Muuqaalka si xawli ah u socda ee wax soo saarka warshadaha, fidsanaanta dusha sare ee badeecaddu waa tilmaame muhiim ah oo ku saabsan tayada badeecada. Ogaanshaha fidsanaanta waxaa si weyn loogu isticmaalaa warshado kala duwan, sida wax soo saarka baabuurta, hawada sare, iyo elektarooniga. Tusaalooyinka waxaa ka mid ah kormeerka fidsanaanta baytariyada ama guryaha taleefannada gacanta ee warshadaha mootooyinka, iyo kormeerka fidsanaanta ee looxyada LCD ee warshadaha semiconductor-ka.
Si kastaba ha ahaatee, hababka ogaanshaha fidsan ee dhaqameed waxay la ildaran yihiin arrimo ay ka mid yihiin hufnaan hoose iyo saxnaan liidata. Taas bedelkeeda, dareemayaasha LVDT (Linear Variable Variable Differential Transformer), oo leh faa'iidooyinkooda saxnaanta sare, isku halaynta sare, iyo cabbir aan is jiidjiid lahayn (tusaale ahaan: LVDTs waxay isticmaalaan baaritaan si ay ula xiriiraan dusha sare ee shayga, iyagoo horseedaya barokaca asaasiga ah si loo gaaro cabbir aan is jiidjiid lahayn iyo saxnaan sare), hadda si weyn ayaa loogu isticmaalaa ogaanshaha fidsan ee shayga casriga ah.
Mabda'a Hawlgalka:
Cabbiraad aan kala go 'lahayn:Caadiyan ma jiro xiriir jireed oo u dhexeeya xudunta dhaqdhaqaaqa iyo qaab-dhismeedka gariiradda, taasoo la macno ah in LVDT uu yahay aalad aan is jiidjiid lahayn. Tani waxay u oggolaanaysaa isticmaalkeeda cabbiraadaha muhiimka ah ee aan u dulqaadan karin rarista is jiidjiidka.
Nolosha Farsamada ee aan Xaddidanayn: Maadaama aysan caadiyan jirin wax xiriir ah oo u dhexeeya qaab-dhismeedka xudunta iyo gariiradda LVDT, ma jiraan qaybo isku xoqi kara ama duugoobaya, taasoo siinaysa LVDT-yada nolol farsamo oo aan xadidnayn. Tani waxay si gaar ah muhiim ugu tahay codsiyada kalsoonida sare leh.
Xallinta aan dhammaadka lahaynLVDT-yadu waxay cabbiri karaan isbeddello yaryar oo aan dhammaad lahayn oo ku yimaada booska asaasiga ah sababtoo ah waxay ku shaqeeyaan mabaadi'da isku xidhka elektromagnetic-ka ee qaab-dhismeed aan lahayn is-khilaaf. Xaddidaadda kaliya ee xallinta waa buuqa ku jira qaboojiyaha calaamadda iyo xallinta bandhigga wax soo saarka.
Ku celcelinta Barta Null:Goobta barta null-ka ee gudaha ee LVDT waa mid aad u deggan oo la soo celin karo, xitaa marka loo eego heerkulka hawlgalka oo aad u ballaaran. Tani waxay ka dhigaysaa LVDT-yadu inay si fiican u shaqeeyaan sida dareemayaasha booska null ee nidaamyada xakamaynta ee loo yaqaan 'closed-loop'.
Diidmada Dhinacyada Isdhaafsiga ah:LVDT-yadu aad bay ugu nugul yihiin dhaqdhaqaaqa axial-ka ee xudunta waxayna u nugul yihiin dhaqdhaqaaqa radial-ka. Tani waxay u oggolaanaysaa LVDT-yada in loo isticmaalo cabbiraadda xudunta aan ku socon xariiq toosan oo sax ah.
Jawaab Dhaqso leh oo Firfircoon:Maqnaanshaha is jiidjiidashada inta lagu jiro hawlgalka caadiga ah waxay u ogolaanaysaa LVDT inuu si dhakhso ah uga jawaabo isbeddellada booska asaasiga ah. Jawaabta firfircoon ee dareemaha LVDT laftiisu waxay ku xaddidan tahay oo keliya saameynta aan la taaban karin ee cufnaanta yar ee xudunta.
Wax soo saar dhammaystiran:Wax soo saarka LVDT waa calaamad analog ah oo si toos ah ula xiriirta booska. Haddii koronto go'an dhacdo, cabbiraadda dib ayaa loo bilaabi karaa iyada oo aan dib loo habeyn (korontada waa in dib loo shidaa si loo helo qiimaha barokaca hadda jira ka dib marka korontada go'do).
- Ogaanshaha Fidsanaanta Dusha Sare ee Workpiece: Marka la taabto dusha sare ee shaqada iyadoo la adeegsanayo baaritaanka LVDT, kala duwanaanshaha dhererka ee dusha sare ayaa la cabbiri karaa, taasoo lagu qiimeynayo fidsanaantiisa.
- Ogaanshaha Fidsan ee Birta SheetInta lagu jiro wax soo saarka birta xaashida ah, qaab-dhismeedka LVDT ee la kala soocay, oo ay weheliso farsamo sawir-qaadis otomaatig ah, ayaa gaari kara khariidaynta dusha sare oo buuxda oo ah xaashiyo waaweyn.
- Ogaanshaha Fidsanaanta Wafer:Warshadaha semiconductor-ka, fidsanaanta wafer-ku waxay saameyn weyn ku leedahay waxqabadka jajabka. LVDT-yada waxaa loo isticmaali karaa in si sax ah loo cabbiro fidsanaanta dusha sare ee wafer-ka. (Fiiro gaar ah: Marka la ogaanayo fidsanaanta wafer-ka, LVDT-gu wuxuu u baahan yahay in lagu qalabeeyo baaritaanno fudud iyo naqshad xoog xiriir hoose leh, taasoo ka dhigaysa mid ku habboon xaaladaha aan loo oggolaan in waxyeello loo geysto dusha sare.)
