Izinzwa zehholo zisekelwe kumphumela weHholo. Umphumela weHholo uyindlela eyisisekelo yokufunda izakhiwo zezinto zokwakha ze-semiconductor. I-coefficient yehholo elinganiswa ngokuhlolwa komthelela weHholo inganquma amapharamitha abalulekile afana nohlobo lwe-conductivity, ukugxilisa kwenkampani yenethiwekhi nokuhamba kwenkampani yenethiwekhi yezinto ezisetshenziswayo kwi-semiconductor.
Ukwahlukanisa
Izinzwa zehholo zihlukaniswe izinzwa zeHholo eziwumugqa kanye nezinzwa zeHholo ezishintshayo.
1. Inzwa yeHholo Lomugqa iqukethe isici seHholo, isikhulisi somugqa kanye nesilandeli se-emitter, kanye nenani le-analog yemiphumela.
2. Inzwa yeHholo yohlobo lokushintshwa yakhiwe ngesilawuli sikagesi, into yaseHholo, iamplifier ehlukile, i-Schmitt trigger nesiteji sokukhiphayo, futhi ikhipha amanani edijithali.
Izinto ezenziwe ngezinto ze-semiconductor ezisekelwe kumphumela weHholo zibizwa ngokuthi izakhi zeHholo. Inezinzuzo zokuzwela izizinda kazibuthe, ilula ngesakhiwo, incane ngosayizi, ibanzi ngokuphendula imvamisa, ukuhluka okukhulu kokuphumayo kanye nempilo ende yesevisi. Ngakho-ke, isetshenziswe kabanzi emikhakheni yokulinganisa, i-automation, ikhompyutha kanye nobuchwepheshe bolwazi.
Main application
Izinzwa zomphumela wehholo zisetshenziswa kabanzi njengezinzwa zokuma, ukulinganisa isivinini esijikelezayo, ukushintsha komkhawulo kanye nesilinganiso sokugeleza. Amanye amadivayisi asebenza ngokususelwe kumphumela weHholo, njengezinzwa zamanje ze-Hall effect, amaswishi eqabunga lomphumela weHholo, nezinzwa zamandla kazibuthe we-Hall effect. Okulandelayo, inzwa yokuma, inzwa yesivinini esijikelezayo kanye nezinzwa zokushisa noma zokucindezela kuchazwa kakhulu.
1. Inzwa yokuma
Izinzwa zomphumela wehholo zisetshenziselwa ukuzwa ukunyakaza okuslayidayo, kulolu hlobo lwenzwa kuzoba negebe elilawulwa ngokuqinile phakathi kwento yehholo nomazibuthe, futhi indawo kazibuthe ebangelwe izoshintsha njengoba uzibuthe uya emuva naphambili esikhaleni esingashintshi. Uma i-elementi iseduze nesigxobo sasenyakatho, inkambu izoba inegethivu, futhi lapho isici siseduze nesigxobo esiseningizimu, inkambu kazibuthe izoba iphozithivu. Lezi zinzwa zibizwa nangokuthi izinzwa eziseduze futhi zisetshenziselwa ukuma okunembile.
2. Inzwa yesivinini
Ekuzwakalini kwesivinini, inzwa yomphumela weHholo ibekwa iqonde ngqo kuzibuthe ezungezayo. Lo uzibuthe ozungezayo ukhiqiza inkambu kazibuthe edingekayo ukuze kusetshenziswe inzwa noma isici seHholo. Ukuhlelwa kozibuthe abazungezayo kungahluka, kuye ngokuthi isicelo sisebenziseka kalula. Amanye alawa malungiselelo angokufaka uzibuthe oyedwa kushafti noma ihabhu noma ngokusebenzisa ozibuthe abayindandatho. Inzwa yeHholo ikhipha i-pulse ephumayo njalo lapho ibhekene nomazibuthe. Ukwengeza, lawa ma-pulses alawulwa iphrosesa ukuze anqume futhi abonise isivinini ku-RPM. Lezi zinzwa zingaba izinzwa ze-analog zedijithali noma ezinomugqa.
3. Inzwa yokushisa noma yokucindezela
Izinzwa zomphumela wehholo nazo zingasetshenziswa njengezinzwa zokucindezela nezinga lokushisa, lezi zinzwa zihlanganiswa ne-diaphragm ehlanekezela ingcindezi enamazibuthe afanelekile, futhi ukuhlangana kokazibuthe kokuvuthela kushukumisa isici somphumela weHholo emuva naphambili.
Esimeni sokulinganisa ingcindezi, ama-bellows angaphansi kokunwetshwa nokufinyela. Izinguquko ekuvutheleni zibangela ukuhlangana kuzibuthe kusondele kusici somphumela weHholo. Ngakho-ke, umphumela we-voltage ophumayo ulingana nengcindezi esetshenzisiwe.
Esimeni sokukalwa kwezinga lokushisa, i-bellows assembly ivalwa ngegesi enezici ezaziwayo zokunwetshwa kokushisa. Lapho igumbi lishiswa, igesi engaphakathi kwesivunguvungu iyakhula, okwenza inzwa ikhiqize i-voltage elingana nezinga lokushisa.
