    hordhaca alaabta

    1. Isgaarsiinta fog

    Hadda (4 ilaa 20 mA) waa isku-xidhka analooga ee la door bidayo marka la gudbinayo macluumaadka meel fog. Tani waa sababta oo ah wax soo saarka danabku wuxuu aad ugu nugul yahay faragelinta buuqa, iyo calaamadda lafteeda waxaa lagu dhimi doonaa caabbinta fiilada. Si kastaba ha ahaatee, wax soo saarka hadda wuxuu u adkeysan karaa masaafo dheer wuxuuna bixiyaa akhrin cadaadis sax ah oo dhamaystiran oo ka yimaada gudbiyaha ilaa nidaamka helitaanka xogta.

     

    2. Adkeysiga faragelinta RF

    Xadhkaha fiilada ayaa u nugul faragelinta korantada (EMI)/ inta jeer ee raadiyaha (RFI)/Electrostatic (ESD) ee fiilooyinka iyo xadadka ku xiga. Dhawaaqan korantada ee aan loo baahnayn waxay dhaawac weyn u geysan doontaa ishaarooyinka sare u kaca sida calaamadaha korantada. Dhibaatadan si fudud ayaa looga gudbi karaa iyadoo la isticmaalo is-hortaag hoose iyo calaamado sare oo hadda jira, sida 4-20 mA.

     

    3, cilad bixinta

    Calaamadda 4-20mA waxay leedahay soo saarid 4mA ah qiimaha cadaadiskuna waa eber. Tani waxay asal ahaan ka dhigan tahay in calaamaduhu leeyahay "eber nool", markaa xitaa haddii akhriska cadaadiska eber yahay, waxay cuni doontaa 4 mA oo hadda ah. Haddii calaamaduhu u dhaco 0 mA, shaqadani waxay siin kartaa isticmaalaha calaamad cad oo ah qaladka akhriska ama luminta calaamadaha. Taas laguma gaadhi karo marka la eego calaamadaha danabka, kuwaas oo inta badan u dhexeeya 0-5 V ama 0-10 V, halkaas oo wax soo saarka 0 V uu muujinayo cadaadiska eber.

     

    4. Go'doominta isha

    4-20mA signalka soo saarida waa calaamad hoose oo hoosaysa, iyo dhulka labada daraf (gudbinta iyo helista) waxay u horseedi kartaa dhul-goosad, taasoo keenta calaamad aan sax ahayn. Si taas looga fogaado, xariiq kasta oo 4-20 mA ah waa in si sax ah loo go'doomiyo. Si kastaba ha noqotee, marka la barbar dhigo soosaarka 0-10 V, tani waxay ka hortagtaa dareemayaasha inuu noqdo silsilad-silsilad ah oo hal kaabayaasha fiilada ah.

     

    5. Helitaanka saxnaanta

    Markaad ka gudbinayso dareeraha cadaadiska, voltmeter-ku wuxuu si fudud u tarjumi karaa calaamadda 0-10 V ee dhamaadka helitaanka. Wax soo saarka 4-20 mA, calaamadda waxaa la akhriyi karaa oo keliya ka dib marka soo-dhoweeyaha loo beddelo danab. Si signalkan loogu badalo hoos u dhac danab ah, resistor waxa uu si xidhiidh ah ugu xidhan yahay meesha wax soo saarka. Saxnaanta iska caabiyahani aad bay muhiim ugu tahay saxnaanta cabbirka calaamadda la helay.
