Cov cuab yeej siv rau kev ntsuas kev ntsuas ua kua yog ib hom kev paub tseeb ntawm lub cev kev sim qhia nrog lub tswv yim lub cev muaj zog, cov tswv yim hais txog kev sim, ntau yam kev kawm ntawm kev siv tes ua kev muaj peev xwm, thiab cov ntawv thov muaj txiaj ntsig. Lub sensor siv nyob rau hauv cov twj paj nruag muaj ob lub suab sib xyaw hlau sib dhos, txhua lub nplhaib sib xyaw nrog ib pawg coils, thiab qhov hloov ntawm ob pawg ntawm coils yog tib yam, ua ib qho hollow kev sib xyaw inductance kua conductivity ntsuas sensor. Lub sensor tau txuas nrog lub zaus tsawg sinusoidal hloov qhov tam sim no, thiab lub ntom ntom ntom hluav taws xob tsis nyob hauv kev sib cuag nrog cov kua uas yuav ntsuas, yog li tsis muaj qhov sib tsoo ib ncig ntawm lub ntsuas. Lub 'meter' conductivity tsim ntawm kev sib nrig sib xyaw inductance tuaj yeem ntsuas qhov conductivity ntawm cov kua ua kom raug thiab tuaj yeem siv txuas ntxiv mus ntev. Cov kua roj conductivity automatic ntsuas qhov ntsuas raws li lub hauv paus ntsiab lus no tau siv dav hauv cov roj av, kev lag luam chemical thiab lwm yam.

Muaj nuj nqi

1. Nkag siab thiab ua pov thawj ua haujlwm ua haujlwm ntawm kev sib nrig sib txuam ua kua ua kua; tau txais cov kev sib raug zoo ntawm lub zog tso tawm voltage thiab kua conductivity; thiab nkag siab txog cov ntsiab lus tseem ceeb ntawm lub cev thiab kev cai lij choj xws li Faraday txoj cai ntawm kev siv hluav taws xob, Ohm txoj cai thiab cov ntsiab cai ntawm kev hloov pauv.

2. Calibrate lub sib-ua kua ua kua conductivity sensor nrog npliag txheem resistors.

3. Ntsuas qhov tseeb ntawm kev coj ua ntawm cov dej qab ntsev ua kom haum ntawm chav sov.

4. Txais kev sib thooj ntawm kev coj ua thiab kub ntawm cov dej ntsev tov (yeem).
