Qhov sib thooj hloov pauv yog ib qho sensor uas kuaj pom muaj lub hom phiaj yam tsis muaj kev sib cuag ntawm lub cev. Nws yog dav siv nyob rau hauv industrial automation, logistics sorting, kev ruaj ntseg systems, thiab lwm yam teb. Nws lub luag haujlwm tseem ceeb yog kom nkag siab qhov sib thooj ntawm ib qho khoom los ntawm electromagnetic induction, kev hloov pauv, lossis cov nyhuv photoelectric, thiab tso tawm cov teeb liab hloov, yog li ua tiav tsis yog - tiv tauj nrhiav thiab tswj.
Raws li lawv cov kev khiav hauj lwm txoj cai, qhov sib thooj keyboards feem ntau muab faib ua plaub pawg: inductive, capacitive, photoelectric, thiab sib nqus. Inductive sib thooj keyboards siv lub hauv paus ntsiab lus ntawm electromagnetic induction. Thaum ib qho khoom siv hlau nkag mus rau qhov kev tshawb pom, qhov tsis sib xws ntawm lub oscillator Circuit Court hloov, ua rau qhov hloov pauv. Lawv tsim nyog rau kev tshawb nrhiav cov khoom siv hlau. Capacitive sib thooj hloov qhov kev nkag siab lub hom phiaj los ntawm kev kuaj xyuas cov kev hloov pauv ntawm cov khoom siv hluav taws xob thiab cov khoom siv. Lawv tuaj yeem ntes tsis tau tsuas yog hlau xwb tab sis kuj tsis yog - cov khoom siv xws li plastics thiab kua, txuas ntxiv lawv daim ntawv thov ntau yam. Photoelectric sib thooj keyboards cia siab rau kev cuam tshuam los yog kev xav ntawm lub teeb txoj kev ntawm lub transmitter thiab receiver los txiav txim seb muaj ib yam khoom. Lawv feem ntau siv los kuaj pom cov khoom pob tshab lossis cov khoom muaj kev cuam tshuam. Sib nqus sib sib zog nqus hloov pauv nyob ntawm kev hloov pauv hauv magnetic teb thiab tsim tshwj xeeb los kuaj xyuas cov khoom sib nqus lossis cov khoom siv hlau nplaum.
Hauv kev siv tswv yim, kev xaiv ntawm qhov sib thooj hloov yuav tsum coj mus rau hauv tus account qhov deb ntawm kev tshawb nrhiav, ib puag ncig, thiab cov yam ntxwv ntawm lub hom phiaj. Piv txwv li, inductive keyboards yog tsim nyog rau siab - precision metal detection tab sis muaj kev cuam tshuam rau muaj zog electromagnetic cuam tshuam. Capacitive keyboards yog rhiab heev rau cov av noo thiab xav tau kev tiv thaiv kom raug. Photoelectric keyboards xav tau txoj kev kho qhov muag tsis pom kev thiab tsim nyog rau qhov chaw huv si. Thaum lub sij hawm kev teeb tsa, qhov ntsuas qhov deb thiab qhov rhiab heev yuav tsum tau hloov kho raws li cov chaw tsim khoom cov lus qhia, thiab kev ua haujlwm yuav tsum raug tiv thaiv los ntawm lub teeb muaj zog, kev co, lossis cov khoom corrosive.
Cov kev sib txuas sib txuas, vim lawv tsis yog -kev sib cuag, teb ceev ceev, thiab lub neej ntev, tau dhau los ua cov khoom tseem ceeb hauv kev tswj hwm niaj hnub no. Kev xaiv tsim nyog thiab kev teeb tsa tus qauv tuaj yeem txhim kho kev ntseeg tau zoo thiab muab kev txhawb nqa rau kev tsim khoom lag luam zoo.
