Isahluli sesinyithi sisixhobo sombane esisebenzisa umgaqo wokungeniswa kwe-electromagnetic ukukhangela isinyithi. Inokwahlulwa ibe yintlobo yetshaneli, uhlobo oluwayo, kunye nodidi lombhobho.
Umgaqo wesahluli sesinyithi:
Isahluli sesinyithi sisebenzisa umgaqo wokungeniswa kwe-electromagnetic ukubona iintsimbi. Zonke iintsimbi, kubandakanywa intsimbi kunye neentsimbi ezingenayo i-ferrous, zinovakalelo oluphezulu lokubona. Xa isinyithi singena kwindawo yokufumanisa, iya kuchaphazela ukuhanjiswa kwemigca yamagnetic kwindawo yokufumanisa, ngaloo ndlela ichaphazela i-magnetic flux ngaphakathi koluhlu olusisigxina. Iintsimbi ezingezizo i-ferromagnetic ezingena kwindawo yokubhaqa ziya kuvelisa iziphumo zangoku ze-eddy kwaye zibangele utshintsho kumhlaba wosasazo wemagnethi kwindawo yobhaqo. Ngokuqhelekileyo, i-separator yensimbi iqulethe iinxalenye ezimbini, ezizezi zesahluli zentsimbi kunye nesixhobo sokususa ngokuzenzekelayo, kunye ne-detector njengenxalenye engundoqo. Kukho iiseti ezintathu zeekhoyili ezisasazwe ngaphakathi kwesixhobo, ezizezi, icoil yokuhambisa esembindini kunye neekhoyili ezimbini ezilinganayo zokufumana. I-high-frequency variable magnetic field yenziwa yi-oscillator exhunywe kwi-coil yokudlulisa phakathi. Kwimeko engasebenziyo, i-voltages enyanzelwayo yeekhoyili ezimbini ezifumana iikhoyili ziyacima enye nenye ngaphambi kokuba imagnethi iphazamiseke, ifikelele kwimo elinganayo. Emva kokuba ukungcola kwetsimbi kungene kwindawo yamagnetic kwaye intsimi yamagnetic iphazamisekile, le bhalansi iphukile, kwaye i-voltage edibeneyo yeekhoyili ezimbini ezifumanayo ayinakucinywa. I-voltage engakhanselwanga i-induced ikhuliswa kwaye iqhutywe yinkqubo yokulawula, kwaye isibonakaliso se-alarm senziwa (ukungcola kwetsimbi kufunyenwe). Inkqubo inokusebenzisa lo mqondiso we-alarm ukuqhuba izixhobo zokususa ngokuzenzekelayo, njl., Ukususa ukungcola kwetsimbi kumgca wokufakela.
Iingenelo zokusebenzisa isahluli sesinyithi:
1. Khusela izixhobo zokufakela
2. Ukuphucula ukusebenza kakuhle kofakelo
3. Ukuphucula izinga lokusetyenziswa kwemathiriyeli ekrwada
4. Ukuphucula umgangatho wemveliso
5. Ukunciphisa iindleko zokugcinwa kwezixhobo kunye nelahleko ebangelwa kukulungiswa kwexesha lokuphumla
