Kenyelletso ea li-sensors tsa Ultrasonic
Li-sensor tsa Ultrasonic ke li-sensor tse ntlafalitsoeng ho sebelisoa litšobotsi tsa ultrasound.Li-sensor tsa Ultrasonic li sebelisa phello ea piezoelectric ea li-ceramics tsa piezoelectric.Ha lets'oao la motlakase le sebelisoa ho poleiti ea ceramic ea piezoelectric, e tla holofala, e etse hore sensor e thothomele le ho ntša maqhubu a ultrasonic.Ha ultrasound e otla tšitiso, e bonahatsa morao 'me e sebetsa holim'a poleiti ea ceramic ea piezoelectric ka sensor.E ipapisitse le phello e fapaneng ea piezoelectric, sensor ea ultrasound e hlahisa tlhahiso ea lets'oao la motlakase.Ka ho sebelisa molao-motheo oa lebelo le sa khaotseng la ho hasana ha maqhubu a ultrasonic sebakeng se le seng, sebaka se pakeng tsa litšitiso se ka khethoa ho latela phapang ea nako pakeng tsa ho fetisa le ho amohela lipontšo.Maqhubu a Ultrasonic a tla hlahisa maikutlo a bohlokoa a ho bonahatsa ha a kopana le litšila kapa li-interfaces, le liphello tsa Doppler ha li kopana le lintho tse tsamaeang.Ka hona, li-sensor tsa ultrasonic li sebelisoa haholo indastering, ts'ebeliso ea sechaba, ts'ireletso ea naha, biomedicine le mafapha a mang.
Lisebelisoa
1. Radar ea likoloi tse thibelang ho thulana, tsamaiso ea mahlaseli a mahlaseli a kotsi, ultrasonic proximity switch;
2. Lisebelisoa tsa ho laola remoutu bakeng sa lisebelisoa tsa ka tlung, lipapali, le lisebelisoa tse ling tsa elektroniki;
3. Ultrasonic emission le lisebelisoa tsa kamohelo bakeng sa thepa e khahlanong le bosholu le ho thibela likoluoa.
4.E sebelisoa ho leleka menoang, likokoanyana, liphoofolo, joalo-joalo.
Litsebiso
1. Motlakase oa ultrasonic o hlahisa sefate sa ultrasonic ka lehlakoreng la 60 degree ka ntle, kahoo ha hoa lokela ho ba le litšitiso tse ling pakeng tsa probe le ntho e lekantsoeng.
2. Mojule oa ultrasonic o lekanya sebaka se otlolohileng pakeng tsa ntho e lekantsoeng le probe, 'me probe e lokela ho bolokoa e shebane le ntho e lekantsoeng nakong ea tekanyo.
3. Tekanyo ea Ultrasonic e susumetsoa ke lebelo la moea oa tikoloho, mocheso, joalo-joalo.
Litaba tse ka bang teng
1. Ka lebaka la tšusumetso ea ho se lekane ha ntho e lekantsoeng, angle ea ho bonahatsa, lebelo la moea oa tikoloho le mocheso, le lipontšo tse ngata, maqhubu a ultrasonic a ka eketsa liphoso tsa data ea tekanyo.
2. Ka lebaka la litšobotsi tsa tlhaho tsa ultrasound ho lekanya mabala a foufetseng, haeba boemo ba tekanyo bo fetoha 'me data e amoheloang e lula e sa fetohe nakong ea tekanyo e haufi, e bontša hore sebaka se foufetseng sa tekanyo se kentsoe.
3. Haeba ho se na data ea tekanyo e khutlisetsoang ha mojule o metha lintho tse hole, e ka 'na ea ba ka ntle ho tekanyo ea tekanyo kapa angle ea tekanyo e ka 'na ea se ke ea nepahala.Tekanyo ea ho lekanya e ka fetoloa ka nepo.
