Ezweni elithuthuka ngokushesha lokukhiqizwa kwezimboni, ukuba yisicaba kwezindawo zomkhiqizo kuyisibonakaliso esibalulekile sekhwalithi yomkhiqizo. Ukutholwa kokuba yisicaba kusetshenziswa kabanzi kuzo zonke izimboni ezahlukene, njengokukhiqiza izimoto, izindiza, kanye ne-elekthronikhi. Izibonelo zifaka phakathi ukuhlolwa kokuba yisicaba kwamabhethri noma izindlu zefoni ephathekayo embonini yezimoto, kanye nokuhlolwa kokuba yisicaba kwamaphaneli e-LCD embonini ye-semiconductor.
Kodwa-ke, izindlela zokuthola ukuthamba kwendabuko zihlushwa izinkinga ezifana nokusebenza kahle okuphansi kanye nokunemba okungekuhle. Ngokuphambene nalokho, izinzwa ze-LVDT (Linear Variable Differential Transformer), ngezinzuzo zazo zokunemba okuphezulu, ukuthembeka okuphezulu, kanye nokulinganisa okungenamshuzo (isibonelo: Ama-LVDT asebenzisa i-probe ukuze axhumane nobuso bento, eqhuba ukufuduka kwe-core ukuze kufezwe ukulinganisa okungenamshuzo kanye nokunemba okuphezulu), manje sezisetshenziswa kabanzi ekutholeni ukuthamba kwento kwesimanje.
Isimiso Sokusebenza:
Ukulinganisa Okungashayisani:Ngokuvamile akukho ukuthintana ngokomzimba phakathi kwe-core ehambayo nesakhiwo sekhoyili, okusho ukuthi i-LVDT iyithuluzi elingenakho ukungqubuzana. Lokhu kuvumela ukusetshenziswa kwayo ezilinganisweni ezibalulekile ezingakwazi ukubekezelela ukungqubuzana.
Impilo Yomshini EngenamkhawuloNgenxa yokuthi ngokuvamile akukho ukuxhumana phakathi kwesakhiwo se-LVDT kanye nesakhiwo sekhoyili, azikho izingxenye ezingaguga noma ziguge, okunikeza ama-LVDT impilo yemishini engenamkhawulo. Lokhu kubaluleke kakhulu ezisetshenzisweni ezinokwethenjelwa okuphezulu.
Isixazululo EsingenamkhawuloAma-LVDT angalinganisa izinguquko ezincane kakhulu endaweni eyinhloko ngoba asebenza ngezimiso zokuxhumanisa nge-electromagnetic esakhiweni esingenakho ukungqubuzana. Okuwukuphela komkhawulo ekuxazululweni umsindo ku-conditioner yesignali kanye nesisombululo sesibonisi sokukhipha.
Ukuphindaphinda kwe-Null Point:Indawo yephuzu elingenalutho elingaphakathi le-LVDT lizinzile kakhulu futhi liyaphindaphindeka, ngisho nangaphezu kobubanzi bayo obukhulu bokushisa bokusebenza. Lokhu kwenza ama-LVDT asebenze kahle njengezinzwa zesikhundla esingenalutho ezinhlelweni zokulawula ezivaliwe.
Ukwenqatshwa kwe-Cross-Axis:Ama-LVDT azwela kakhulu ekunyakazeni kwe-axial kwe-core futhi awazweli kakhulu ekunyakazeni kwe-radial. Lokhu kuvumela ama-LVDT ukuthi asetshenziswe ukukala ama-core angahambi emgqeni oqondile.
Impendulo Esheshayo Eguquguqukayo:Ukungabikho kokungqubuzana ngesikhathi sokusebenza okuvamile kuvumela i-LVDT ukuthi iphendule ngokushesha kakhulu ezinguqukweni zesikhundla esiyinhloko. Impendulo eguquguqukayo yenzwa ye-LVDT ngokwayo inqunyelwe kuphela yimiphumela ye-inertial yesisindo esincane senhloko.
Umphumela Ophelele:Ukukhishwa kwe-LVDT kuyisignali ye-analog ehlobene ngqo nendawo. Uma kwenzeka ukucima kukagesi, ukulinganisa kungaqalwa kabusha ngaphandle kokulungiswa kabusha (ugesi udinga ukuvulwa ukuze kutholakale inani lokufuduka kwamanje ngemva kokucima kukagesi).
- Ukutholwa Kokuthamba Komphezulu Wezinto Zokusebenza: Ngokuthinta ubuso bento yokusebenza nge-probe ye-LVDT, ukushintshashintsha kokuphakama ebusweni kungalinganiswa, ngaleyo ndlela kuhlolwe ukuthi buyisicaba kangakanani.
- Ukutholwa Kokuthamba Kwensimbi Yeshidi: Ngesikhathi sokukhiqizwa kwensimbi eshidi, ukwakheka kwe-LVDT okuhleliwe, kuhlanganiswe nendlela yokuskena ezenzakalelayo, kungafeza imephu yokusicaba egcwele indawo yamaphepha amakhulu.
- Ukutholwa Kokuthamba Kwesikwele:Embonini ye-semiconductor, ukuba yisicaba kwama-wafer kunomthelela omkhulu ekusebenzeni kwama-chip. Ama-LVDT angasetshenziswa ukukala ngokunembile ukuba yisicaba kwezindawo ze-wafer. (Qaphela: Ekutholakaleni kokuba yisicaba kwama-wafer, i-LVDT idinga ukuhlonyiswa ngama-probe alula kanye nomklamo wamandla okuxhumana aphansi, okwenza ifanelekele izimo lapho umonakalo ebusweni ungavunyelwe khona.)
- Ukuphindaphinda kwezinga le-Micrometer
- Izinhlobo eziningi ziyatholakala kusukela ku-5-20mm
- Izinketho zokukhipha eziphelele, kufaka phakathi isignali yedijithali, i-analog, kanye ne-485.
- Ingcindezi yekhanda ephansi njenge-3N sensing pressure, ekwazi ukubona okungagugi kuzo zombili izindawo zengilazi zensimbi.
- Ubukhulu obucebile bangaphandle ukuze kuhlangatshezwane nezikhala ezahlukene zesicelo.
