Ultrasonic sensor

Lub ultrasonic sensor yog lub sensor uas hloov cov teeb liab ultrasonic mus rau lwm cov teeb liab zog, feem ntau yog cov teeb liab hluav taws xob. Cov ultrasonic waves yog cov mechanical waves nrog cov zaus co siab dua 20kHz. Lawv muaj cov yam ntxwv ntawm cov zaus siab, luv luv wavelength, tsawg kawg nkaus diffraction phenomenon, thiab zoo heev directionality, uas tso cai rau lawv mus kis tau raws li cov directional rays. Ultrasonic waves muaj peev xwm nkag mus rau hauv cov kua thiab cov khoom khov, tshwj xeeb tshaj yog nyob rau hauv cov khoom khov opaque. Thaum ultrasonic waves ntsib impurities lossis interfaces, lawv tsim cov reflections tseem ceeb hauv daim ntawv ntawm echo signals. Tsis tas li ntawd, thaum ultrasonic waves ntsib cov khoom txav mus los, lawv tuaj yeem tsim Doppler effects.

Hauv kev siv hauv kev lag luam, cov ultrasonic sensors paub txog lawv qhov kev ntseeg siab thiab muaj zog versatility. Cov txheej txheem ntsuas ntawm ultrasonic sensors ua haujlwm tau zoo nyob rau hauv yuav luag txhua qhov xwm txheej, ua rau muaj kev kuaj pom cov khoom lossis ntsuas qib khoom siv nrog qhov tseeb millimeter, txawm tias rau cov haujlwm nyuaj.

Cov cheeb tsam no suav nrog:

>Kev Tsim Kho Tshuab/Cov Cuab Yeej Siv Tshuab

>Khoom noj thiab dej haus

>Kev Ua Ntoo thiab Rooj Tog

>Cov Khoom Siv Hauv Tsev

Piv nrog rau lub sensor inductive thiab capacitive proximity sensor, lub ultrasonic sensor muaj qhov ntev dua rau kev ntes. Piv nrog rau lub sensor photoelectric, lub ultrasonic sensor siv tau rau hauv qhov chaw nyuaj dua, thiab tsis cuam tshuam los ntawm xim ntawm cov khoom, hmoov av lossis dej hauv huab cua. Lub ultrasonic sensor tsim nyog rau kev ntes cov khoom hauv ntau yam xwm txheej, xws li kua, cov khoom pob tshab, cov khoom siv reflective thiab cov khoom me me, thiab lwm yam. Cov khoom pob tshab xws li lub raj mis iav, phaj iav, zaj duab xis PP / PE / PET pob tshab thiab lwm yam khoom siv ntes. Cov khoom siv reflective xws li ntawv ci kub, nyiaj thiab lwm yam khoom siv ntes, rau cov khoom no, lub ultrasonic sensor tuaj yeem qhia tau zoo heev thiab ruaj khov ntes peev xwm. Lub ultrasonic sensor kuj tseem siv tau los ntes zaub mov, tswj cov khoom siv tsis siv neeg; Tsis tas li ntawd, kev tswj cov thee, ntoo chips, cement thiab lwm yam hmoov kuj tsim nyog heev.

Cov yam ntxwv ntawm cov khoom

> NPN lossis PNP hloov pauv tso zis
> Cov zis hluav taws xob analog 0-5 / 10V lossis cov zis tam sim no analog 4-20mA
> Cov zis TTL digital
> Cov zis tuaj yeem hloov pauv los ntawm kev hloov kho qhov chaw nres nkoj serial
> Teem qhov deb ntawm kev kuaj pom los ntawm cov kab qhia
> Kev them nyiaj kub

Diffuse reflection hom ultrasonic sensor

Kev siv cov ultrasonic sensors uas muaj kev cuam tshuam diffuse reflection yog dav heev. Ib lub ultrasonic sensor siv ua ob qho tib si ua emitter thiab receiver. Thaum lub ultrasonic sensor xa tawm ib lub beam ntawm ultrasonic waves, nws tso tawm cov suab waves los ntawm lub transmitter hauv lub sensor. Cov suab waves no kis mus rau qee qhov zaus thiab wavelength. Thaum lawv ntsib ib qho kev cuam tshuam, cov suab waves raug cuam tshuam thiab rov qab mus rau lub sensor. Thaum lub sijhawm no, lub receiver ntawm lub sensor tau txais cov suab waves thiab hloov lawv mus rau hauv cov teeb liab hluav taws xob.
Lub ntsuas qhov cuam tshuam ntawm lub suab ntsuas lub sijhawm uas cov nthwv dej suab siv los ntawm lub emitter mus rau lub receiver thiab xam qhov deb ntawm lub khoom thiab lub sensor raws li qhov ceev ntawm lub suab kis mus rau hauv huab cua. Los ntawm kev siv qhov deb ntsuas, peb tuaj yeem txiav txim siab cov ntaub ntawv xws li qhov chaw, qhov loj me, thiab cov duab ntawm lub khoom.

Ob chav ntawv ultrasonic sensor

Lub tshuab ntsuas ultrasonic ob daim ntawv siv lub hauv paus ntsiab lus ntawm lub tshuab ntsuas hom beam. Chiv thawj tsim los rau kev lag luam luam ntawv, lub tshuab ntsuas ultrasonic los ntawm beam siv los ntes qhov tuab ntawm daim ntawv lossis daim ntawv, thiab tuaj yeem siv rau lwm yam kev siv uas nws tsim nyog los sib txawv ntawm ib daim ntawv thiab ob daim ntawv kom tiv thaiv cov khoom siv thiab zam kev pov tseg. Lawv nyob hauv lub tsev me me nrog qhov ntau thiab tsawg ntawm kev ntes. Tsis zoo li cov qauv kev cuam tshuam diffuse thiab cov qauv kev cuam tshuam, cov tshuab ntsuas ultrasonic ob daim ntawv no tsis hloov pauv tas li ntawm hom kev xa thiab txais, thiab lawv tsis tos kom lub teeb liab echo tuaj txog. Yog li ntawd, nws lub sijhawm teb sai dua, ua rau muaj qhov zaus hloov pauv siab heev.

Nrog rau qib kev lag luam automation nce ntxiv, Shanghai Lanbao tau tsim ib hom ultrasonic sensor tshiab uas tuaj yeem siv rau hauv feem ntau cov xwm txheej kev lag luam. Cov sensors no tsis cuam tshuam los ntawm xim, glossiness, thiab pob tshab. Lawv tuaj yeem ua tiav kev tshawb pom khoom nrog millimeter qhov tseeb ntawm qhov luv luv, nrog rau kev tshawb pom khoom ultra-range. Lawv muaj nyob rau hauv M12, M18, thiab M30 installation threaded tes tsho, nrog kev daws teeb meem ntawm 0.17mm, 0.5mm, thiab 1mm feem. Cov hom tso zis suav nrog analog, hloov (NPN / PNP), nrog rau kev sib txuas lus interface tso zis.
