Kodi chojambulira ndi chiyani?

Machitidwe amakono ogwiritsa ntchito amagwiritsa ntchito masensa ambiri omwe amasiyana pamachitidwe ndi magwiridwe antchito. Chimodzi mwama sensa odziwika kwambiri omwe amagwiritsidwa ntchito m'malo ambiri (kuphatikiza magalimoto) ndi sensa yolowerera, ndipo tiziisamalira kwambiri.

Kodi chojambulira ndi chiyani?

Ndi mawonekedwe ake, sensa iyi ndi ya zida zosalumikizana. Mwanjira ina, sensa yolowerera siyenera kukhala pafupi ndi chinthu kuti izindikire komwe kuli mlengalenga.

Masensa opatsa chidwi amagwiritsidwa ntchito nthawi zambiri pakafunika kugwira ntchito ndi zinthu zachitsulo ndi zitsulo m'malo ovuta kugwira ntchito.

Kodi chojambulira chimagwira bwanji?

Chifukwa chakapangidwe kake mkati, sensa yoyeserera ili ndi mfundo zina zogwirira ntchito. Jenereta yapadera imagwiritsidwa ntchito pano, yomwe imapanga matalikidwe ena. Chitsulo kapena ferromagnetic ikalowa m'gawo la sensa, zimanjenjemera zimayamba kuwerengedwa ndikusinthidwa.

Tiyeni tisinthe zinthu momwe zimagwirira ntchito ...

Kuti ayambe kugwira ntchito, sensa imaperekedwa ndi mphamvu, zomwe zimapangitsa kuti maginito apangidwe. Mundawu, nawonso, umapanga mafunde okulira omwe amasintha matalikidwe azisudzo mu jenereta yoyendetsa.

Chotsatira chomaliza cha kutembenuka konseku ndichizindikiro chotulutsa chomwe chimatha kusiyanasiyana kutengera mtunda wapakati pa sensa yolowera ndi chinthu choyesera.

Chizindikiro chomwe chimachokera ku sensa ndi analog, yomwe imasinthidwa kukhala logic ndi chida chapadera chotchedwa choyambitsa.

Kodi ndi zinthu ziti zomwe zimayandikira pafupi?

Zachidziwikire, pali mitundu yambiri yama sensa othandiza, koma ndi amodzi chifukwa ali ndi zinthu zazikuluzikulu:

Jenereta

Chofunikira kwambiri mu chipangizochi ndi jenereta, chifukwa imapanga gawo lamagetsi lomwe limathandizira kuzindikira ndikusanthula zinthu zachitsulo ndikuzindikira malo ake. Popanda jenereta ndi gawo lomwe limapanga, magwiridwe antchito a sensor yolowerera sangakhale otheka.

Chizindikiro chosinthira

Chinthuchi ndi chinthu ngati choyambitsa, ndipo ntchito yake ndikusintha chizindikiro kuti sensa igwirizane ndi zinthu zina zomwe zili mu dongosolo kuti zipitirize kufalitsa zambiri.

Mkuzamawu

Amplifier amafunika kuti siginecha yolandila ifike pamlingo woyenera wopatsirana.

Zizindikiro za LED

Zizindikiro za LED zikuwunika momwe kachipangizoka ikugwirira ntchito ndikuwonetsa kuti ilipo kapena kuti njira zingapo zowongolera zikuyenda.

Nyumba

Thupi lili ndi zonsezi pamwambapa

Mitundu yamasensa mumayendedwe amagalimoto komanso komwe kumagwiritsa ntchito sensa yolumikizira

Njira zowongolera zamagetsi zamagalimoto amakono sizingaganizidwe popanda masensa. Mitundu yosiyanasiyana yama sensa imagwiritsidwa ntchito pafupifupi pamakina onse agalimoto. Galimoto imayesa kutentha ndi kuthamanga kwa mpweya, mafuta, mafuta, ozizira.

Malo ndi ma sensa othamanga amaphatikizidwa ndi mbali zambiri zosunthika zamagalimoto monga crankshaft, distributor, throttle, shaft shaft, valve ya EGR, ndi zina zambiri. Kuphatikiza apo, masensa ambiri amagwiritsidwa ntchito pamakina otetezera magalimoto.

Kutengera ndi cholinga, masensa oyendetsa magalimoto agawika malo ndi masensa othamanga, masensa otulutsa mpweya, kuwongolera mpweya, kutentha, kuthamanga ndi ena.

Masensa opitilira muyeso amagwiritsidwa ntchito kwambiri kuyeza kuthamanga ndi malo azungulira mbali, koma zikuwoneka kuti kugwiritsidwa ntchito kwakukulu kwa sensa yamtunduwu ndikupeza malo ndi kuthamanga kwa crankshaft ya injini.

Popeza masensa osunthika ndi odalirika kwambiri, makamaka akagwira ntchito m'malo ovuta, amagwiritsidwa ntchito kwambiri osati m'makampani opanga magalimoto, komanso munkhondo, njanji, malo ndi mafakitale olemera.

