Iindaba - Yintoni inzwa ye-conductivity emanzini?

I-Conductivity yiparamitha yohlalutyo esetyenziswa ngokubanzi kwizicelo ezahlukeneyo, kubandakanywa uvavanyo lokucoceka kwamanzi, ukujongwa kwe-osmosis umva, ukuqinisekiswa kwenkqubo yokucoca, ulawulo lwenkqubo yemichiza, kunye nolawulo lwamanzi amdaka kwimizi-mveliso.

Inzwa ye-conductivity yeendawo ezinamanzi sisixhobo sombane esenzelwe ukulinganisa umbane wamanzi.

Ngokomgaqo, amanzi acocekileyo abonisa ukuhanjiswa kombane okungafunekiyo. I-conductivity yombane yamanzi ngokuyinhloko ixhomekeke ekugxininiseni kwezinto ezi-ionized ezichithwe kuyo-oko kukuthi, iinqununu ezihlawulisiweyo ezifana ne-cations kunye ne-anions. Ezi ion ziphuma kwimithombo efana neetyuwa eziqhelekileyo (umzekelo, i-sodium ion Na⁺ kunye ne-chloride ion Cl⁻), iiminerali (umz., i-calcium ion Ca²⁺ kunye ne-magnesium ion Mg²⁺), iiasidi, kunye neziseko.

Ngokulinganisa i-conductivity yombane, inzwa ibonelela ngovavanyo olungathanga ngqo lweeparameters ezifana ne-total dissolved solids (TDS), i-salinity, okanye ubungakanani bokungcola kwe-ionic emanzini. Amaxabiso aphezulu e-conductivity abonisa ukuxinwa okukhulu kweeyoni ezinyibilikileyo kwaye, ngenxa yoko, ukunciphisa ukucoceka kwamanzi.

UmGaqo wokuSebenza

Umgaqo-siseko osebenzayo we-conductivity sensor usekelwe kuMthetho we-Ohm.

Amacandelo aphambili: I-Conductivity sensors zisebenzisa i-electrode ezimbini okanye ezine-electrode configurations.
1. Ukusetyenziswa kwamandla ombane: Umbane otshintshayo usetyenziswa kwiperi enye yee-electrode (ii-electrode zokuqhuba).
2. Ukufuduka kwe-Ion: Ngaphantsi kwefuthe lendawo yombane, ii-ion kwisisombululo zifudukela kwi-electrodes yentlawulo echaseneyo, ivelisa umbane wombane.
3. Umlinganiselo wangoku: Isiphumo sangoku silinganiswa yinzwa.
4. Ukubalwa kwe-Conductivity: Ukusebenzisa i-voltage esetyenzisiweyo eyaziwayo kunye nomlinganiselo wangoku, inkqubo inquma ukuchasana kombane kwisampuli. I-Conductivity ke ithathwa ngokusekelwe kwiimpawu zejometri zenzwa (indawo ye-electrode kunye nomgama we-inter-electrode). Ubudlelwane obusisiseko bubonakaliswa ngolu hlobo:
Ukuqhuba (G) = 1 / Ukuchasa (R)

Ukunciphisa ukuchaneka kokulinganisa okubangelwa i-electrode polarization (ngenxa yokuphendula kwe-electrochemical kwi-electrode surface) kunye nemiphumo ye-capacitive, iinzwa ze-conductivity zanamhlanje zisebenzisa i-excitation yangoku (AC) eguqukayo.

Iindidi zeeSensors zeConductivity

Kukho iintlobo ezintathu eziphambili ze-conductivity sensors:
• Iimpawu ezimbini ze-electrode zifanelekile kumanzi acocekileyo kunye nemilinganiselo ephantsi yokuqhuba.
Abenzi boluvo be-electrode abane baqeshwe kuluhlu oluphakathi ukuya kwi-high-conductivity kwaye banikezela ukuxhathisa okongeziweyo kwi-fouling xa kuthelekiswa noyilo lwe-electrode ezimbini.
• I-Inductive (i-toroidal okanye i-electrodeless) i-conductivity sensors isetyenziselwa amanqanaba aphakathi ukuya phezulu kakhulu kwaye abonise ukuxhathisa okuphezulu ekungcolisekeni ngenxa yomgaqo wabo wokungadibanisi.

I-Shanghai Boqu Instrument Co., Ltd. iye yazibophelela kwintsimi yokuhlola umgangatho wamanzi iminyaka eyi-18, ivelisa izinzwa zomgangatho wamanzi ezikumgangatho ophezulu eziye zasasazwa kumazwe angaphezu kwe-100 kwihlabathi jikelele. Inkampani ibonelela ngezi ntlobo zintathu zilandelayo zezinzwa zokuqhuba:
