Ho khetha mochine o nepahetseng oa khase

Re lokela ho nahana ka eng ho fumana mochine o loketseng oa khase? o ka sheba likarolo tse latelang.

1. Molao-motheo oa ho lemoha: Li-sensor tsa khale tsa electrochemical le li-sensor tsa semiconductor li ka lekanya mefuta e mengata ea likhase, 'me theknoloji ea sensor e hōlile' me theko e tlaase, empa ho nepahala ha eona ho tlaase le nako ea ho arabela e lieha, 'me ho bonolo ho e fumana. ho sitisoa ke likhase tse ling le mabaka a tikoloho. Sensor e thehiloeng ho boemo bo tiileng ba electrochemistry e na le kutlo le ho nepahala ho betere hape e na le theko e tlase. The non-dispersive Infrared Absorption Principle (NDIR) sensor e na le kutlo e ntle le ho nepahala, empa e theko e boima, 'me hona joale e khona ho lemoha feela karoloana e nyenyane ea mefuta ea khase, e kang CO2, CH4, le li-hydrocarbon tse ling.

2. Ho nepahala le kutloisiso ea detector: Batla lisebelisoa tsa khase tse nang le ho nepahala ho phahameng le kutloisiso. Sena se ka khethoa ka ho sheba lintlha tsa sehlahisoa kapa matšoao a setifikeiti, joalo ka setifikeiti sa ISO 9001 le ho tšoaea CE. Ho feta moo, leka ho khetha lisebelisoa tsa khase tse feto-fetohang le tse khonang ho bona maemo a tlase ho sireletsa bophelo bo botle le polokeho ea basebetsi ba tlhahiso.

3. Botšepehi le nako ea bophelo: Khetha mochine oa khase o nang le botšepehi bo botle le nako e telele ea bophelo. Ho tseba nako ea tiisetso ea mochine, hammoho le litlhahlobo le maikutlo a tsoang ho basebelisi ba bang, ho ka u thusa ho ahlola ho tšepahala ha sehlahisoa.

4. Ts'ebetso le boiketlo ba ts'ebeliso: Nahana ka ts'ebetso le boiketlo ba ts'ebeliso ea detector. Lihlahisoa tse ling li ka ba le bokhoni ba ho rekota le ho hlahloba lintlha, athe lihlahisoa tse ngata li ka fana ka pontšo ea khase. Netefatsa hore na molumo, khanya, alamo ea vibrate ea hlokahala ho latela tlhoko. Alamo e feto-fetohang e loketse.

5. Theko le botumo ba lebitso: Ho nahanoa ka theko le botumo ba lebitso le tsona lia hlokahala. Theko hangata e bonts'a boleng le ts'ebetso ea sehlahisoa, empa ho bohlokoa hape ho bapisa phapang lipakeng tsa mefuta. Ho hlahloba setumo le maikutlo a bareki ho ka u thusa ho khetha mochine o tšepahalang oa khase.

Molao-motheo o sebetsang oa sensor ea khase ea electrochemical e bontšitsoe ka tlase,

Molao-motheo oa li-sensor tsa khase ea electrochemical o kenyelletsa moralo oa li-electrode tse tharo, o nolofalletsang ts'ebeliso e tsoelang pele methalong ea khatello ea khase. Sensor haholo-holo e na le tsamaiso ea li-electrode tse tharo (electrode e sebetsang, electrode ea counter, electrode ea boitsebiso) le electrolyte ea metsi, e sebetsang tlas'a bokhoni bo sa feleng. Limolek'hule tsa khase li hasana ka li-pores ho fihlela eleketrode e sebetsang ea sensor, moo karabelo ea phokotso ea electrochemical e hlahang holim'a elektrode. Li-proton tse hlahisoang ke karabelo li fallela k'haontareng ea eleketrode ka polymer electrolyte, 'me boholo ba lets'oao la hajoale bo lekana ka kotloloho le bongata ba khase e lekantsoeng. Ho latela molao oa Fick, ke = nFDC. Ka hona, ho phalla ha hona joale ho lekana ka ho toba le khatello ea khase e lebisitsoeng, ha electrode ea litšupiso e boloka bokhoni bo sa feleng le potentiostat.

Mona ke tse ling tsa likarolo le litšobotsi tsa Solid-State Electrochemical Gas Sensors,

1. Kutloelo-bohloko e phahameng: E ​​khona ho lemoha boemo bo phahameng boemong ba PPB ka qeto ea ho fihla ho 1ppb, ho lumella ho pepeseha ho tsoelang pele le ho shebella likhase tse phahameng haholo.

2. Karabelo e potlakileng: Nako ea karabo ea sensor e ka ba ka har'a metsotsoana ea 3, ka T90 30s.

3. Botsitso bo botle: Tšebeliso ea nako e telele ha e hlahise litaba tse kang zero drift.

4. Nako e telele ea bophelo: Ho sebelisa theknoloji ea electrolyte e sa sebelisoeng e sa sebelisoeng, ho senyeha ha maikutlo ho fokotsehile nakong ea tšebeliso ea nako e telele.

5. Saese e kopaneng: E ​​nolofalletsa ts'ebeliso ea lisebelisoa tse kopaneng tsa liparamitha tse ngata le ho hokahana le lisebelisoa tse nkehang habonolo le tse ka roaloang.

6. Thibelo e matla ea ho thibela: Ka tšebeliso ea theknoloji e khethehileng ea ho lokisa li-electrode, e na le matla a matla a ho thibela ho kena-kenana le ho thibela ho kena-kenana le lintho tse ling tse nang le khase.

7. Mocheso o pharalletseng: E ​​ka sebetsa ka mokhoa o tloaelehileng tikolohong ea ho tloha ho -40 °C ho isa ho 55 °C.

8. Phapang e phahameng: Tekanyo e feletseng ea moeli, e khotsofatsang ho nepahala ho phahameng ka <± 5% FS.