Kodi ndi chiyani china chomwe tikufunikira kudziwa pokhudzidwa?

Malo ochititsa chidwi ndi sensa yothamanga ndi chipangizo chokhala ndi zenizeni zake, chifukwa chake, pofotokoza momwe ntchito yake imagwirira ntchito, matanthauzo apadera amagwiritsidwa ntchito, monga:

Malo ogwirira ntchito

Malo amenewa amatanthauza dera lomwe maginito amatchulidwadi. Pakatikati pake pali kutsogolo kwa malo obisika a sensa komwe kuli maginito apamwamba kwambiri.

Mwadzina kusintha mtunda

Chizindikiro ichi chimawerengedwa kuti ndi chongopeka chifukwa sichimaganizira za kapangidwe kake, kutentha kwake, kuchuluka kwamagetsi, ndi zina.

Ntchito zosiyanasiyana

Magwiridwe ake akuwonetsa magawo omwe amatsimikizira kugwira ntchito bwino komanso koyenera kwa sensa yoyeserera.

Kukonzekera

Kukonzekera kumakhudzana ndi zinthu zomwe zimapangidwa ndi chitsulo, zomwe zimayang'aniridwa ndi sensa.

Ubwino ndi zovuta zamasensa othandizira
Monga zida zina zonse, masensa olowerera ali ndi mphamvu zawo komanso zofooka zawo.

Mwa zazikulu kwambiri ubwino yamasensa amtunduwu ndi awa:

• Zambiri zomangamanga. Kapangidwe ka masensa othandizira kumakhala kosavuta kwambiri ndipo mulibe zinthu zovuta zomwe zimafunikira kasinthidwe kapadera. Chifukwa chake, masensa amakhala ndi mphamvu yayikulu komanso kudalirika, samasweka kawirikawiri, ndipo atha kugwiritsidwa ntchito kwa nthawi yayitali.

• ·Makhalidwe apadera - mawonekedwe a masensa opangira ma inductive amakulolani kuti muyike mosavuta ndikulumikiza magawo ena amagalimoto.

• · Sensitivity - masensa amtunduwu ndi ovuta kwambiri, omwe amalola kuti agwiritsidwe ntchito pogwira ntchito ndi zitsulo zosiyanasiyana ndi zinthu.

Chokhachokha ndichakuti ndizotheka kuti masensa amatha kutengeka ndi zinthu zakunja panthawi yogwira ntchito, chifukwa chake ndikofunikira kupereka zinthu zoyenera zomwe sizingasokoneze magwiridwe antchito a masensa olowera.

Kodi muyenera kumvetsera chiyani mukamasankha masensa othandizira?

Fomu

Masensa ochititsa chidwi amapezeka m'mawonekedwe osiyanasiyana, koma chofala kwambiri ndi mawonekedwe a cylindrical okhala ndi ulusi wothamanga kutalika kwa sensa. Chingwe chokhazikika cha ulusi ndi M 5, M 8, M 12, M 18 ndi M 30.

Kusintha mtunda

Zimatengera mawonekedwe enieni a jenereta, omwe amakhudzidwa ndi mafunde a eddy a malo oyezera. Kutalika kumasiyanasiyana kuchokera 1 mm. mpaka 25-30 mm. kutengera wopanga.

SENSOR mtundu

Nthawi zambiri masensa ndi analogi (1-10V, 4-20mA) ndi digito. Zotsirizirazi, nazonso, zimagawidwa mumtundu wa PNP ndi mtundu wa NPN. Kuphatikiza apo, ndikofunikira kudziwa ngati sensor ili ndi chinthu chotseguka (NO) kapena chotsekedwa (NC).

Waya

Nthawi zambiri chimagwiritsidwa ntchito ndi zingwe ziwiri kapena zingwe, koma sensa imatha kulumikizidwa ndi cholumikizira.

Mafunso ndi Mayankho:

Mfundo zoyendetsera ntchito ndi ma inductive sensors ndi ziti? Masensa oterewa amagwira ntchito potengera kusintha kwa maginito mu koyilo pomwe chinthu chachitsulo chimalowa m'dera la maginito. Chitsanzo chili mu oscilloscopes, ammeters, ngakhale mukutsuka galimoto.

Kodi ma induction sensors amagwira ntchito bwanji? Amayesa kukula kwa mphamvu ya electromotive ya induction. Pamene panopa ikuyenda mu coil ya sensa, ndipo chinthu chachitsulo chimadutsa pafupi ndi icho, chimasintha mphamvu ya maginito, ndipo sensor imazindikira kukhalapo kwa chinthu ichi.

Kodi mitundu ya masensa inductive ndi iti? Kulimbana ndi kupanikizika kwakukulu, waya wawiri, zitsulo zonse, zosagwira kutentha, maginito osagwira ntchito, umboni wa kuphulika, annular, tubular ndi standard.
