7-Nhanho Yekutungamira Yekuyedza 3-Waya Kudzvanya Sensor

Pakupera kwechinyorwa chino, iwe unozoziva maitiro ekuyedza matatu-waya pressure sensor.

Kuedza 3-waya pressure sensor inogona kuve yakaoma. Pakupedzisira, iwe uchafanirwa kutarisa ese mawaya matatu kune voltage. Waya idzi dzine magetsi akasiyana. Saka, pasina kunzwisisa kwakakodzera uye kuuraya, unogona kurasika, ndosaka ndiri pano kuti ndibatsire!

Kazhinji, kuyedza 3-waya pressure sensor:

Seta iyo multimeter kune voltage kuyerwa maitiro.
Batanidza iyo nhema inotungamira yemultimeter kune yakaipa bhatiri terminal.
Batanidza iyo tsvuku probe ye multimeter kune yakanaka terminal yebhatiri uye tarisa iyo voltage (12-13 V).
Shandura kiyi yekudzima kune ON chinzvimbo (usatange injini).
Tsvaga iyo pressure sensor.
Zvino tarisa matatu matatu ekubatanidza matatu-waya sensor ine tsvuku multimeter probe uye rekodha kuverenga.
Imwe slot inofanirwa kuratidza 5V uye imwe inofanirwa kuratidza 0.5V kana kukwira zvishoma. Iyo yekupedzisira slot inofanira kuratidza 0V.

Kuti uwane tsananguro yakadzama, tevera iyo post pazasi.

Tisati tatanga

Usati waenderera kune chikamu chinoshanda, pane zvinhu zvishoma zvaunofanira kuziva.

Kunzwisisa mawaya matatu mune yekumanikidza sensor kunogona kukubatsira zvakanyanya paunenge uchiyedza sensor. Saka ngatitange neizvi.

Pakati petambo nhatu, waya imwe ireferensi waya uye imwe yacho iwaya yechiratidzo. Yekupedzisira iwaya yepasi. Imwe neimwe yewaya idzi ine magetsi akasiyana. Heano mamwe mashoko pamusoro pemagetsi avo.

Waya yepasi inofanira kuva 0V.
Waya yereferensi inofanirwa kunge iine 5V.
Kana injini yakadzimwa, waya yechiratidzo inofanira kunge iri 0.5V kana kukwira zvishoma.

Kana injini ikavhurwa, waya yechiratidzo inoratidza simba rakakura (5 uye pazasi). Asi ini ndichaita bvunzo iyi ndisina kutanga injini. Izvi zvinoreva kuti magetsi anofanira kunge ari 0.5 V. Inogona kusimuka zvishoma.

Zano rezuva: Iyo yekumanikidza sensor waya inouya mumhando dzakasiyana musanganiswa. Iko hakuna chaiyo yemavara kodhi kune idzi sensor waya.

Chii chinonzi Reverse Probing?

Nzira yatinoshandisa mukuyedza iyi inonzi reverse probing.

Kutarisa ikozvino kwemudziyo usina kuubvisa kubva pachokubatanidza kunonzi reverse probing. Iyi inzira yakanaka yekuyedza kudonha kwevoltage yekumanikidza sensor pasi pemutoro.

Mune iyi demo, ini ndichafamba iwe kuburikidza maitiro ekuyedza matatu-waya mota yekumanikidza sensor. Mota iyi inouya nemhando dzakasiyana-siyana dzezvidziviriro zvepressure, zvakadai semasensa emhepo, tyre pressure sensors, absolute pressure sensors, fuel rail sensors, etc. Semuenzaniso, air pressure sensor inoona atmospheric pressure.(3)

7-Nhanho Yekutungamira Yekuyedza 3-Waya Kudzvanya Sensor

Iyo mafuta njanji sensor inotarisisa kudzvanywa kwemafuta. Iyi sensor iri munzvimbo inowanikwa zviri nyore mumotokari yako. Saka iyi 3-waya sensor ndiyo yakakwana sarudzo yegwaro iri. (2)

Nhanho 1 - Isa yako multimeter kune voltage mode

Kutanga, isa iyo multimeter kune inogara voltage mode. Tenderedza dial kunzvimbo yakakodzera. Mamwe mamultimeters ane autorange kugona uye mamwe haana. Kana zvakadaro, isa span ku20V.

Danho 2 - Batanidza waya nhema

Wobva wabatanidza iyo nhema inotungamira yemultimeter kune yakaipa terminal yebhatiri. Waya nhema inofanira kuramba iri pane negative terminal kusvika bvunzo iyi yapera. Unogona kushandisa chinongedzo ichi sechikonzero chebvunzo iyi.

Nhanho 3 - Tarisa pasi

Wobva wabatanidza iyo dzvuku lead ye multimeter kune yakanaka bhatiri terminal uye tarisa kuverenga.

Kuverenga kunofanira kuva pamusoro pe12-13V. Iyi inzira yakanaka yekutarisa grounding. Iwe unogona zvakare kutarisa mamiriro emagetsi ekupa nedanho iri.

Nhanho 4 - Tsvaga iyo 3-waya sensor

Iyo mafuta njanji sensor iri pamberi pechitima chemafuta.

Nhanho 5 - Shandura kiyi yekubatidza kune iyo ON chinzvimbo

Zvino pinda mumotokari uye shandura kiyi yekubatidza kune ON chinzvimbo. Yeuka, usatanga injini.

Danho 6 - Tarisa waya nhatu

Nekuda kwekuti wakashandisa reverse probing nzira, haugone kuburitsa waya kubva pane chinongedzo. Panofanira kunge paine matatu slots kumashure kwe sensor. Aya slots anomiririra referensi, chiratidzo, uye waya dzepasi. Saka, iwe unogona kubatanidza multimeter waya kwavari.

Tora mutungamiri mutsvuku we multimeter uye uibatanidze kune 1st connector.
Nyora pasi kuverenga kwemultimeter.
Ita zvakafanana kune mamwe maviri asara slots.

Shandisa pepa clip kana pini yekuchengetedza paunenge uchibatanidza waya tsvuku kune matatu slots. Ita shuwa kuti paperclip kana pini inofambisa.

Danho rechinomwe - Ongorora kuverenga

Iwe zvino unofanirwa kuve nekuverenga katatu mubhuku rako rekunyorera. Kana iyo sensor iri kushanda nemazvo, iwe unowana inotevera voltage kuverenga.

Kuverenga kumwe kunofanira kuva 5V.
Kuverenga kumwe kunofanira kuva 0.5V.
Kuverenga kumwe kunofanira kuva 0V.

Iyo 5V slot yakabatana nereferensi waya. Iyo 0.5V yekubatanidza inobatanidza newaya yechiratidzo uye chinongedzo che0V chinobatana newaya yepasi.

Nekudaro, yakanaka matatu-waya yekumanikidza sensor inofanirwa kupa izvo zviri pamusoro kuverenga. Kana izvi zvikasaitika, iwe uri kubata neine kukanganisa sensor.

Tarisa zvimwe zvezvinyorwa zvedu pazasi.
