Li-sensor tsa Hall li ipapisitse le phello ea Holo. The Hall effect ke mokhoa oa motheo oa ho ithuta thepa ea thepa ea semiconductor. Coefficient ea Holo e lekantsoeng ka liteko tsa phello ea Holo e ka tseba likarolo tsa bohlokoa joalo ka mofuta oa conductivity, mahloriso a motho ea tsamaisang thepa le motsamao oa thepa ea semiconductor.
Karolelano
Li-sensor tsa Holo li arotsoe ka li-sensor tsa Hall tse melang le li-sensor tsa Hall.
1. Linear Hall sensor e na le Hall element, linear amplifier le emitter follower, le outputs analog quantity.
2. Sensor ea Holo ea mofuta oa switjha e entsoe ka motlakase oa motlakase, karolo ea Hall, amplifier e fapaneng, trigger ea Schmitt le sethala sa tlhahiso, 'me e hlahisa bongata ba digital.
Lintho tse entsoeng ka lisebelisoa tsa semiconductor tse thehiloeng ho phello ea Holo li bitsoa likarolo tsa Hall. E na le melemo ea ho ba le maikutlo a matla a matla a khoheli, e bonolo ka sebopeho, e nyane ka boholo, karabelo e pharaletseng ea maqhubu, phapano e kholo ea phallo ea motlakase le nako e telele ea bophelo ba ts'ebeletso. Ka hona, e 'nile ea sebelisoa haholo masimong a ho lekanya, ho iketsetsa, k'homphieutha le theknoloji ea tlhahisoleseding.
Mka kopo
Li-sensor tsa phello ea holo li sebelisoa haholo e le li-sensors tsa boemo, tekanyo ea lebelo la ho potoloha, li-switches tsa moeli le tekanyo ea phallo. Lisebelisoa tse ling li sebetsa ho ipapisitse le phello ea Holo, joalo ka lisensor tsa hona joale tsa Hall effect, li-switches tsa makhasi a Hall effect, le li-sensor tsa matla a matla a matla a Hall effect. Ka mor'a moo, sensor ea boemo, sensor ea lebelo la ho potoloha le mocheso kapa sensor ea khatello li hlalosoa haholo-holo.
1. Sensor ea boemo
Li-sensor tsa phello ea holo li sebelisetsoa ho utloa ho sisinyeha ho thellang, mofuteng ona oa sensor ho tla ba le lekhalo le laoloang ka thata lipakeng tsa karolo ea holo le makenete, 'me matla a khoheli a tla fetoha ha makenete e ntse e ea pele le morao ka lekhalo le tsitsitseng. Ha element e le haufi le palo e ka leboea, tšimo e tla ba mpe, 'me ha element e le haufi le poleiti e ka boroa, matla a khoheli a tla ba a nepahetseng. Li-sensor tsena li boetse li bitsoa "proximity sensors" mme li sebelisetsoa ho beha maemo hantle.
2. Sensor ea lebelo
Ha u utloa lebelo, sensor ea Hall effect e behiloe hantle e shebane le makenete e potolohang. makenete ona o potolohang o hlahisa matla a khoheli a hlokahalang ho sebelisa sensor kapa karolo ea Hall. Tlhophiso ea limakete tse potolohang li ka fapana, ho ipapisitse le boiketlo ba ts'ebeliso. Tse ling tsa litokisetso tsena ke ka ho kenya makenete e le 'ngoe holim'a shaft kapa hub kapa ka ho sebelisa makenete a reng. Sensor ea Hall e fana ka pulse nako le nako ha e shebane le makenete. Ntle le moo, li-pulse tsena li laoloa ke processor ho tseba le ho bonts'a lebelo ho RPM. Li-sensor tsena e ka ba li-sensor tsa digital kapa linear analog output.
3. Mocheso kapa khatello ea maikutlo
Li-sensor tsa Hall effect li ka sebelisoa hape e le li-sensor tsa khatello le mocheso, li-sensor tsena li kopantsoe le diaphragm e khelosang khatello e nang le limatlase tse loketseng, 'me kopano ea mabone ea melumo e tsamaisa karolo ea Hall ho ea pele le pele.
Tabeng ea tekanyo ea khatello, melumo e ka atolosoa le ho honyela. Liphetoho tsa moutloa li etsa hore kopano ea makenete e atamele haufi le karolo ea Hall effect. Ka hona, motlakase o hlahisoang o hlahisoa o lekana le khatello e sebelisitsoeng.
Tabeng ea litekanyo tsa mocheso, kopano ea li-bellows e tiisitsoe ka khase e nang le litšobotsi tse tsebahalang tsa ho atolosa mocheso. Ha kamore e futhumetse, khase e ka hare ho moutloa ea atoloha, e leng se etsang hore sensor e hlahise motlakase o lekanang le mocheso.
