25KHZ 16mm piezoelectric ultrasonic sensor
Vaega
1.1) Faiga tatala
1.2) Maoti ma mama mama
1.3) Maualuluga maaleale ma leo mamafa
1.4) Faʻaitiitia le faʻaaogaina o le eletise
1.5) Faʻalagolago maualuga
1625T Ultrasonic transmitter o se vaega autu o se mea faʻapipiʻi iniseti eletise lea e faʻaogaina ai le eletise eletise eletise maualuga ma le faʻaogaina o le tele e faʻatupu ai le 22-55KHZ saluina o galu ultrasonic.O su'esu'ega fa'asaienisi ua maua ai o fa'ama'i fa'ama'i e pei o namu, moa, ma isumu e mafai ona fa'alavelaveina ai a latou faiga fa'ai'au ma galuega fa'aletino i totonu o lenei va'aiga masani, ma maua ai le a'afiaga o le fa'asalaina ma le fasioti tagata.

Folasaga i le Ultrasonic Sensors
Ultrasonic sensors o masini e atiae e faʻaaoga ai uiga o le ultrasound.E fa'aogaina e le masini fa'aola le piezoelectric aafiaga ole piezoelectric ceramics.Pe a faʻaogaina se faʻailoga eletise i se piezoelectric plate ceramic, o le a faʻaleagaina, ma mafua ai ona tete le masini ma faʻaosoina galu ultrasonic.Pe a oso le ultrasound i se faʻalavelave, e toe faʻafoʻi i tua ma galue i luga o le piezoelectric plate ceramic e ala i le masini.Fa'avae i luga ole a'afiaga piezoelectric fete'ena'i, ole masini ultrasound e fa'atupuina ai se fa'ailoga eletise.E ala i le faʻaaogaina o le mataupu faavae o le saoasaoa faʻasalalau faifaipea o galu ultrasonic i le ala lava e tasi, o le mamao i le va o faʻalavelave e mafai ona fuafua e faʻavae i luga o le eseesega o le taimi i le va o le felauaiga ma le mauaina o faailo.O galu o le Ultrasonic o le a faʻaalia ai le tele o siʻule o mafaufauga pe a latou faʻafesoʻotaʻi ma mea leaga poʻo fesoʻotaʻiga, ma aafiaga Doppler pe a faʻafesoʻotaʻi ma mea feʻaveaʻi.O le mea lea, o masini ultrasonic e faʻaaogaina lautele i alamanuia, faʻaoga lautele, puipuiga a le atunuʻu, biomedicine, ma isi faʻalapotopotoga.
Talosaga
1. Radar anti-collision taʻavale, masini faʻapipiʻi ultrasonic, suʻega vavalalata ultrasonic;
2. Fa'atonuga mamao mo meaafale, meata'alo, ma isi masini fa'aeletoroni;
3. Ultrasonic emission ma le taliaina masini mo le anti-gaoi ma mea e puipuia ai faalavelave.
4. Faʻaaogaina e tuliesea ai namu, iniseti, manu, ma isi.
