Imitha Yokuthuthumela E-inthanethi Indle Esetshenzisiwe

Isingeniso

I-transmitter ingasetshenziswa ukubonisa idatha elinganiswe yinzwa, ukuze umsebenzisi athole umphumela we-analog ongu-4-20mA ngokucushwa kwesixhumi esibonakalayo se-transmitter.

kanye nokulinganisa.Futhi kungenza ukulawula ukudluliselwa, ukuxhumana kwedijithali, kanye neminye imisebenzi kube ngokoqobo. Lo mkhiqizo usetshenziswa kabanzi esikhungweni sendle, emanzini

isitshalo, isiteshi samanzi, amanzi angaphezulu,ezolimo, izimboni kanye neminye imikhakha.

Kuyini i-Turbidity?

Ukuvuvukala, isilinganiso sokufiphala koketshezi, kuye kwaqashelwa njengesibonakaliso esilula nesiyisisekelo sekhwalithi yamanzi. Ibilokhu isetshenziselwa ukuqapha amanzi okuphuza, okuhlanganisa nalawo akhiqizwa ngokuhlunga amashumi eminyaka.UkuvuvukalaUkulinganisa kuhilela ukusetshenziswa kogongolo lokukhanya, olunezici ezichaziwe, ukunquma ukuba khona kwenani elincane lezinto ezisanhlamvu ezikhona emanzini noma kwenye isampula yoketshezi. Ugongolo lokukhanya lubizwa ngokuthi ugongolo lokukhanya oluzayo. Izinto ezikhona emanzini zibangela ukuba ugongolo lokukhanya oluzayo luhlakazeke futhi lokhu kukhanya okusakazekile kuyatholakala futhi kulinganiswe uma kuqhathaniswa nendinganiso yokulinganisa elandelekayo. Uma inani lezinto ezisanhlamvu eziqukethwe kusampula liphezulu, kulapho ukuhlakazeka kogongolo lokukhanya oluzayo kukhulu khona futhi kulapho ukungcola okubangelwayo kukhuphuka khona.

Noma iyiphi inhlayiya engaphakathi kwesampula edlula emthonjeni wokukhanya ochaziwe (ngokuvamile isibani se-incandescent, i-diode ekhipha ukukhanya (i-LED) noma i-laser diode), ingaba nomthelela ekungcoleni okuphelele kwesampula. Umgomo wokuhlunga ukususa izinhlayiya kunoma iyiphi isampula enikeziwe. Lapho izinhlelo zokuhlunga zisebenza kahle futhi ziqashwe nge-turbidimeter, ukungcola kokungcola kuzobonakala ngokulinganisa okuphansi nokuzinzile. Amanye ama-turbidimeter awasebenzi kahle emanzini ahlanzekile kakhulu, lapho ubukhulu bezinhlayiya kanye namazinga enombolo yezinhlayiya ephansi kakhulu. Kulawo ma-turbidimeter antula ukuzwela kula mazinga aphansi, izinguquko zokungcola ezibangelwa ukwephulwa kwesihlungi zingaba zincane kangangokuthi azihlukaniseki nomsindo oyisisekelo wokungcola wethuluzi.

Lo msindo oyisisekelo unemithombo eminingana ehlanganisa umsindo wezinsimbi ongokwemvelo (umsindo we-elekthronikhi), ukukhanya okulahlekile kwezinsimbi, umsindo wesampula, kanye nomsindo emthonjeni wokukhanya uqobo. Lokhu kuphazamiseka kuyanezela futhi kuba umthombo oyinhloko wezimpendulo zokungcoliswa okungamanga futhi kungathinta kabi umkhawulo wokutholwa kwezinsimbi.
