Photoelectric Sensor

A: Qhov chaw uas dhau los ntawm -beam photoelectric sensors yuav tsum zam

1. Cov chaw uas muaj hmoov av ntau;

2. Cov chaw uas muaj cov roj corrosive ntau;

3. Qhov chaw uas muaj dej, roj, thiab tshuaj lom neeg tuaj yeem tawg ncaj qha;

4. Qhov chaw uas muaj lub teeb muaj zog ncaj qha xws li sab nraum zoov lossis hnub ci yam tsis muaj kev ntsuas shading.

Qhov chaw nyob qhov twg qhov kub ntawm ambient hloov tshaj qhov teev ntau yam ntawm cov khoom; qhov chaw uas muaj kev vibration loj thiab cuam tshuam, tab sis tsis muaj kev ntsuas shockproof. Kev ceev faj rau kev siv photoelectric sensor hloov

1. Tsis txhob muaj lub teeb pom kev zoo photoelectric hloov sensors feem ntau tuaj yeem ua haujlwm ruaj khov thaum lub teeb pom kev zoo siab. Txawm li cas los xij, tsis txhob tig ntsej muag lub ntsej muag lub ntsej muag ncaj qha rau cov teeb pom kev zoo xws li lub hnub ci thiab cov teeb ci incandescent. Thaum lub kaum sab xis ntawm lub optical axis ntawm lub sensor (receiver) thiab lub teeb pom kev zoo tsis tuaj yeem hloov pauv, lub shading phaj lossis lub shading raj tuaj yeem ntsia tau ib ncig ntawm lub sensor.

2. Tiv thaiv kev sib nrig sib cuam tshuam Photoelectric beam sensors feem ntau muaj kev ua haujlwm ntawm kev tiv thaiv kev sib nrig sib cuam tshuam, yog li tsis tas yuav txhawj txog kev cuam tshuam kev sib nrig sib. Txawm li cas los xij, thaum ob peb pawg los ntawm -beam infrared photoelectric sensors raug teeb tsa nyob rau hauv tib lub sijhawm thiab nyob ze rau ib leeg, cov pab pawg nyob ib sab thiab kev cuam tshuam kev sib raug zoo yuav tsum raug tiv thaiv. Txoj hauv kev zoo tshaj los tiv thaiv qhov cuam tshuam no yog hla - teeb tsa lub projector thiab lub receiver thiab qhib pab pawg nyob deb thaum muaj ntau tshaj 2 pawg. Tau kawg, siv cov qauv nrog ntau zaus kuj yog ib txoj hauv kev zoo.

3. Daim iav lub kaum sab xis nyhuv Thaum cov khoom yuav tsum ntsuas yog ci los yog ntsib cov hlau du, qhov kev xav tau feem ntau siab heev, uas muaj daim iav - zoo li cov nyhuv. Lub sijhawm no, lub projector thiab cov khoom kuaj pom yuav tsum tau teeb tsa ntawm lub kaum sab xis ntawm 10 mus rau 20 degrees kom nws cov axis kho qhov muag tsis nyob rau ntawm cov khoom kom pom, yog li tiv thaiv kev ua haujlwm tsis raug.

4. Tshem tawm qhov cuam tshuam ntawm cov khoom tom qab Thaum siv lub teeb pom kev zoo diffusion projector thiab receiver, qee zaum lub yees duab reflective sensor yuav tsis tuaj yeem ntes tau ruaj khov vim tias cov khoom pom tau ze rau cov khoom tom qab, lossis qhov sib thooj duab sensor lossis keeb kwm yav dhau yog cov khoom du uas muaj kev cuam tshuam siab. Yog li ntawd, koj tuaj yeem siv qhov kev ncua deb - txwv qhov projector thiab receiver hloov, lossis siv txoj hauv kev xws li txav deb ntawm keeb kwm yav dhau, tshem tawm cov khoom tom qab, pleev xim rau cov khoom tom qab matte dub, lossis sim ua kom cov khoom tom qab ntxhib thiab tsaus kom tshem tawm nws.

