Ib qho ultrasonic sensor yog ib tug sensor uas hloov ultrasonic yoj signals mus rau lwm yam zog signals, feem ntau yog hluav taws xob teeb liab. Ultrasonic nthwv dej yog cov tshuab tsis muaj zog nrog kev co zaus siab dua 20kHz. Lawv muaj cov yam ntxwv ntawm qhov siab zaus, luv wavelength, qhov tshwm sim me me ntawm qhov sib txawv, thiab cov kev taw qhia zoo heev, tso cai rau lawv nthuav tawm raws li cov kab hluav taws xob. Ultrasonic tsis muaj peev xwm nkag mus rau cov kua thiab cov khib nyiab, tshwj xeeb tshaj yog nyob rau hauv cov khoom opaque. Thaum ultrasonic nthwv dej ntsib impurities lossis cuam tshuam, lawv tsim cov kev xav tseem ceeb hauv daim ntawv ntawm ncha teeb liab. Tsis tas li ntawd, thaum ultrasonic tsis ntsib cov khoom txav, lawv tuaj yeem tsim cov teebmeem Doppler.
Hauv kev lag luam, ultrasonic sensors paub txog lawv cov kev ntseeg siab thiab muaj zog versatility. Cov kev ntsuas ntawm ultrasonic sensors ua haujlwm ntseeg tau nyob rau hauv yuav luag txhua yam kev mob, ua kom pom tseeb cov khoom los yog ntsuas cov khoom ntsuas nrog millimeter raug, txawm tias ua haujlwm nyuaj.
Cov cheeb tsam no suav nrog:
> Mechanical Engineering/Machine Tools
> Khoom noj thiab dej haus
> Cov kws kho mob thiab cov rooj tog zaum
> Khoom siv tsev
> Ua liaj ua teb

Nyob rau hauv kev sib piv nrog inductive sensor thiab capacitive sib thooj sensor, ultrasonic sensors muaj ib tug ntev nrhiav tau ntau yam. Piv nrog rau photoelectric sensor, ultrasonic sensor yuav siv tau nyob rau hauv hnyav ib puag ncig, thiab tsis affated los ntawm cov xim ntawm lub hom phiaj cov khoom, cov plua plav los yog dej pos huab nyob rau hauv cov huab cua.Ultrasonic sensor yog tsim rau kev soj ntsuam cov khoom nyob rau hauv txawv xeev, xws li kua, Cov ntaub ntawv pob tshab, cov ntaub ntawv muaj kev cuam tshuam thiab cov khoom siv, thiab lwm yam. Cov ntaub ntawv pob tshab xws li iav fwj, iav daim hlau, pob tshab PP / PE / PET zaj duab xis thiab lwm yam ntaub ntawv tshawb nrhiav. Reflective cov ntaub ntawv xws li kub ntawv nyiaj, nyiaj thiab lwm yam ntaub ntawv nrhiav kom tau, rau cov khoom no, ultrasonic sensor yuav qhia tau zoo heev thiab ruaj khov muaj peev xwm. Tsis tas li ntawd, kev tswj tsis siv neeg ntawm cov thee, ntoo chips, cement thiab lwm cov hmoov qib kuj tseem tsim nyog.

Diffuse reflection hom ultrasonic sensor
Daim ntawv thov ntawm diffuse reflection ultrasonic sensors yog dav heev. Ib qho ultrasonic sensor yog siv los ua ob qho tib si emitter thiab receiver. Thaum lub ultrasonic sensor xa tawm ib tug nqaj ntawm ultrasonic tsis, nws emits lub suab tsis dhau lub transmitter nyob rau hauv lub sensor. Cov suab nthwv dej no nthuav tawm ntawm qee zaus thiab wavelength. Thaum lawv ntsib ib qho teeb meem, lub suab nthwv dej tau tshwm sim thiab rov qab mus rau lub sensor. Nyob rau lub sijhawm no, lub receiver ntawm lub sensor tau txais lub suab tsis muaj suab nrov thiab hloov mus rau hauv cov teeb liab hluav taws xob.
Lub diffuse reflection sensor ntsuas lub sij hawm nws siv rau lub suab nthwv dej los ntawm lub emitter mus rau lub receiver thiab xam qhov kev ncua deb ntawm cov khoom thiab lub sensor raws li qhov ceev ntawm suab propagation nyob rau hauv cov huab cua. Los ntawm kev siv qhov ntsuas qhov deb, peb tuaj yeem txiav txim siab cov ntaub ntawv xws li txoj haujlwm, qhov loj, thiab cov duab ntawm cov khoom.

Ob chav ntawv ultrasonic sensor
Ob daim ntawv ultrasonic sensor txais lub hauv paus ntsiab lus ntawm los ntawm beam hom sensor. Ameslikas tsim rau kev lag luam luam ntawv, ultrasonic los ntawm beam sensor yog siv los kuaj xyuas cov tuab ntawm daim ntawv lossis daim ntawv, thiab tuaj yeem siv rau hauv lwm daim ntawv thov uas yuav tsum tau txiav qhov txawv ntawm ib thiab ob daim ntawv los tiv thaiv cov khoom thiab tsis txhob pov tseg. Lawv nyob rau hauv ib tug compact vaj tse nrog ib tug loj nrhiav kom tau ntau yam. Tsis zoo li diffuse reflection qauv thiab cov qauv reflector, cov doule daim ntawv ultrasonic sensors tsis tu ncua hloov ntawm kis tau tus mob thiab txais hom, los yog lawv tsis tos rau lub ncha teeb liab los txog. Yog li ntawd, nws lub sij hawm teb sai dua, ua rau muaj kev hloov pauv ntau zaus.
Nrog kev nce qib ntawm kev lag luam automation, Shanghai Lanbao tau tshaj tawm ib hom tshiab ntawm ultrasonic sensor uas tuaj yeem siv rau hauv feem ntau cov xwm txheej. Cov sensors no tsis cuam tshuam los ntawm xim, glossiness, thiab pob tshab. Lawv tuaj yeem ua tiav cov khoom tshawb pom nrog qhov tseeb millimeter ntawm qhov luv luv, nrog rau kev tshawb pom cov khoom siv ultra-ntau. 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 zis hom muaj xws li analog, hloov (NPN / PNP), nrog rau kev sib txuas lus interface tso zis.
