Nhau - Chii chinonzi conductivity sensor mumvura?

Conductivity ndiyo inoshandiswa zvakanyanya analytical parameter mumashandisirwo akasiyana-siyana, kusanganisira kuchena kwemvura ongororo, reverse osmosis yekutarisa, yekuchenesa maitiro ekugadzirisa, makemikari process control, uye maindasitiri etsvina manejimendi.

A conductivity sensor yeaqueous environments chinhu chemagetsi chakagadzirirwa kuyera magetsi emvura.

Muchidimbu, mvura yakachena inoratidza isingaite magetsi conductivity. Kugadziriswa kwemagetsi emvura kunonyanya kuenderana nekusangana kwezvinhu ionized zvakanyungudutswa mairi-kureva, masheji emagetsi akadai se cations uye anions. Aya maion anobva kune mamwe maayoni akajairika (semuenzaniso, sodium ions Na⁺ uye chloride ion Cl⁻), zvicherwa (semuenzaniso, calcium ions Ca²⁺ uye magnesium ion Mg²⁺), asidhi, uye mabhesi.

Nekuyera mafambisirwo emagetsi, iyo sensor inopa kuongororwa kusinganangana kwema paramita akadai seyakazara yakanyungudika solids (TDS), salinity, kana huwandu hwekusvibiswa kweionic mumvura. Higher conductivity values inoratidza kuwanda kweiyoni yakanyungudika uye, nekudaro, kuderedzwa kwemvura kuchena.

Kushanda Nheyo

Iyo yakakosha yekushandisa musimboti we conductivity sensor yakavakirwa paOhm's Law.

Zvikamu zvakakosha: Conductivity sensors inowanzo shandisa maviri-electrode kana mana-electrode masisitimu.
1. Voltage application: An alternating voltage inoshandiswa pane imwe peya yemagetsi (maelectrodes ekutyaira).
2. Ion migration: Pasi pesimba remunda wemagetsi, ions mumhinduro inotamira kune electrodes yeanopesana nechaji, ichigadzira magetsi.
3. Chiyero chezvino: Ikozvino inoguma inoyerwa ne sensor.
4. Conductivity calculation: Kushandisa inozivikanwa inoshandiswa voltage uye yakayerwa ikozvino, iyo inogadzirisa inogadzirisa magetsi ekuenzanisa. Conductivity inobva yatorwa zvichibva pane sensor's geometric maitiro (electrode area uye inter-electrode distance). Hukama hwakakosha hunoratidzwa se:
Kuitisa (G) = 1 / Resistance (R)

Kuti uderedze kuyerwa kusarongeka kunokonzerwa ne electrode polarization (nekuda kwe electrochemical reactions pa electrode surface) uye capacitive mhedzisiro, yemazuva ano conductivity sensors inoshandisa alternating current (AC) excitation.

Mhando dzeConductivity Sensors

Kune matatu ekutanga marudzi e conductivity sensors:
• Maviri-electrode sensors akakodzera kune yakakwirira-yakachena mvura uye yakaderera-conductivity zviyero.
Mana-electrode sensors anoshandiswa kwepakati-kusvika-high-conductivity renji uye anopa kukwidziridzwa kuramba kune fouling zvichienzaniswa neaviri-electrode dhizaini.
• Inductive (toroidal kana electrodeless) conductivity sensors inoshandiswa kune yepakati kusvika kune yakanyanya conductivity mazinga uye inoratidzira kukwirira kwekudzivirira kusvibiswa nekuda kwekusava nekubatana kwekuyera nheyo.

Shanghai Boqu Instrument Co., Ltd. yakazvipira kumunda wekutarisa kunaka kwemvura kwemakore gumi nemasere, inogadzira ma sensors emhando yepamusoro yemvura akagoverwa kunyika dzinopfuura zana pasi rose. Iyo kambani inopa matatu anotevera marudzi e conductivity sensors:

Iyo DDG - 0.01 - / - 1.0/0.1
Kuyera kwepasi conductivity mu 2-electrode sensors
Mashandisirwo akajairika: kugadzirira mvura, mishonga (mvura yejekiseni), chikafu nechinwiwa (mutemo wemvura uye kugadzirira), nezvimwe.

EC-A401
High conductivity kuyerwa mu 4-electrode sensors
Maitiro ekushandisa: CIP / SIP maitiro, maitiro emakemikari, kurapwa kwemvura yakasviba, iyo indasitiri yemapepa (kubika uye bleaching control), chikafu uye chinwiwa (phase separation monitoring).

IEC-DNPA
Inductive electrode sensor, inoshingirira kune yakasimba kemikari corrosion
Yakajairika mashandisirwo: Kemikari maitiro, pulp uye bepa, kugadzira shuga, kuchenesa mvura.

Minda Yekushandisa Yakakosha

Conductivity sensors ndeimwe yezvishandiso zvinonyanya kushandiswa mukutarisisa mhando yemvura, ichipa data rakakosha pane dzakasiyana siyana zvikamu.

1. Kuongorora Kwemhando Yemvura uye Kuchengetedzwa Kwezvakatipoteredza
- Kutariswa kwenzizi, madziva, uye nyanza: Inoshandiswa kuongorora huwandu hwemvura uye kuona kusvibiswa kubva mukubuda kwetsvina kana kupinda mumvura yegungwa.
- Salinity kuyerwa: Kwakakosha mukutsvagisa oceanographic uye aquaculture manejimendi kuchengetedza mamiriro akakwana.

2. Industrial Process Control
-Kugadzirwa kwemvura yakachena (semu semiconductor uye maindasitiri emishonga): Inogonesa kutarisa-nguva chaiyo kwemaitiro ekucheneswa kuti ive nechokwadi chekutevedzwa kwemhando dzakaomarara dzemvura.
- Boiler feedwater masisitimu: Inofambisa kudzora kwemhando yemvura kudzikisa kuyera uye ngura, nekudaro ichiwedzera mashandiro ehurongwa uye hupenyu hurefu.
- Inotonhorera kutenderera kwemvura masisitimu: Inobvumira kutarisisa kwehuwandu hwehuwandu hwemvura kukwirisa kemikari dosing uye kudzora kubuda kwetsvina.

3. Mvura Yekunwa uye Kurapa Kwemvura Yakasviba
- Inoteedzera misiyano yemhando yemvura yakasvibirira kutsigira kuronga kwekurapa kunoshanda.
- Inobatsira mukudzora maitiro emakemikari panguva yekurapa kwemvura yakasviba kuti ive nechokwadi chekuteedzera kutevedza uye kushanda zvakanaka.

4. Zvekurima uye Aquaculture
- Inotarisa kunaka kwemvura yekudiridza kuderedza njodzi yemunyu wevhu.
- Inogadzirisa mazinga emunyu mumagadzirirwo emumvura kuchengetedza nzvimbo yakakwana yezvipenyu zvemumvura.

5. Scientific Research uye Laboratory Applications
-Inotsigira ongororo yekuyedza muzvidzidzo zvakaita sekemesitiri, biology, uye sainzi yezvakatipoteredza kuburikidza nemayero chaiwo ekuita.
