LEEM-4 Apparatus of Measuring Liquid Conductivity

Lus piav qhia luv luv:

Cov kev sim ntsuas ntsuas cov kua conductivity yog ib hom kev qhia physics kev sim qhia cov cuab yeej nrog cov tswv yim zoo ntawm lub cev, kev sim ua kom zoo, ntau cov ntsiab lus ntawm kev sim ua kom muaj peev xwm, thiab siv tau cov txiaj ntsig.Lub sensor siv nyob rau hauv lub ntsuas yog tsim los ntawm ob lub nplhaib hlau alloy, txhua lub nplhaib yog qhov txhab nrog ib pab pawg ntawm cov coils, thiab cov lem ntawm ob pawg ntawm cov coils yog tib yam, tsim ib qho kev sib nrig sib inductance kua conductivity ntsuas sensor.Lub sensor yog txuas nrog tsawg zaus sinusoidal alternating tam sim no, thiab lub sensor electrode tsis nyob rau hauv kev sib cuag nrog cov kua yuav tsum tau ntsuas, yog li tsis muaj polarization nyob ib ncig ntawm lub sensor.Lub ntsuas ntsuas hluav taws xob tsim los ntawm kev sib nrig sib inductance sensor tuaj yeem ntsuas qhov conductivity ntawm cov kua kom raug thiab tuaj yeem siv tsis tu ncua ntev.Cov kua conductivity tsis siv neeg ntsuas ntsuas raws li txoj cai no tau siv dav hauv kev lag luam roj av, tshuaj lom neeg kev lag luam thiab lwm yam.
