakalelo oluphezulu kunye noxinzelelo lwesandi
1.4) Ukusetyenziswa kwamandla okuncinci
1.5) Ukuthembeka okuphezulu
I-1625T I-Ultrasonic transmitter yinxalenye engundoqo yesixhobo sombane esigxotha izinambuzane esisebenzisa i-high-frequency ultrasonic circuit kunye ne-tread frequency ukuvelisa i-22-55KHZ etshayela amaza e-ultrasonic.Uphando lwezenzululwazi lufumanise ukuba izinambuzane ezitshabalalisayo ezifana neengcongconi, amaphela, kunye neempuku zinokubangela ukuphazamiseka kwinkqubo yazo ye-endocrine kunye nemisebenzi ye-physiological ngaphakathi kolu luhlu lwamaza, ngaloo ndlela kufezekiswa isiphumo sokugxotha kunye nokubulala.

Intshayelelo kwi-Ultrasonic Sensors
Iinzwa ze-Ultrasonic zizivamvo eziphuhliswe ngokusebenzisa iimpawu ze-ultrasound.Iinzwa ze-Ultrasonic zisebenzisa umphumo we-piezoelectric we-piezoelectric ceramics.Xa isignali yombane isetyenziswe kwipleyiti ye-ceramic ye-piezoelectric, iya kuguqula, ibangele ukuba inzwa ishukume kwaye ikhuphe amaza e-ultrasonic.Xa i-ultrasound ibetha umqobo, ibonakalisa umva kwaye isebenze kwi-piezoelectric ceramic plate ngokusebenzisa inzwa.Ngokusekelwe kwi-inverse piezoelectric effect, i-sensor ye-ultrasound ivelisa imveliso yombane.Ngokusebenzisa umgaqo wesantya sokusasazwa rhoqo kwamaza e-ultrasonic kwindawo efanayo, umgama phakathi kwemiqobo unokumiselwa ngokusekelwe kwixesha eliphakathi kokudlulisa kunye nokufumana iimpawu.Amaza e-Ultrasonic aya kuvelisa i-echoes ephawulekayo yokubonakalisa xa edibana nokungcola okanye i-interfaces, kunye nemiphumo ye-Doppler xa bedibana nezinto ezihambayo.Ke ngoko, izinzwa ze-ultrasonic zisetyenziswa ngokubanzi kumashishini, ukusetyenziswa koluntu, ukhuselo lwelizwe, i-biomedicine, kunye namanye amacandelo.
Usetyenziso
1. I-radar ye-Automotive anti-collision radar, i-ultrasonic rangeing system, i-ultrasonic proximity switch;
2. Izixhobo zolawulo olukude lwezixhobo zendlu, iithoyi, kunye nezinye izixhobo zombane;
3. Ukukhutshwa kwe-Ultrasonic kunye nezixhobo zokwamkela izixhobo zokulwa nobusela kunye nokuthintela iintlekele.
4.Isetyenziselwa ukugxotha iingcongconi, izinambuzane, izilwanyana, njl.
