Ni irihe hame ry'ubumenyi rigomba gutozwa mugihe cyo gukoresha metero yimikorere?Ubwa mbere, kugirango wirinde electrode polarisiyasi, metero itanga ibimenyetso bya sine bihamye cyane kandi bigashyirwa kuri electrode.Umuyoboro unyura muri electrode uringaniza nubushobozi bwumuti wapimwe.Nyuma ya metero ihinduye ikigezweho kiva mumashanyarazi yihuta cyane ikora mumashanyarazi ya signal, Nyuma ya progaramu igenzurwa na progaramu ya signal amplification, fonctionnement-fonctionnement no kuyungurura, ibimenyetso bishobora kwerekana imiyoboro yabonetse;microprocessor ihinduranya ikoresheje uburyo bwo guhinduranya ibimenyetso by'ubushyuhe hamwe n'ikimenyetso cyo gutwara.Nyuma yo kubara no kwishyurwa ubushyuhe, igisubizo cyapimwe kiboneka kuri 25 ° C.Agaciro kayobora mugihe hamwe nubushyuhe bwigihe.
Umuriro w'amashanyarazi utera ion kugenda mubisubizo byapimwe bitangwa na electrode ebyiri zihuye neza nigisubizo.Ihuriro ryo gupima electrode rigomba kuba rikozwe mubikoresho birwanya imiti.Mu myitozo, ibikoresho nka titanium bikoreshwa kenshi.Gupima electrode igizwe na electrode ebyiri yitwa Kohlrausch electrode.
Igipimo cyimyitwarire gikeneye gusobanura ibintu bibiri.Imwe ni uburyo bwo gukemura, naho ubundi ni isano ya geometrike ya 1 / A mugisubizo.Imiyoboro irashobora kuboneka mugupima amashanyarazi na voltage.Iri hame ryo gupima rikoreshwa muburyo bwo kwerekana ibikoresho byapimwe.
Kandi K = L / A.
A —— Isahani ikora ya electrode yo gupima
L —— Intera iri hagati yamasahani abiri
Agaciro kibi bita selile ihoraho.Imbere yumuriro umwe wamashanyarazi hagati ya electrode, electrode ihoraho irashobora kubarwa nuburinganire bwa geometrike.Iyo amasahani abiri ya kare afite ubuso bwa 1cm2 yatandukanijwe na 1cm kugirango akore electrode, ihoraho ryiyi electrode ni K = 1cm-1.Niba agaciro kayobora G = 1000μS yapimwe niyi electrode, noneho ubwikorezi bwumuti wapimwe K = 1000μS / cm.
Mubihe bisanzwe, electrode ikora igice cyumuriro w'amashanyarazi igice kimwe.Muri iki gihe, selile ihoraho igomba kugenwa nigisubizo gisanzwe.Ibisubizo bisanzwe mubisanzwe ukoresha igisubizo cya KCl.Ibi ni ukubera ko ubushobozi bwa KCl butajegajega kandi bwuzuye mubushyuhe butandukanye.Umuyoboro wa 0.1mol / l KCl kuri 25 ° C ni 12.88mS / CM.
Umwanya witwa amashanyarazi adahuje (nanone bita umurima uzerera, umurima utemba) ntahoraho, ariko ujyanye nubwoko hamwe nubunini bwa ion.Kubwibyo, electrode yumurima ityaye niyo electrode mbi cyane, kandi ntishobora guhaza ibikenewe mugupima kwinshi binyuze muri kalibrasi imwe.
2. Ni ubuhe buryo bwo gukoresha bwa metero yo gutwara?
Imirima ikoreshwa: Irashobora gukoreshwa cyane mugukomeza gukurikirana indangagaciro zogutwara ?? mubisubizo nkimbaraga zumuriro, ifumbire mvaruganda, metallurgie, kurengera ibidukikije, imiti, ibinyabuzima, ibiryo n'amazi ya robine.
3.Ni ubuhe buryo selile ihoraho ya metero yimikorere?
"Ukurikije formula K = S / G, selile ihoraho K irashobora kuboneka mugupima imyitwarire ya G ya electrode ya elegitoronike yibanda kumurongo wa KCL.Muri iki gihe, imiyoboro ya S ya KCL irazwi.
Electrode ihoraho ya sensor ya sensororo isobanura neza imiterere ya geometrike ya electrode ebyiri za sensor.Nicyo kigereranyo cyuburebure bwikitegererezo mugace gakomeye hagati ya electrode 2.Ihindura mu buryo butaziguye ibyiyumvo no kumenya neza ibipimo.Gupima ingero zifite ubushobozi buke bisaba selile nkeya.Gupima ingero zifite ubushobozi buke bisaba selile ndende.Igikoresho cyo gupima kigomba kumenya selile ihoraho ya sensor ihuza kandi igahindura ibisobanuro byo gusoma.
4. Ni ubuhe bwoko bw'utugingo ngengabuzima twa metero zitwara?
Electrode ya electrode ebyiri nubu ni ubwoko bukoreshwa cyane na electrode mu Bushinwa.Imiterere yubushakashatsi bubiri bwa electrode ya elegitoronike ni ugushushanya amabati abiri ya platine kumpapuro zibiri zibangikanye cyangwa urukuta rwimbere rwikirahuri kizengurutse kugirango uhindure urupapuro rwa platine Agace nintera irashobora gukorwa mumashanyarazi ya electrode ifite agaciro gahoraho.Mubisanzwe hariho K = 1, K = 5, K = 10 nubundi bwoko.
Ihame rya metero yimikorere ni ngombwa cyane.Mugihe uhisemo ibicuruzwa, ugomba no guhitamo uruganda rwiza.
