Lub siab -kub qhov sib thooj sensor, uas siv cov khoom siv hluav taws xob los ze qhov no tuaj yeem tsim hluav taws xob hluav taws xob nyob ze ntawm qhov hloov, yuav tsim ib qho eddy tam sim no hauv cov khoom. Hauv eddy-tam sim no teb qhov sib thooj sensor, qhov hloov pauv hloov hauv qhov ntsuas hluav taws xob kom paub tias muaj tus neeg xyuas pib thiab tom qab ntawd tswj qhov hloov pauv kom qhib lossis kaw. Txoj kev hloov no tuaj yeem ntes cov khoom uas yuav tsum tau ua. HallThaum ib qho khoom sib nqus nyob ze rau ntawm qhov hloov, Hall nyhuv hauv qhov ntsuas hluav taws xob tau ua rau ntawm qhov chaw ntawm qhov hloov Hall lub caij, kom lub xeev hloov pauv, txhawm rau txhawm rau txheeb xyuas qhov muaj nyob ntawm cov khoom sib nqus nyob ze, thiab tom qab ntawd tswj qhov hloov mus qhib lossis tawm. Yuav tsum yog cov khoom ntawm cov hlau sib thooj sensor kuaj khoom.
Nws yog ib qho uas tsis yog -kev sib cuag, nrawm, tsis yog- tswj kev puas tsuaj ntawm ntau yam khoom khib nyiab, kua thiab pob tshab lub cev, lub cev dub, lub cev mos thiab cov khoom siv xws li lub teeb txias txias, infrared, liab, ntsuab thiab xiav lub teeb, xws li haus luam yeeb thiab txav mus los. Me me, kev pab lub neej ntev, siab precision, ceev teb ceev, ntev nrhiav kom tau deb, muaj zog kho qhov muag, hluav taws xob thiab sib nqus cuam tshuam muaj peev xwm.
Los ntawm tib neeg txoj kev hlub, ntau thiab ntau dua nyob rau hauv peb lub neej, nws yog siv los ntes cov khoom los thaiv lossis cuam tshuam cov kab teeb, hu ua txoj hauv kev ntawm synchronous circuitry, txhawm rau kuaj pom cov khoom. Cov khoom tsis txwv rau cov hlau, thiab txhua yam khoom uas cuam tshuam lub teeb tuaj yeem kuaj tau. Lub photoelectric hloov pauv hloov pauv cov tswv yim tam sim no mus rau hauv qhov hluav taws xob kho qhov muag tawm los ntawm lub transmitter, thaum lub zog ntawm lub receiver txuas ntxiv raws li lub teeb tau txais lossis cov khoom siv corrosive. Nyob rau hauv kev nyab xeeb ntawm qhov zoo tib yam photoelectric hloov pa taws tswb, peb feem ntau siv nws los xam tus naj npawb ntawm kev txav ntawm caj npab neeg hlau.
