Maitiro ekuyedza Sensor yeImba ine Multimeter (Guide)

Kupera kwesimba, ruzha rukuru, uye kunzwa kuti injini yakavharwa neimwe nzira zviratidzo zvekuti uri kubata neakafa controller kana hall effect crank sensors mukati meinjini yako. 

Tevedza matanho aya kuti uedze iyo Hall effect sensor ine multimeter.

Kutanga, isa iyo DMM kuDC voltage (20 volts). Batanidza iyo nhema inotungamira yemultimeter kune nhema inotungamira yehoro sensor. Iyo dzvuku terminal inofanirwa kubatana kune yakanaka tsvuku waya yeHall sensor waya boka. Iwe unofanirwa kuwana kuverenga kwegumi nematatu volts paDMM. Ramba uchitarisa kubuda kwemamwe waya.

Iyo Hall sensor ndeye transducer inogadzira inobuda voltage mukupindura kune magineti. Muchikamu chino, iwe uchadzidza maitiro ekuyedza iyo Imba sensor ine multimeter.    

Chii chinoitika kana Hall masensa akatadza?

Kukundikana kweHoro sensors kunoreva kuti mutongi (bhodhi iro rinopa simba uye rinodzora mota) harina ruzivo rwakakosha runodiwa kuti unyatso wiriranisa simba remota. Iyo mota inofambiswa netambo nhatu (phase). Iwo matatu matanho anoda nguva yakakodzera kana mota inonamira, kupera simba uye kuita ruzha runogumbura.

Iwe unofungidzira here kuti masensa ako eHoro ane mhosva? Iwe unogona kuedza ne multimeter nekutevera aya matanho matatu.

1. Bvisa uye uchenese sensor

Nhanho yekutanga inosanganisira kubvisa sensor kubva pa cylinder block. Ngwarira tsvina, simbi machipisi nemafuta. Kana chimwe cheizvi chiripo, bvisa.

2. Camshaft sensor / crankshaft sensor nzvimbo

Ongorora injini schematic kuti uwane iyo camshaft sensor kana crankshaft chinzvimbo sensor mune yemagetsi control module (ECM) kana camshaft sensor. Wobva wabata imwe mugumo wewaya yejumper kune waya yechiratidzo uye imwe magumo kusvika kumuromo weiyo yakanaka probe. Iyo isina kunaka probe inofanirwa kubata yakanaka chassis pasi. Funga kushandisa crocodile clip jumper paunenge uchibatanidza nzira isina kunaka inotungamira kune chassis pasi - kana zvichidikanwa.

3. Kuverenga voltage pane digital multimeter

Wobva waisa iyo digital multimeter kuDC voltage (20 volts). Batanidza iyo nhema inotungamira yemultimeter kune nhema inotungamira yehoro sensor. Iyo dzvuku terminal inofanirwa kubatana kune yakanaka tsvuku waya yeHall sensor waya boka. Iwe unofanirwa kuwana kuverenga kwegumi nematatu volts paDMM.

Ramba uchitarisa kubuda kwemamwe waya.

Wobva wabatanidza waya yakasviba yemultimeter kune tambo yakasviba yewaya. Iyo tsvuku tsvuku ye multimeter inofanira kubata tambo yakasvibirira pane wiring harness. Tarisa kana voltage ichiratidza mashanu kana kupfuura volts. Ziva kuti voltage inoenderana nekuiswa kwedunhu uye inogona kusiyana kubva kune imwe mudziyo kuenda kune imwe. Nekudaro, inofanirwa kunge yakakura kupfuura zero volts kana maSensors eHoro ari OK.

Zvishoma nezvishoma fambisa magineti pamakona ekurudyi kuenda kumberi kweencoder. Tarisa kuti chii chiri kuitika. Sezvo iwe uchiswedera pedyo ne sensor, iyo voltage inofanira kuwedzera. Paunenge uchifamba, voltage inofanira kuderera. Yako crankshaft sensor kana kubatana kwayo kwakashata kana pasina shanduko mumagetsi.

Summing up

Masensa emuhoro anopa akawanda mabhenefiti akadai sekuvimbika kunodiwa zvakanyanya, kukurumidza kukurumidza kushanda, uye pre-yakarongwa magetsi ekubuda nemakona. Vashandisi vanoidawo nekuda kwekugona kwayo kushanda mumhando dzakasiyana dzetembiricha. Iwo anoshandiswa zvakanyanya mumotokari dzinofamba, otomatiki zvishandiso, zvemugungwa zvekubata, michina yekurima, yekucheka nekudzosera kumashure michina, uye kugadzirisa uye kurongedza michina.
