4 Electrode Conductivity Sensor
Sensara sa 4 electrode conductivity se sebelisa tekhenoloji e tsoetseng pele ea ho metha-electrode, e felisang tšitiso ea polarization 'me e loketse tsamaiso e phahameng, lerata le phahameng le metsi a silafetseng.
Mefuta e mengata ea ho metha, e sa angoeng habonolo ke litšila le litšila tse phelang. Mekhahlelo e mengata ea metsi a litšila a liindasteri, brine, metsi a pholileng le metsi a tšebetso ea lik'hemik'hale. 316L ntlo ea tšepe e sa tsitsang, e hahiloeng-ka matšeliso a mocheso, IP68 e sa keneleng metsi, 3/4" NPT thread, RS485 kapa 4–20mA ea boikhethelo.
4-electrode conductivity sensor e emela maemo a khauta bakeng sa tekanyo e nepahetseng le e fapaneng ea conductivity. Ka ho arola-mesebetsi ea hajoale ea ho tsamaisa le ea ho lemoha motlakase, moralo ona o hlola meedi ea lisensara tse 2 tsa motlakase, ho fana ka ts'ebetso e phahameng ka ho fetesisa mekhoeng e mengata e fapaneng, ho tloha ho metsi a pholileng ho ea ho litharollo tse kopaneng.
Kamoo e Sebetsang Kateng: Molao-motheo oa Karohano
Tlhahiso ea mantlha ea sensor ea 4-electrode e ka har'a li-electrode tsa eona tse 'ne tse ikhethileng, tseo hangata li entsoeng ka graphite kapa tšepe e sa hloekang. Tsena li hlophisitsoe ka lipara tse peli tse ikemetseng:
1. Li-Electrode tsa Kantle tsa Hona Joale: Motlakase o mong (AC) o sebelisoa ho pholletsa le li-electrode tse peli tse ka ntle, o khanna hona joale ka tharollo.
2. Li-electrode tsa Inner Voltage: Li-electrode tse peli tse ka hare li lekanya ho theoha ha motlakase ka tharollo pakeng tsa tsona.
Karohano ena ke senotlolo. Kahobane motlakase o lekanngoa ka-sekoere-khōlō se sa sebetseng hantle, tekanyo ha e amehe ke polarization kapa ho hanyetsa ha li-electrode. Conductivity e baloa ka kotloloho ho tsoa ho motlakase o lekantsoeng le motlakase o tsejoang o sebelisoa, ho ipapisitsoe le Molao oa Ohm (G=I/U
Lisebelisoa tsa mantlha
Phekolo ea Metsi le Litšila:
Ho beha leihlo methati eohle ea kalafo, ho tloha ho tse nang le tšusumetso le litšila limeleng tsa masepala ho isa taolong ea metsi a litšila a indasteri. Ho hanyetsa ha bona ho senyeheng ke letlotlo le leholo tikolohong ena.
Tšebeliso ea Lik'hemik'hale le Meriana:
Tlhokomelo e nepahetseng ea li-acids, alkalis, le matsoai, hammoho le ho laola Kente ea Lik'hemik'hale le Ho Hloekisa-ka-Sekhoa sa Place (CIP).
Pheliso ea Matla:
Ho netefatsa bohloeki bo feteletseng ba metsi a phepelo ea liboli le ho beha leihlo condensate ea mouoane ho thibela kutu e theko e boima le ho eketseha ha li-turbine le li-heaters tsa mocheso.
Lijo le Seno:
Lisensara tsa bohloeki-li sebelisoa ho laola boleng ba sehlahisoa, ho arola likarolo, le ho beha leihlo lits'ebetso tsa ho hloekisa, ho fihlela maemo a thata a bohloeki (mohlala, 3-A, EHEDG).
Environmental Monitoring: Measuring salinity and total dissolved solids (TDS) in surface water, groundwater, and seawater.
