1. Ukuphila Okukhawulelwe:Izinzwa ze-Galvanic zinesikhathi sokuphila esilinganiselwe, ngokuvamile esisukela ezinyangeni ezimbalwa kuya eminyakeni embalwa, kuye ngohlelo lokusebenza.Kumelwe zishintshwe lapho ubude bazo bokuphila bufinyelelwa.
2. Ukusetshenziswa Komoya-mpilo:Lezi zinzwa zisebenzisa umoya-mpilo phakathi kwenqubo yokulinganisa, okungase kuthinte indawo yesampula futhi kungase kungafaneli izinhlelo zokusebenza lapho kudingeka khona ukuphazamiseka okuncane.
3. Ukuphazamiseka Okuvela Kwamanye Ama-Ions:Izinzwa ze-galvanic ziyazwela ekuphazanyisweni kwamanye ama-ion emanzini, okungase kuholele ekufundweni okunganembile.
I-Optical Dissolved Oxygen Sensors: Galvanic vs Optical Dissolved Oxygen Sensors
A. Okuyisisekelo Kwezinzwa Zokubona:
I-Optical Dissolved Oxygen Sensors, ngakolunye uhlangothi, ithatha indlela ehluke kakhulu yokulinganisa ukugcwala komoyampilo.Lezi zinzwa zisebenzisa odayi be-luminescent abashumekwe kusici senzwa.Uma lesi sakhi sihlangana nomoya-mpilo, sibangela ukusabela kwe-luminescent.
B. Indlela Esebenza Ngayo:
Udayi we-luminescent ukhipha ukukhanya uma ujatshuliswa umthombo wokukhanya wangaphandle.Umoya-mpilo ucisha le luminescence, futhi izinga lokucisha lihlobene ngokuqondile nokuhlushwa komoya-mpilo oncibilikisiwe.Inzwa ithola izinguquko ku-luminescence bese ibala amazinga komoyampilo ancibilikisiwe ngokufanele.
C. Izinzuzo Zezinzwa Zomoya Eziyi-Optical Dissolved Oxygen:
1. Ubude bempilo:Izinzwa ze-Optical ziphila isikhathi eside uma ziqhathaniswa nezinzwa ze-galvanic.Zingahlala iminyaka eminingana ngaphandle kokudinga ukushintshwa njalo.
2. Akukho Ukusetshenziswa Kwe-Oxygen:Izinzwa zamehlo aziwudli umoya-mpilo ngesikhathi sokulinganisa, okuzenza zilungele izinhlelo zokusebenza lapho ukuphazamiseka okuncane kwendawo yesampula kubalulekile.
3. Ukuphazamisa Okuncane:Izinzwa zamehlo azikwazi ukuphazanyiswa kancane kwamanye ama-ion emanzini, okuholela ekufundeni okunembe kakhudlwana nokuzinzile.
D. Ububi be-Optical Dissolved Oxygen Sensors:
1. Isikhathi Sokuphendula Esinensayo:Izinzwa zamehlo ngokuvamile zinesikhathi sokuphendula esinensa uma kuqhathaniswa nezinzwa ze-galvanic.Angase angalungeli izinhlelo zokusebenza lapho idatha yesikhathi sangempela ibalulekile.
2. Izindleko Zokuqala Eziphakeme:Ukutshalwa kwezimali kokuqala kwezinzwa zokubona ngokuvamile kuphezulu kunaleyo yezinzwa ze-galvanic.Nokho, ukuphila okude kungase kuqede lezi zindleko ngokuhamba kwesikhathi.
3. Kuyazwela ekungcoleni:Izinzwa zamehlo zingaba lula ekungcoleni, okungase kudinge ukuhlanzwa nokunakekelwa ngezikhathi ezithile, ikakhulukazi ezinhlelweni ezisetshenziswayo ezinamazinga aphezulu ezinto eziphilayo noma i-biofouling.
