Electrochemical Dissolved Oxygen Sensor

Sensa sena sa indasteri se qhibilihang ka oksijene se sebelisa mokhoa oa khale oa ho metha oa amperometric electrochemical, o nang le ts'ebetso e kopaneng ea mats'oao a dijithale, e hahiloeng-ka tefello ea mohatsela le sebopeho sa IP68 se sa keneleng metsi. E ts'ehetsa maemo a tloaelehileng a RS485 Modbus-RTU digital output, e nang le botsitso bo holimo, low drift, anti{5}}tšitiso e matla le bophelo bo bolelele ba ts'ebeletso. E sebelisoa haholo ho aquaculture, ho hloekisa likhoerekhoere, ho beha leihlo tikoloho, ho noa joala le mekhoa ea metsi ea meriana, 'me e ka hokahanngoa ka ho toba le balaoli ba lihlopha tsa PLC, DCS le MTW.

Sensor ena ea liindasteri{{0}morero ea "electrochemical dissolved oxygen" e etselitsoe ho hlahloba nako e telele-oksijene e qhibilihisitsoeng inthaneteng libakeng tse fapaneng tsa metsi. E sebelisa tsamaiso ea amperometric three-electrode electrochemical electrode (working electrode, reference electrode, counter electrode), e thibelang polarization ea electrode ka katleho le ho fokotsa ho kena-kenana le hydrogen sulfide, carbon dioxide le lintho tse ling, ho netefatsa hore tekanyo e tsitsitseng le e nepahetseng. -membrane e sebetsang hantle haholo e arola lintho tse thata tse emisitsoeng le lintho tse silafatsang, e sireletsang motlakase o ka hare oa electrolyte le electrode.

E hahiloe{{0}ka hodimo-sensoro e nepahetseng ya mocheso e hlokomela{2}}matšeliso a feletseng a mefuta e fapaneng ya thempereichara, e lokisa diphoso tsa ditekanyo tse bakilweng ke ho fetoha ha mocheso wa metsi. Sesebelisoa sena kaofela se sebelisa mokhoa oa ho lokisa matshwao a dijithale le moralo oa ho itšehla thajana oa motlakase, o nang le bokhoni bo matla ba ho thibela{4}}khatiso ea motlakase, e ts'ehetsa phetisetso ea nako e telele-ka RS485 Modbus{7}}RTU. Ntlo e entsoe ka corrosion-resistant PPS/PEEK engineering steel and 316L stainless steel, e boreleli{11}}e thibelang litšila, e loketse ho kenya{12}ka metsi nako e telele.

E ts'ehetsa maemo a tloaelehileng a-ntlha le lintlha tse peli-tse lekanyelitsoeng{1}}ka oksijene e se nang letho, khokahanyo ea oksijene e tletseng), e nang le matla a ho lekanya{2}mesebetsi ea ho itlhokomela le mathata{3}.

E na le botsitso bo babatsehang mme e ka matha e sa kgaotse nako e telele matamong a aquaculture, ditanka tsa aeration le ditanka tsa biochemical reaction.
