Ungayikhetha Kanjani Imitha Yokugeleza Kagesi Efanele?

Uma ukhethaimitha yokugeleza kagesi(EMF), izici eziningana ezibalulekile kumele zicatshangelwe ukuqinisekisa izilinganiso ezinembile kanye nokuthembeka kwesikhathi eside:

1. Izidingo Eziphakathi
   Uketshezi kumele luhambisane (ngokuvamile ≥5 μS/cm), njengokuthi:

• Amanzi (amanzi ompompi, indle, amanzi olwandle)
• Izixazululo ze-asidi ne-alkaline (imboni yamakhemikhali)
• Udaka, uginindela, kanye nodaka lwamaminerali (izingxube eziqinile-uketshezi ezihambisa umoya)

Akufanelekile kuma-fluid angahambisani nogesi, njenge:

1. • Amanzi ahlanzekile, amanzi acwengekile
   • Amafutha (i-petroleum, i-petroleum, i-diesel)
   • Izithako ezithile eziphilayo (isb. utshwala, i-benzene)
2. Ububanzi bepayipi kanye nezinga lokugeleza
   Khetha imitha yokugeleza ehambisana nobubanzi bokugeleza obufanele. Ngokuvamile, kunconywa ijubane lokugeleza elingu-1–5 m/s. Ijubane lokugeleza eliphansi kakhulu lingathinta ukunemba kokulinganisa, kanti ukuphakama kakhulu kungandisa ukulahlekelwa yingcindezi.
   Ububanzi bepayipi kufanele bufane nosayizi wemitha yokugeleza. Uma ijubane lokugeleza liphansi kakhulu, khetha ububanzi obuncane ukuze uthuthukise ukuzinza kokulinganisa.
3. Ukukhethwa Kwezinto Zokufaka Ama-electrode kanye Nezindwangu
   Izinto zokwakha ama-electrode kanye nolwelwesi kufanele zikhethwe ngokusekelwe ekuboleni, izinga lokushisa, kanye nezimo zokuguguleka koketshezi:

   Izinto	Okuphakathi Okufanelekile
   Izinto ze-Electrode
   Insimbi Engagqwali engu-316L	Indle, uketshezi olungathathi hlangothi
   I-Tantalum (Ta)	Ama-asidi aqinile (isb., i-nitric acid, i-sulfuric acid)
   Iplatinum (Pt)	Uketshezi oluqothulayo kakhulu nolushisa kakhulu
   I-Titanium (i-Ti)	Amanzi olwandle, uketshezi oluqukethe i-chloride
   Izinto Zokufaka Ulwelwesi
   Irabha	Amanzi ajwayelekile, indle, udaka
   I-PTFE (i-Teflon)	Ama-asidi aqinile, ama-alkali aqinile
   I-Neoprene	Uketshezi olunezinhlayiya, ama-slurry amaminerali

4. Imibandela Yokufaka
   • Ubude Bepayipi Eliqondile: Ubude obunconywayo ngaphambi kwemitha yokugeleza buphindwe izikhathi ezingu-≥5 kunobubanzi bepayipi kanye nezikhathi ezingu-≥2 ngemva kwemitha ukuze kugwenywe ukuphazamiseka kwezimo zokugeleza.
   • Ukugeleza Kwepayipi Okugcwele: Imitha yokugeleza kufanele ifakwe engxenyeni yepayipi egcwele ukuvimbela amabhamuza omoya namapayipi angenalutho ukuthi angaphazamisi ukunemba kokulinganisa.
   • Izici Zemvelo: Gwema ukuphazamiseka okukhulu kwe-electromagnetic okuvela emithonjeni efana nama-variable frequency drive noma ama-motor; ukusekelwa okufanele kubalulekile.
5. Iphrothokholi Yesignali Yokuphuma Nokuxhumana
   • Izimpawu ze-Analog: 4-20mA (isignali evamile yezimboni)
   • Ukuxhumana Kwedijithali: RS485 (Modbus), HART, Profibus
   • Umphumela we-Pulse: Kufanelekela izinhlelo zokusebenza zokulinganisa
6. Ukunikezwa kwamandla kagesi
   • I-AC 220V/110V (yokufakwa okuhleliwe)
   • I-DC 24V (yezinhlelo zokwenza izinto ngokuzenzakalela zezimboni)
   • Isebenza ngebhethri (ezindaweni ezikude ezingenawo amandla angaphandle)
7. Ezinye Izidingo Ezikhethekile
   • Ukulinganisa Okuqondiswa KabiliUma kudingeka ukulinganisa ukugeleza okuphambene, khetha imodeli esekela ukulinganisa okuqondiswayo.
   • Isilinganiso Sokuvikela: IP65 (izindawo ezijwayelekile), IP67/IP68 (izindawo zangaphandle noma ezingaphansi kwamanzi).
   • Izidingo Ezingaqhumi: Ukuze kusetshenziswe ezindaweni ezisebenzisa uphethiloli noma eziyingozi, kufanele kukhethwe imitha yokugeleza engaqhumi.

Ukucabangela lezi zici kuzokusiza ukuthi ukhethe imitha yokugeleza kagesi efanele isicelo sakho.
