    Kev tsim nyog tau sensor

     

    1.Cov txoj hauj lwm sensor yog qhov chaw tsis muaj kev sib tiv tauj, uas feem ntau muaj ntawm peb ntu: qhov chaw kuaj pom, txheej tiv thaiv thiab lub khauj khaum. Lawv tuaj yeem ntsuas qhov tseeb ntawm lub hom phiaj, tab sis tsuas yog tus kwv. Yog tias ntsuas qhov khoom tsis yog kev coj ua, nws tseem muaj txiaj ntsig zoo rau kev ntsuas nws cov tuab los yog ntom.

     

    2.When ntsuas cov khoom siv ua haujlwm, cov kos duab kos tsis muaj dab tsi ua rau cov khoom siv, vim yog lub peev xwm kev txav chaw, txhua tus neeg saib xyuas yog tib lub electrode. Qhov no zoo ntawm sensor feem ntau yog siv hauv disk tsav, semiconductor thev naus laus zis thiab kev ntsuas siab muaj qhov tseeb thiab cov lus teb zaus. Thaum siv los ntsuas cov tsis yog-photasitection sensors feem ntau yog siv los kuaj cov ntawv cim, tsho tshaj plaws thiab ntsuas cov tuab ntawm daim ntawv lossis zaj duab xis.

     

    3.Cov txoj hauj lwm sensor yog xub pib ntsuas qhov linan kev deb, thiab kev ntsuas tau ua tiav los ntawm kev siv cov yam hluav taws xob ntawm kev ua haujlwm. Lub peev xwm ntawm ib qho khoom siv los khaws tus nqi yog hu ua capacitance. Ib lub capacitor ntaus ntawv rau kev them nqi yog ib lub capacroritor. Lub peev xwm capacitance ntawm lub phaj cap capacitor yog ncaj qha rau cov electrode cheeb tsam thiab dielectric tas li, thiab inversely proportional rau qhov kev ncua deb ntawm electrodes. Yog li ntawd, thaum qhov kev ncua deb ntawm cov electrodes hloov, lub peev xwm kuj hloov. Hauv ib lo lus, capensitive txoj hauj lwm sensor siv cov xeeb ceem no los ua tiav txoj haujlwm nrhiav.

     

    4.a raug capacitive txoj hauj lwm sensor suav nrog ob lub tshuab hlau, nrog huab cua ua dielectric. Ib lub tshuab hluav taws xob yog lub phaj hlau, thiab lwm yam hluav taws xob ntawm lub capacitor yog tsim ntawm cov khoom lag luam uas raug kuaj pom. Thaum muaj hluav taws xob yog thov ntawm cov neeg tshaj tawm cov phiaj, ib daim teb hluav taws xob tau tsim los ntawm cov paib, thiab ob daim phiaj khw uas raug nqi uas tsis zoo. Peev xwm txoj hauj lwm sensor feem ntau yog saws ac voltage, uas ua rau tus nqi hloov pauv polarity tuaj yeem kuaj pom los ntawm ntsuas qhov ntsuas ntawm ob daim phiaj.

     

    5.Qhov muaj peev xwm siv tau los ntawm qhov kev ncua deb ntawm cov phiaj, lub dielectric tas li ntawm dielectric thiab qhov deb ntawm cov phiaj. Hauv feem ntau cov sensors, thaj chaw thiab dielectric tas li ntawm electrode phaj yuav tsis hloov, tsuas yog qhov kev ncua deb yuav cuam tshuam ntawm electrode thiab lub hom phiaj. Yog li ntawd, kev hloov pauv ntawm capacitance tuaj yeem qhia lub hom phiaj. Los ntawm kev ntsuas hluav taws xob, cov zis hluav taws xob hluav taws xob ntawm lub sensor muaj kev sib raug zoo linar nrog qhov kev ncua deb ntawm lub rooj sib tham thiab lub hom phiaj. Qhov no yog qhov rhiab ntawm lub sensor. Nws qhia txog qhov sib piv ntawm cov zis hluav taws xob hloov mus rau txoj haujlwm hloov. Chav tsev feem ntau yog 1v / micron, uas yog, cov zis voltage hloov 1v txhua 100 microns.

     

    6.Vim ib qho hluav taws xob uas siv rau qhov chaw nrhiav kom pom, thaj chaw sib txawv yuav tsim tawm ntawm cov khoom kuaj pom. Txhawm rau kom txo cov kev cuam tshuam, txheej txheej tiv thaiv tau ntxiv. Nws siv tib lub tshuab hluav taws xob ntawm ob qho xaus ntawm thaj chaw kuaj kom tiv thaiv hluav taws xob teb hauv qhov chaw nrhiav kom pom. Cov neeg saib xyuas sab nraud yuav tsim hluav taws xob cov chaw kuaj hluav taws xob nrog cov txheej txheem tiv thaiv thiab yuav tsis cuam tshuam nrog hluav taws xob teb ntawm lub hom phiaj thiab qhov chaw kuaj pom. Vim yog cov txheej tiv thaiv, hluav taws xob teb hauv qhov chaw kuaj pom yog conical. Qhov chaw ua haujlwm ntawm hluav taws xob tawm ntawm hluav taws xob teb tawm los ntawm kev nrhiav cov electrode yog 30% loj dua li cov ncauj lus nrhiav. Yog li ntawd, txoj kab uas hla ntawm cov khoom kuaj yuav tsum muaj tsawg kawg 30% loj dua li qhov kev kuaj pom ntawm lub sensor.
