Ni irihe tandukaniro riri hagati y'igipimo cy'urwego rwa ultrasonic na gipimo cy'urwego rwa radar?

Urwego ni kimwe mu bipimo by'ingenzi by'ingenzi mu igenzura ry'imikorere y'inganda. Mu gupima buri gihe urwego rw'ibigega bitandukanye, silos, pisine, nibindi, biragoye kugira ibikoresho biri ku rwego bishobora kubahiriza imiterere yose y'akazi bitewe n'imiterere itandukanye y'ubutaka.

Muri byo, ibipimo bya radar na ultrasound bikoreshwa cyane mu bikoresho bipima bidahuza. None se, itandukaniro riri hagati ya meter y'urwego rwa radar n'icyuma gipima urwego rwa ultrasound ni irihe? Ihame ry'ubu bwoko bubiri bwo gupima ni irihe? Ni izihe nyungu za meter y'urwego rwa radar n'icyuma gipima urwego rwa ultrasound?

Ubwa mbere, igipimo cy'urwego rwa ultrasound

Muri rusange, urusaku rw'amajwi twita frequency irenga 20kHz, ultrasonic wave ni ubwoko bw'urusaku rw'amajwi, ni ukuvuga vibration ya mekanike mu buryo bwo gukwirakwira mu nzira yo gukwirakwira, irangwa n'frequency yo hejuru, uburebure bw'umurambararo bugufi, imiterere mito yo gukwirakwira, hamwe n'ubuyobozi bwiza, bishobora guhinduka imirasire n'icyerekezo.

Kugabanya imiterere ya Ultrasonic mu bintu bito n'ibikomeye ni bike cyane, bityo ubushobozi bwo kwinjira ni bwinshi, cyane cyane mu bintu bikomeye bidasobanutse neza, Ultrasonic ishobora kwinjira muri metero mirongo mu burebure, guhura n'imyanda cyangwa aho bihurira bizagira ishusho igaragara cyane, gupima urwego rwa Ultrasonic ni uburyo bwo gukoresha iyi mikorere.

Mu ikoranabuhanga ryo gupima ikoranabuhanga, uko ubwoko bwose bw'igikoresho cya ultrasound bwaba bumeze kose, ni ngombwa guhindura ingufu z'amashanyarazi mo imyuka ya ultrasound, hanyuma ukongera kwakira ibimenyetso by'amashanyarazi, igikoresho kugira ngo kirangize uyu murimo cyitwa ultrasonic transducer, kizwi kandi nka probe.

Iyo ikora, transducer ya ultrasonic ishyirwa hejuru y'ikintu cyapimwe hanyuma igasohora umuraba wa ultrasound hasi. Umuraba wa ultrasonic unyura mu kirere, ugaruka inyuma iyo uhuye n'ubuso bw'ikintu cyapimwe, hanyuma transducer ikakirwa na transducer igahinduka ikimenyetso cy'amashanyarazi. Nyuma yo kubona iki kimenyetso, igice cyo kumenya ikoranabuhanga kigihindura ikimenyetso cyo ku rwego rwo kwerekana no gusohora.

Kabiri, igipimo cy'urwego rwa radar

Uburyo bwo gukora bwa meter y’urwego rwa radar ni bumwe n’ubwo meter y’urwego rwa ultrasonic, kandi meter y’urwego rwa radar ikoresha uburyo bwo gukora bwo kohereza – gusubiza – kwakira. Itandukaniro ni uko gupima meter y’urwego rwa radar bishingiye ahanini kuri transducer ya ultrasonic, mu gihe meter y’urwego rwa radar ishingiye ku mutwe w’amajwi menshi na antene.

Ibipimo by'urwego rwa Ultrasonic bikoresha imiraba ya mekanike, mu gihe ibipimo by'urwego rwa radar bikoresha imiraba ya electromagnetic iri hejuru cyane (kuva kuri G kugeza kuri mirongo ya G Hertz). Imiraba ya electromagnetic igenda ku muvuduko w'urumuri, kandi igihe cy'urugendo gishobora guhindurwamo ikimenyetso cy'urwego hakoreshejwe ibice by'ikoranabuhanga.

Ikindi gipimo gisanzwe cya radar ni igipimo cy’urwego rwa radar y’umuraba uyobowe.

Igipimo cy’urwego rwa radar y’umuraba uyobowe ni igipimo cy’urwego rwa radar gishingiye ku ihame rya reflectometry y’umwanya (TDR). Ingufu za elegitoronike z’igipimo cy’urwego rwa radar zikwirakwira ku mugozi w’icyuma cyangwa probe ku muvuduko w’urumuri. Iyo zihuye n’ubuso bw’icyuma gipimwe, igice cy’ingufu za metero y’umuraba zigaragara kugira ngo zikore echo hanyuma zigasubira ku gikoresho cyo gutangiza pulse mu nzira imwe. Intera iri hagati y’icyuma gitanga amakuru n’ubuso bw’igice gipimwe ingana n’igihe cyo gukwirakwiza pulse aho uburebure bw’urwego rw’amazi bubarwa.

Icya gatatu, ibyiza n'ibibi bya radar na ultrasound level meter

1. Ubuhanga bwa Ultrasonic ntabwo ari bwiza nk'ubwa radar;

2. Bitewe n'isano iri hagati y'umuvuduko n'ingano ya antene, icyuma gipima urwego rwa radar gifite umuvuduko wo hejuru ni gito kandi cyoroshye gushyiramo;

3. Kubera ko umurongo wa radar uri hejuru, uburebure bw'umurambararo ni bugufi, kandi hari ishusho nziza ku buso bukomeye buhengamye;

4. Agace k'ubuhumyi gapima radar ni gato ugereranije n'agakoresho ka ultrasound;

5. Bitewe n'umuvuduko mwinshi wa radar, Inguni y'imirasire ya radar ni nto, ingufu ziba nyinshi, kandi ubushobozi bwo gusubira inyuma burushaho kwiyongera mu gihe bifasha kwirinda kubangamirana;

6. Ugereranyije n'ibipimo by'urwego rwa ultrasonic bikoresha imiraba ya mekanike, radar ntabwo ikorwaho n'umwuka uva mu kirere, umwuka w'amazi uri mu kirere, ivumbi (usibye grafiti, ferroalloy n'indi vumbi ryinshi rya dielectric), impinduka z'ubushyuhe n'umuvuduko;
