Kwindawo ekhula ngokukhawuleza yemveliso yemizi-mveliso, ukuba tyaba komphezulu wemveliso luphawu olubalulekileyo lomgangatho wemveliso. Ukufunyanwa kokuba tyaba kusetyenziswa kakhulu kumashishini ahlukeneyo, njengokwenziwa kweemoto, i-aerospace, kunye ne-elektroniki. Imizekelo ibandakanya ukuhlolwa kokuba tyaba kweebhetri okanye izindlu zeefowuni eziphathwayo kushishino lweemoto, kunye nokuhlolwa kokuba tyaba kweephaneli ze-LCD kushishino lwee-semiconductor.
Nangona kunjalo, iindlela zemveli zokufumanisa ukuba tyaba zineengxaki ezifana nokusebenza okuphantsi kunye nokuchaneka okungekho ngqiqweni. Ngokwahlukileyo koko, ii-sensors ze-LVDT (Linear Variable Differential Transformer), ezineenzuzo zokuchaneka okuphezulu, ukuthembeka okuphezulu, kunye nokulinganisa ngaphandle kokungqubana (umzekelo: ii-LVDT zisebenzisa i-probe ukuze ziqhagamshelane nomphezulu wento, ziqhuba ukufuduka kwe-core ukuze kufezekiswe ukulinganisa ngaphandle kokungqubana kunye nokuchaneka okuphezulu), ngoku zisetyenziswa kakhulu ekuchongeni ukuba tyaba kwezinto namhlanje.
Umgaqo-nkqubo Wokusebenza:
Umlinganiselo Ongenazingxabano:Ngokwesiqhelo akukho kudibana ngokomzimba phakathi kwesiseko esishukumayo kunye nesakhiwo sekhoyili, oko kuthetha ukuba i-LVDT sisixhobo esingenako ukungqubana. Oku kuvumela ukusetyenziswa kwayo kwiimilinganiselo ezibalulekileyo ezingakwaziyo ukunyamezela ukungqubana.
Ubomi boomatshini obungenamkhawulo: Ngenxa yokuba ngokuqhelekileyo akukho nxibelelwano phakathi kwesakhiwo se-LVDT kunye nesakhiwo se-coil, akukho malungu anokukhuhlana okanye aguge, nto leyo enika ii-LVDT ubomi boomatshini obungenamda. Oku kubaluleke kakhulu kwizicelo ezinokuthembeka okuphezulu.
Isisombululo Esingenasiphelo: Ii-LVDT zinokulinganisa utshintsho oluncinci olungenamkhawulo kwindawo ephambili kuba zisebenza kwimigaqo yokudibanisa i-electromagnetic kwisakhiwo esingenazo iingxabano. Umda kuphela kwisisombululo yingxolo kwi-signal conditioner kunye nesisombululo sesiboniso sesiphumo.
Ukuphinda-phinda kweNoll Point:Indawo ye-null point ye-LVDT izinzile kakhulu kwaye iyakwazi ukuphindwa, nokuba ikwiqondo lobushushu elibanzi kakhulu lokusebenza. Oku kwenza ii-LVDT zisebenze kakuhle njengezinzwa ze-null position kwiinkqubo zolawulo ezivaliweyo.
Ukungavunyelwa kweCross-Axis:Ii-LVDT zinovakalelo olukhulu kwintshukumo ye-axial ye-core kwaye azinamvakalelo kangako kwintshukumo ye-radial. Oku kuvumela ii-LVDT ukuba zisetyenziswe ukulinganisa ii-cores ezingashukumiyo kumgca othe tye ochanekileyo.
Impendulo Ekhawulezayo Eguqukayo:Ukungabikho kokungqubana ngexesha lokusebenza okuqhelekileyo kuvumela i-LVDT ukuba iphendule ngokukhawuleza kakhulu kutshintsho olukwindawo ephambili. Impendulo eguqukayo ye-sensor ye-LVDT ngokwayo inqunyelwe kuphela yimiphumo ye-inertial yobunzima obuncinci be-core.
Isiphumo esipheleleyo:Isiphumo se-LVDT sisignali ye-analog enxulumene ngqo nendawo. Ukuba umbane ucinyiwe, umlinganiselo ungaqalwa kwakhona ngaphandle kokulungiswa kwakhona (umbane kufuneka uvulwe ukuze ufumane ixabiso lokufuduka kwangoku emva kokucima umbane).
- Ukufunyanwa koBume boMphezulu weWorkpiece Flatness: Ngokuchukumisa umphezulu wesixhobo somsebenzi nge-LVDT probe, utshintsho lokuphakama kumphezulu lungalinganiswa, ngaloo ndlela kuvavanywa ukuba sithe tyaba kangakanani.
- Ukufunyanwa kweSheet Metal Flatness: Ngexesha lokuveliswa kwesinyithi, uyilo lwe-LVDT oludibeneyo, oludityaniswe nendlela yokuskena ezenzekelayo, lunokufezekisa imephu epheleleyo yokusithambeka kwamaphepha amakhulu.
- Ukufunyanwa kwe-Wafer Flatness:Kwishishini le-semiconductor, ukuba tyaba kwee-wafers kunempembelelo enkulu ekusebenzeni kwee-chip. Ii-LVDTs zingasetyenziselwa ukulinganisa ngokuchanekileyo ukuba tyaba kweendawo ze-wafers. (Qaphela: Ekufumaneni ukuba tyaba kwe-wafers ...
