7-Step Guide Poyesa Sensor ya 3-Waya Pressure

Pakutha kwa nkhaniyi, mudziwa momwe mungayesere sensa yama waya atatu.

Kuyesa sensor ya 3-waya kumatha kukhala kovuta. Pamapeto pake, muyenera kuyang'ana mawaya onse atatu kuti akhale ndi magetsi. Mawaya awa ali ndi ma voltages osiyanasiyana. Chifukwa chake, popanda kumvetsetsa ndi kuphedwa koyenera, mutha kutayika, ndichifukwa chake ndili pano kuti ndikuthandizeni!

Nthawi zambiri, kuyesa sensor ya 3-waya:

Khazikitsani ma multimeter kuti ayese muyeso wamagetsi.
Lumikizani kutsogolo kwakuda kwa ma multimeter ku terminal yoyipa ya batri.
Lumikizani kafukufuku wofiyira wa multimeter ku terminal yabwino ya batri ndikuwunika voteji (12-13 V).
Tembenuzani kiyi yoyatsira pa ON (osayambitsa injini).
Pezani sensor ya pressure.
Tsopano yang'anani zolumikizira zitatu za sensa yamawaya atatu ndi kafukufuku wofiyira wa multimeter ndikulemba zowerengerazo.
Malo amodzi ayenera kuwonetsa 5V ndipo enawo aziwonetsa 0.5V kapena kupitilira apo. Malo omaliza ayenera kuwonetsa 0V.

Kuti mumve zambiri, tsatirani zomwe zili pansipa.

Tisanayambe

Musanayambe ku gawo lothandiza, pali zinthu zingapo zomwe muyenera kuzidziwa.

Kumvetsetsa mawaya atatu mu sensa yokakamiza kungakuthandizeni kwambiri poyesa sensor. Ndiye tiyeni tiyambe ndi izi.

Pakati pa mawaya atatu, waya wina ndi waya wolozera ndipo winayo ndi waya wolumikizira. Chomaliza ndi waya wapansi. Iliyonse mwa mawayawa ili ndi mphamvu yosiyana. Nazi zina zambiri za ma voltages awo.

Waya wapansi ayenera kukhala 0V.
Waya wolozera uyenera kukhala ndi 5V.
Ngati injini yazimitsidwa, waya wolumikizira uyenera kukhala 0.5V kapena kupitilira apo.

Injini ikayatsidwa, waya wamakina amawonetsa mphamvu yayikulu (5 ndi pansi). Koma ndichita mayesowa popanda kuyambitsa injini. Izi zikutanthauza kuti magetsi ayenera kukhala 0.5 V. Ikhoza kukwera pang'ono.

Langizo tsikuli: Mawaya a sensor pressure amabwera m'mitundu yosiyanasiyana. Palibe mtundu weniweni wa mawaya a sensor awa.

Kodi Reverse Probing ndi chiyani?

Njira yomwe timagwiritsa ntchito poyesa izi imatchedwa reverse probing.

Kuyang'ana mphamvu ya chipangizo popanda kuchichotsa ku cholumikizira kumatchedwa reverse probing. Iyi ndi njira yabwino yoyesera kutsika kwa voteji ya sensor pressure pansi pa katundu.

Muchiwonetserochi, ndikuwonetsani momwe mungayesere sensa yamagalimoto yama waya atatu. Galimotoyi imabwera ndi mitundu yosiyanasiyana ya masensa a kupanikizika, monga zoyezera kuthamanga kwa mpweya, zoyezera kuthamanga kwa matayala, masensa absolute pressure, masensa a njanji yamafuta, ndi zina zotero. Mwachitsanzo, kachipangizo ka mpweya kamene kamazindikira kupanikizika kwa mumlengalenga. (3)

Sensa ya njanji yamafuta imayang'anira kuthamanga kwamafuta. Sensa iyi ili pamalo opezeka mosavuta mgalimoto yanu. Chifukwa chake 3-waya sensor iyi ndiye chisankho chabwino pa bukhuli. (2)

Khwerero 1 - Khazikitsani ma multimeter anu kukhala ma voltage mode

Choyamba, ikani ma multimeter kuti akhale osinthasintha. Sinthani kuyimba komwe kuli koyenera. Ma multimeter ena ali ndi kuthekera kwa autorange ndipo ena alibe. Ngati ndi choncho, ikani kutalika kwa 20V.

Gawo 2 - Lumikizani waya wakuda

Kenako gwirizanitsani kutsogolo kwakuda kwa multimeter ku terminal yoyipa ya batri. Waya wakuda uyenera kukhalabe pa terminal yoyipa mpaka mayesowa atatha. Mutha kugwiritsa ntchito kulumikizana uku ngati poyambira mayesowa.

Khwerero 3 - Yang'anani pansi

Kenako gwirizanitsani chowongolera chofiira cha multimeter ku terminal yabwino ya batri ndikuwona kuwerenga.

Kuwerenga kuyenera kukhala pamwamba pa 12-13V. Iyi ndi njira yabwino yowonera kukhazikika. Mukhozanso kuyang'ana mkhalidwe wa magetsi ndi sitepe iyi.

Khwerero 4 - Pezani 3-waya sensor

Sensa ya njanji yamafuta ili kutsogolo kwa njanji yamafuta.

Khwerero 5 - Tembenuzani kiyi yoyatsira pamalo ON

Tsopano lowetsani mgalimoto ndikutembenuza kiyi yoyatsira ku ON. Kumbukirani, musayambe injini.

Khwerero 6 - Onani mawaya atatu

Chifukwa mudagwiritsa ntchito njira yoyang'ana m'mbuyo, simungathe kumasula mawaya pa cholumikizira. Payenera kukhala mipata itatu kumbuyo kwa sensor. Mipata iyi imayimira mareferensi, ma sign, ndi mawaya apansi. Chifukwa chake, mutha kulumikiza waya wa multimeter kwa iwo.

Tengani njira yofiira ya multimeter ndikuyilumikiza ku cholumikizira 1.
Lembani mawerengedwe a multimeter.
Chitaninso chimodzimodzi ndi mipata iwiri yotsalayo.

Gwiritsani ntchito kopanira pamapepala kapena pini yotetezera polumikiza waya wofiyira ndi mipata itatu. Onetsetsani kuti paperclip kapena pin ndi conductive.

Khwerero 7 - Yang'anani zowerengera

Tsopano muyenera kukhala ndi zowerengera zitatu mu kope lanu. Ngati sensa ikugwira ntchito bwino, mupeza zowerengera zotsatirazi.

Kuwerenga kumodzi kuyenera kukhala 5V.
Kuwerenga kumodzi kuyenera kukhala 0.5V.
Kuwerenga kumodzi kuyenera kukhala 0V.

Gawo la 5V limalumikizidwa ndi waya wolozera. Cholumikizira cha 0.5V chimalumikizana ndi waya wolumikizira ndipo cholumikizira cha 0V chimalumikizana ndi waya wapansi.

Chifukwa chake, sensor yabwino yamawaya atatu iyenera kupereka zowerengera pamwambapa. Ngati izi sizichitika, mukuchita ndi sensor yolakwika.

Onani zina mwazolemba zathu pansipa.
