Litaba - Sensor ea conductivity ka metsing ke eng?

Conductivity ke paramente ea tlhahlobo e sebelisoang haholo lits'ebetsong tse fapaneng, ho kenyelletsa tlhahlobo ea bohloeki ba metsi, tlhahlobo ea reverse osmosis, netefatso ea ts'ebetso ea ho hloekisa, taolo ea ts'ebetso ea lik'hemik'hale, le taolo ea metsi a litšila a indasteri.

Sensor conductivity bakeng sa tikoloho ea metsi ke sesebelisoa sa elektronike se etselitsoeng ho lekanya motlakase oa metsi.

Ha e le hantle, metsi a hloekileng a bonts'a motlakase o sa tsotelleng. Ts'ebetso ea motlakase ea metsi haholo-holo e itšetlehile ka bongata ba lintho tse ionized tse qhibilihisitsoeng ho eona-e leng, likaroloana tse qosoang tse kang cations le anions. Li-ion tsena li tsoa mehloling e kang matsoai a tloaelehileng (mohlala, sodium ion Na⁺ le chloride ion Cl⁻), liminerale (mohlala, calcium ions Ca²⁺ le magnesium ion Mg²⁺), acid, le bases.

Ka ho lekanya conductivity ea motlakase, kutlo e fana ka tlhahlobo e sa tobang ea li-parameter tse kang total dissolved solids (TDS), salinity, kapa boholo ba tšilafalo ea ionic metsing. Litekanyetso tse phahameng tsa conductivity li bonts'a bongata bo boholo ba li-ion tse qhibilihisitsoeng, ka lebaka leo, bohloeki ba metsi bo fokotsehile.

Molao-motheo oa ho Sebetsa

Molao-motheo oa ts'ebetso oa sensor ea conductivity o thehiloe ho Molao oa Ohm.

Likarolo tsa bohlokoa: Li-sensor tsa conductivity hangata li sebelisa litlhophiso tsa electrode tse peli kapa tse 'ne.
1. Ts'ebeliso ea motlakase: Matla a motlakase a feto-fetohang a sebelisoa holim'a para e le 'ngoe ea li-electrode (li-electrode tse khannang).
2. Ho falla ha Ion: Tlas'a tšusumetso ea sebaka sa motlakase, li-ion tse tharollo li fallela ho li-electrode tse fapaneng, li hlahisa motlakase.
3. Tekanyo ea hona joale: Nako e hlahisoang e lekanyetsoa ke sensor.
4. Conductivity calculation: Ho sebelisa motlakase o tsejoang o sebelisitsoeng le motlakase o lekantsoeng, tsamaiso e etsa qeto ea ho hanyetsa motlakase oa sampuli. Conductivity joale e nkiloeng ho latela litšobotsi tsa geometri tsa sensor (sebaka sa electrode le sebaka sa inter-electrode). Kamano ea mantlha e hlalosoa e le:
Conductivity (G) = 1 / Resistance (R)

Ho fokotsa ho se nepahale ha litekanyo tse bakoang ke polarization ea electrode (ka lebaka la karabelo ea electrochemical sebakeng sa electrode) le litlamorao tsa capacitive, li-sensor tsa sejoale-joale tsa conductivity li sebelisa excitation ea alternating current (AC).

Mefuta ea li-sensor tsa Conductivity

Ho na le mefuta e meraro ea mantlha ea li-sensor tsa conductivity:
• Li-sensor tse peli tsa electrode li loketse metsi a hloekileng le litekanyo tse tlaase tsa conductivity.
Li-sensor tsa elektrode tse 'ne li sebelisoa bakeng sa mekhahlelo e mahareng ho isa ho e phahameng ea conductivity' me li fana ka khanyetso e matlafalitsoeng ha ho bapisoa le meralo ea li-electrode tse peli.
• Li-conductivity (toroidal kapa electrodeless) li-sensor tsa conductivity li sebelisoa bakeng sa maemo a mahareng ho isa ho a holimo haholo 'me li bontša khanyetso e phahameng ea tšilafalo ka lebaka la molao-motheo oa tekanyo ea ho se kopane.