A: Tshawb xyuas cov khoom ntawm cov kab ntau lawm lossis cov khoom siv: Photoelectric sensors tuaj yeem tshawb xyuas qhov loj ntawm cov khoom kom pom qhov tsis raug, lossis tsuas yog pom lawv qhov tsis tuaj, nrog rau khaws cov teeb meem xws li misaligned caps ntawm lub raj mis. Lawv tau siv dav hauv cov khoom noj thiab tshuaj lag luam thiab cov chaw ntim khoom.

A: Nws muaj lub neej ntev, kev paub ntev ntev, thiab muaj kev ntseeg siab heev. Nws lub sij hawm teb yog ceev heev, thiab nws raug nqi tsawg.

A: Photoelectric sensors feem ntau muaj lub transmitter uas emits lub teeb thiab lub receiver uas tau txais lub teeb. Thaum lub teeb emission cuam tshuam los yog cuam tshuam los ntawm cov khoom siv ntsuas, nws hloov lub teeb mus txog lub receiver. Lub receiver ntes qhov kev hloov pauv no thiab hloov nws mus rau hauv cov khoom siv hluav taws xob.

A: Photoelectric sensors emit ib lub teeb ntawm lub teeb (pom los yog infrared) los ntawm lawv lub teeb -emitting element. Reflective photoelectric sensors yog siv los ntes cov kab teeb pom kev los ntawm lub hom phiaj. Los ntawm -beam sensors yog siv los ntsuas qhov kev hloov pauv ntawm lub teeb uas tshwm sim los ntawm lub hom phiaj hla lub qhov muag axis.

A: Feem ntau, daim duab - hluav taws xob sensor muaj ob lub ntsiab. Lawv yog cov transmitter (lub teeb ci) thiab receiver (sensor).

A: Lub teeb pom kev zoo muaj lub teeb pom kev zoo, lub teeb pom kev zoo, lub teeb pom kev zoo thiab lub teeb hluav taws xob tso tawm, thiab txhua feem muaj cov haujlwm hauv qab no. Lub photodiode thiab phototransistor ntawm lub teeb receiver tau txais lub teeb tawm ntawm lub teeb ci thiab hloov mus rau hauv lub teeb liab hluav taws xob.

A: Txoj hauv kev yooj yim tshaj plaws los txiav txim siab yuav ua li cas lub raj photoelectric ua haujlwm yog txuas lub multimeter hauv kev ntsuas kev tiv thaiv rau ob qho tib si thiab saib seb qhov kev hloov pauv li cas thaum koj npog lub sensor nrog koj txhais tes, tua lub teeb, thiab lwm yam. Vim tias qhov kev hloov pauv ntau, qhov ntsuas qhov tsis zoo no ua haujlwm zoo ntawm no.

A: Cov xwm txheej hauv qab no tuaj yeem ua rau cov teeb liab tso tawm ntawm cov duab hluav taws xob sensor tsis ruaj khov thaum pom cov khoom:

① Lub zog tsis zoo;

② Kev kuaj xyuas zaus nrawm dhau;

③Size qhov teeb meem ntawm cov khoom yuav tsum tau ntsuas;

④ Cov khoom yuav tsum tau ntsuas tsis nyob rau hauv qhov chaw ruaj khov ntawm lub sensor;

⑤ Kev cuam tshuam hluav taws xob.

Kev tiv thaiv:

① Muab qhov hluav taws xob ruaj khov rau lub ntsuas hluav taws xob, thiab cov khoom siv tam sim no yuav tsum ntau dua qhov kev siv tam sim no ntawm lub sensor.

② Qhov ceev ntawm qhov khoom yuav ntsuas tau dhau los yuav tsum qeeb dua qhov kev teb ceev ntawm lub sensor;

③ Qhov loj ntawm cov khoom yuav tsum tau ntsuas yuav tsum loj dua li tus qauv kuaj pom khoom lossis qhov khoom kuaj pom yam tsawg kawg nkaus;

④ Cov khoom yuav tsum tau ntsuas yuav tsum tau kuaj nyob rau hauv qhov ruaj khov nrhiav kom tau ntau yam ntawm lub sensor;

⑤ Kev tiv thaiv kev tiv thaiv tuaj yeem ua tau, xws li: ua ib daim npog tiv thaiv nyob ib puag ncig ntawm kev sojntsuam, grounding lub siab - cov khoom siv fais fab, thiab lwm yam.
