Sensa ya ultrasonic ndi sensa yomwe imasintha ma ultrasound wave signals kukhala ma signals ena amphamvu, nthawi zambiri ma signals amagetsi. Ma ultrasonic wave ndi ma mechanical wave omwe ali ndi ma vibration frequency apamwamba kuposa 20kHz. Ali ndi makhalidwe a high frequency, short wavelength, minimal diffraction phenomenon, komanso directionality yabwino kwambiri, zomwe zimawalola kufalikira ngati directional ray. Ma ultrasonic wave amatha kulowa mu zamadzimadzi ndi zolimba, makamaka mu opaque solids. Pamene ma ultrasonic wave akukumana ndi zosafunika kapena interfaces, amapanga reflections zazikulu mu mawonekedwe a echo signals. Kuphatikiza apo, pamene ma ultrasonic wave akukumana ndi zinthu zoyenda, amatha kupanga Doppler effects.
Mu mafakitale, masensa a ultrasonic amadziwika kuti ndi odalirika kwambiri komanso osinthasintha kwambiri. Njira zoyezera masensa a ultrasound zimagwira ntchito modalirika pazochitika zonse, zomwe zimathandiza kuzindikira bwino chinthu kapena kuyeza mulingo wazinthu molondola, ngakhale pa ntchito zovuta.
Madera awa akuphatikizapo:
>Uinjiniya wa Makina/Zida za Makina
> Chakudya ndi Zakumwa
> Ukalipentala ndi Mipando
> Zipangizo Zomangira
> Ulimi
> Zomangamanga
> Makampani Opanga Mapepala ndi Mapepala
> Makampani Ogulitsa Zinthu
> Muyeso wa Mulingo
Poyerekeza ndi sensor yopangira zinthu ndi sensor yoyandikira capacitive, masensa a ultrasonic ali ndi nthawi yayitali yozindikira. Poyerekeza ndi sensor ya photoelectric, sensor ya ultrasonic ingagwiritsidwe ntchito m'malo ovuta, ndipo sikhudzidwa ndi mtundu wa zinthu zomwe zikufunidwa, fumbi kapena chifunga cha madzi mumlengalenga. Sensa ya ultrasonic ndi yoyenera kuzindikira zinthu m'magawo osiyanasiyana, monga zakumwa, zinthu zowonekera, zinthu zowunikira ndi tinthu tating'onoting'ono, ndi zina zotero. Zipangizo zowonekera monga mabotolo agalasi, mbale zagalasi, filimu yowonekera ya PP/PE/PET ndi zina zozindikira zinthu. Zipangizo zowunikira monga zojambula zagolide, siliva ndi zina zozindikira zinthu, pazinthu izi, sensor ya ultrasonic imatha kuwonetsa luso labwino komanso lokhazikika lozindikira. Sensa ya ultrasonic ingagwiritsidwenso ntchito kuzindikira chakudya, kuwongolera zokha mulingo wa zinthu; Kuphatikiza apo, kuwongolera zokha kwa malasha, matabwa, simenti ndi milingo ina ya ufa ndikoyeneranso kwambiri.

Sensa ya ultrasonic yowunikira mtundu wa kufalikira
Kugwiritsa ntchito masensa owunikira owunikira owonetsa kuwala ndi kwakukulu kwambiri. Sensa imodzi ya ultrasound imagwiritsidwa ntchito ngati chotulutsira komanso cholandirira. Sensa ya ultrasound ikatumiza kuwala kwa mafunde a ultrasound, imatulutsa mafunde a phokoso kudzera mu chotumizira chomwe chili mu sensa. Mafunde a phokoso awa amafalikira pa ma frequency ndi ma wavelength enaake. Akakumana ndi chopinga, mafunde a phokoso amawunikiridwa ndikubwezedwa ku sensa. Pa nthawiyi, wolandila wa sensa amalandira mafunde a phokoso owunikiridwa ndikuwasintha kukhala zizindikiro zamagetsi.
Sensa yowunikira yofalikira imayesa nthawi yomwe mafunde amawu amayenda kuchokera ku emitter kupita ku wolandila ndipo imawerengera mtunda pakati pa chinthucho ndi sensa kutengera liwiro la kufalikira kwa mawu mumlengalenga. Pogwiritsa ntchito mtunda woyezedwa, titha kudziwa zambiri monga malo, kukula, ndi mawonekedwe a chinthucho.

Sensa ya ultrasonic ya pepala lawiri
Sensa ya ultrasound ya pepala lawiri imagwiritsa ntchito mfundo ya sensa ya mtundu wa beam. Poyamba idapangidwira makampani osindikiza, sensa ya ultrasound ya beam imagwiritsidwa ntchito kuzindikira makulidwe a pepala kapena pepala, ndipo ingagwiritsidwe ntchito pazinthu zina pomwe ndikofunikira kusiyanitsa zokha pakati pa mapepala amodzi ndi awiri kuti muteteze zida ndikupewa kutayika. Amasungidwa m'nyumba yaying'ono yokhala ndi malo ambiri ozindikira. Mosiyana ndi ma diffuse reflection models ndi ma reflector models, ma doule sheet ultrasonic sensors awa samasinthana nthawi zonse pakati pa ma transmit ndi receiver modes, komanso sayembekezera kuti chizindikiro cha echo chifike. Zotsatira zake, nthawi yake yoyankhira imakhala yachangu kwambiri, zomwe zimapangitsa kuti pakhale kusintha kwakukulu.
Ndi kuchuluka kwa makina odziyimira pawokha m'mafakitale, Shanghai Lanbao yayambitsa mtundu watsopano wa sensa ya ultrasonic yomwe ingagwiritsidwe ntchito m'mafakitale ambiri. Masensawa sakhudzidwa ndi mtundu, kunyezimira, ndi kuwonekera bwino. Amatha kuzindikira chinthu molondola kwambiri pa mtunda waufupi, komanso kuzindikira chinthu mosiyanasiyana. Amapezeka mu M12, M18, ndi M30, yokhala ndi ma resolution a 0.17mm, 0.5mm, ndi 1mm motsatana. Mitundu yotulutsa ikuphatikizapo analog, switch (NPN/PNP), komanso kutulutsa kwa mawonekedwe olumikizirana.