Shanghai Boqu Instrument Co., Ltd. e ikemiseditse ho lekola boleng ba metsi ka dilemo tse 18, ho etsa disensara tsa boleng bo phahameng ba metsi tse abetsweng dinaheng tse fetang 100 lefatsheng ka bophara. Khamphani e fana ka mefuta e meraro e latelang ea li-sensor tsa conductivity:

The DDG - 0.01 - / - 1.0/0.1
Tekanyo ea conductivity e tlase ho li-sensor tsa 2-electrode
Lisebelisoa tse tloaelehileng: ho lokisa metsi, meriana (metsi bakeng sa ente), lijo le seno (taelo ea metsi le ho lokisetsa), joalo-joalo.

EC-A401
Tekanyo e phahameng ea conductivity ho li-sensor tsa 4-electrode
Lisebelisoa tse tloaelehileng: Mekhoa ea CIP / SIP, mekhoa ea lik'hemik'hale, ho hloekisa metsi a litšila, indasteri ea pampiri (ho pheha le ho laola bleaching), lijo le seno (ho hlahloba karohano ea mekhahlelo).

IEC-DNPA
Sensor e nang le inductive electrode, e hanyetsanang le kutu e matla ea lik'hemik'hale
Lisebelisoa tse tloaelehileng: Mekhoa ea lik'hemik'hale, makhasi le pampiri, ho etsa tsoekere, ho hloekisa metsi a litšila.

Maemo a Konokono a Kopo

Li-sensor tsa Conductivity ke tse ling tsa lisebelisoa tse sebelisoang haholo ho lekola boleng ba metsi, tse fanang ka lintlha tsa bohlokoa likarolong tse fapaneng.

1. Tekolo ea Boleng ba Metsi le Tšireletso ea Tikoloho
- Tekolo ea linōka, matša le maoatle: E sebelisoa ho lekola boleng ba metsi ka kakaretso le ho bona tšilafalo e tsoang ho phallo ea likhoerekhoere kapa ho kenella ha metsi a leoatle.
- Tekanyo ea letsoai: Ke ea bohlokoa lipatlisisong tsa maoatle le tsamaiso ea liphoofolo tsa metsing bakeng sa ho boloka maemo a nepahetseng.

2. Taolo ea Tsamaiso ea Liindasteri
- Tlhahiso ea metsi a hloekileng haholo (mohlala, indastering ea semiconductor le ea meriana): E nolofalletsa ho lekola mekhoa ea tlhoekiso ka nako ea 'nete ho netefatsa hore ho latela litekanyetso tse thata tsa boleng ba metsi.
- Sistimi ea metsi a phepelo ea metsi: E thusa taolo ea boleng ba metsi ho fokotsa sekhahla le ho bola, ka hona e ntlafatsa ts'ebetso ea sistimi le bophelo bo bolelele.
- Sistimi ea phepelo ea metsi a pholileng: E lumella ho lekola likhakanyo tsa khatello ea metsi ho ntlafatsa litekanyetso tsa lik'hemik'hale le ho laola ho tsoa ha metsi a litšila.

- E latela phapang ea boleng ba metsi a tala ho ts'ehetsa moralo o sebetsang oa kalafo.
- E thusa ho laola mekhoa ea lik'hemik'hale nakong ea phekolo ea metsi a litšila ho netefatsa hore ho latela melao le ho sebetsa hantle.

4. Temo le Temo ea Metsi
- E beha leihlo boleng ba metsi a nosetso ho fokotsa kotsi ea ho tlala letsoai mobung.
- E laola maemo a letsoai litsamaisong tsa temo ea metsing ho boloka tikoloho e nepahetseng bakeng sa mefuta ea metsing.

5. Lipatlisiso tsa Saense le Likopo tsa Laboratori
- E ts'ehetsa tlhahlobo ea liteko lithutong tse kang k'hemistri, biology, le mahlale a tikoloho ka litekanyo tse nepahetseng tsa ts'ebetso.
