Capacitive Liquid Level Sensor

Technical Parameter

Khoom Taw Qhia:

Lub capacitive roj theem sensor yog ib qho cuab yeej raws li lub hauv paus ntsiab lus ntawm capacitance tsim los ntsuas cov roj theem hauv cov kua tso kua dej los yog lub thawv. Nws txiav txim siab txog qib roj los ntawm kev ntsuas cov kev hloov pauv hauv qhov muaj peev xwm thiab hloov cov teeb liab no rau hauv cov ntaub ntawv nyeem tau los saib xyuas thiab tswj cov roj qib ntawm cov kua dej cia tank. Hom sensor no feem ntau muaj ob lub electrodes, ib qho saum toj thiab ib qho hauv qab cov kua.

Capacitance yog lub peev xwm los khaws cov nqi hluav taws xob ntawm ob lub conductors. Thaum muaj qhov nruab nrab (xws li kua) nruab nrab ntawm ob lub conductors, lub capacitor yog tsim. Tus nqi capacitance ntawm lub capacitor muaj feem xyuam rau qhov dielectric qhov nruab nrab, qhov chaw tus neeg xyuas pib thiab qhov kev ncua deb ntawm cov conductors.

Capacitive roj theem sensors feem ntau muaj ob lub electrodes: ib tug floating electrode thiab ib tug siv electrode. Lub floating electrode yog mounted saum cov kua, thaum siv electrode yog tsau rau hauv lub thawv. Raws li cov kua nce los yog ntog raws lub thawv, tus nqi capacitance ntawm cov floating electrode thiab cov ntaub ntawv siv electrode hloov.

Thaum cov kua ntim rau hauv lub thawv, ib qho hluav taws xob yog tsim los ntawm cov kua thiab cov floating thiab siv electrodes. Qhov loj ntawm qhov hluav taws xob no nyob ntawm qhov dielectric tas li ntawm cov kua, qhov kev ncua deb ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, thiab thaj tsam ntawm cov ntab electrode. Los ntawm kev ntsuas qhov kev hloov pauv ntawm tus nqi capacitance, cov roj theem siab ntawm cov kua tuaj yeem txiav txim siab.

Capacitive roj qib sensors feem ntau yog nruab nrog lub teeb liab converter lossis ua chav tsev. Chav tsev no yog lub luag haujlwm rau kev hloov pauv qhov kev hloov pauv ntawm tus nqi capacitance mus rau qhov nyeem tau qhov hluav taws xob lossis cov teeb liab digital. Cov teeb liab no tuaj yeem xa mus rau lub khoos phis tawj lossis cov cuab yeej tso saib rau kev tshuaj xyuas ntxiv thiab ua tiav.

Thaum siv capacitive roj qib sensors, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau qee qhov cuam tshuam cuam tshuam. Piv txwv li, qhov kub thiab txias hloov thiab conductivity ntawm qhov nruab nrab tuaj yeem cuam tshuam qhov ntsuas ntawm tus nqi capacitance. Yog li ntawd, hauv cov ntawv thov tshwj xeeb, kev ntsuas tsim nyog yuav tsum tau coj los ntsuas thiab them nyiaj rau cov cuam tshuam cuam tshuam.
