Umphumela Wenzwa Yokujika Kwezimboni 4-20mA

Isingeniso

Izinzwa zokungcola eziku-inthanethiukuze kulinganiswe ukukhanya okuhlakazekile okulenga ezingeni lezinto ezingabonakali zoketshezi ezinganyibiliki ezikhiqizwe yi-umzimba futhi ungakwazilinganisa amazinga ezinhlayiya ezilengayo. Ingasetshenziswa kabanzi ekulinganisweni kokungcola okuku-inthanethi, esiteshini sikagesi, ezitsheni zamanzi ahlanzekile,izitshalo zokuhlanza indle,izitshalo zeziphuzo, iminyango yokuvikela imvelo, amanzi ezimboni, imboni yewayini kanye nemboni yezemithi, ubhubhaneiminyango yokuvimbela,izibhedlela kanye neminye iminyango.

Izici

1. Hlola futhi uhlanze ifasitela njalo ngenyanga, ngebhulashi lokuhlanza elizenzakalelayo, bhulasha isigamu sehora.

2. Sebenzisa ingilazi yesafire ukuze uyigcine icocekile kalula, uma uhlanza sebenzisa ingilazi yesafire engaklwebhi, ungakhathazeki ngobuso befasitela obugugile.

3. Indawo yokufaka encane, hhayi eyinkimbinkimbi, ifakiwe nje ukuze iqedele ukufakwa.

4. Ukulinganisa okuqhubekayo kungafinyelelwa, umkhiqizo we-analog ongu-4~20mA owakhelwe ngaphakathi, ungadlulisela idatha emshinini ohlukahlukene kuye ngesidingo.

5. Ububanzi bokulinganisa, ngokuya ngezidingo ezahlukene, okunikeza ububanzi bokulinganisa obungu-0-100 degrees, 0-500 degrees, 0-3000 degrees ezintathu.

Izinkomba Zobuchwepheshe

Kuyini i-Turbidity?

Ukuvuvukala, isilinganiso sokufiphala koketshezi, kuye kwaqashelwa njengesibonakaliso esilula nesiyisisekelo sekhwalithi yamanzi. Kusetshenziswe ukuqapha amanzi okuphuza, okuhlanganisa nalawo akhiqizwa ukuhlunga amashumi eminyaka. Ukulinganisa ukujiya kuhilela ukusetshenziswa kokukhanya, okunezici ezichaziwe, ukunquma ukuba khona kwenani elincane lezinto ezitholakala emanzini noma kwenye isampula yoketshezi. Ukukhanya kubizwa ngokuthi ukukhanya kwesigameko. Izinto ezikhona emanzini zibangela ukuthi ukukhanya kwesigameko kuhlakazeke futhi lokhu kukhanya okuhlakazekile kuyatholakala futhi kulinganiswe ngokuhambisana nenqubo yokulinganisa elandelekayo. Uma inani lezinto ezitholakala kusampula liphezulu, kulapho ukuhlakazeka kokukhanya kwesigameko kukhulu khona futhi kulapho ukujiya okubangelwayo kuphakeme 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.
