Mathata a Sensor ea Nitrogen oxide
Tikoloho e thata
Ka lebaka la mocheso o phahameng oa tikoloho ea ho tuka, ke mefuta e itseng feela ea thepa e ka sebetsang in situ. Boholo ba Chex li-sensor tse entsoeng li entsoe ka ceramic mofuta oa metal oxides, ka ntho e tloaelehileng haholo yttria- tsitsitse zirconia (YSZ), eo hajoale e sebelisoang lilemong tse mashome-shome kutlo ea oksijene. YSZ e kopantsoe ka ceramic e teteaneng 'me e tsamaisa li-ion tsa oksijene (O2−) mochesong o phahameng oa pompong e ka bang 400 °C le ho feta. Ho fumana lets'oao ho tsoa ho sensor li-electrode tse phahameng tsa mocheso joalo ka tšepe tse ntle (polatinamo, khauta, kapa Palladium) kapa li-oxide tse ling tsa tšepe li behiloe holim'a metsi 'me lets'oao la motlakase joalo ka phetoho ea motlakase kapa ea hajoale e lekantsoe joalo ka ts'ebetso ea Chex ho tsepamisa maikutlo.
Ho hlokahala kutlo e phahameng le ho tšoarella nako e telele
Maemo a NO a haufi le 100-2000 ppm (likarolo ka milione) le NO2 20–200 ppm sebakeng sa 1–10% O2. Sensor e tlameha ho ba hlokolosi haholo ho nka maemo ana.
Liphephetso tse kholo ho nts'etsopele ea sensor ke khetho, kutlo, botsitso, ho ikatisa, nako ea karabelo, moeli oa ho lemoha, le litšenyehelo. Ntle le moo, ka lebaka la tikoloho e matla ea mollo, sekhahla se phahameng sa phallo ea khase se ka pholisa sensor e fetolang lets'oao kapa e ka senya li-electrode ha nako e ntse e ea. soot likaroloana ka senya thepa.
E 'ngoe ea liphephetso tse kholo tseo lisensara tse joalo tsa khase li tobaneng le tsona ke mongobo. Phello e amanang le karabelo ea lets'oao e itšetlehile haholo ka mofuta oa sensor. Li-sensor tsa electrochemical hangata ha li na matla a mongobo kaha limolek'hule tsa metsi li thusa ho laola khatello ea electrolyte empa ho pepeseha ha nako e telele khase e omileng ho ka fokotsa bongata ba mokelikeli oa electrolyte. Palo e phahameng ea kutloisiso ea sefapano e 'nile ea hlokomeloa ho li-sensor tsa khase ka lebaka la ho tšoana ha mochine oa phapanyetsano ea elektronike pakeng tsa likhase tse shebiloeng le limolek'hule tsa metsi.
