Ambient tembiricha sensor BMW e39

Handina kunyora chero chinhu kwenguva yakareba, kunyange, kuva akatendeseka, paiva nenguva dzinofadza, asi, nhamo, handina kutora mifananidzo, handina kunyora.

Ini ndichasimudza dambudziko neiyo tembiricha sensor overboard BMW 65816905133 E38 E46 E87 E90. Musoro wacho wakavharwa uye kune ruzivo rwakawanda pairi, asi pane zvidiki nuances zvandinoda kunyora nezvazvo.

Solution yematambudziko.

1) Mukurongeka inoratidza -40 madhigirii

Saka sensor yakaputsika. Kana iyo sensor yakaiswa, saka iwe unofanirwa kutanga watarisa iyo ine multimeter. Kupokana kwe sensor inoshanda kunofanirwa kunge kuri munharaunda ye3-5 kOhm. Kana iyo multimeter ichiratidza kusingaperi kana yakanyanya kupikisa (mazana ekΩ), ipapo sensor haina kunaka uye inofanira kutsiviwa.

Zvadaro tarisa mamiriro ematare panzvimbo iyo chip yakabatanidzwa, waya dzinogona kunge dzakaputika kana kuputsika.

2) Kurongeka kwakaratidza +50 madhigirii.

Inoitika kana ipfupi yedunhu mumatambo anoenda kune sensor, kana pfupi dunhu mukati me sensor (yakajairika kesi kana uchishandisa Chinese sensors). Tarisa sensor ine multimeter uye kana kuramba kwayo kuri pedyo ne zero, unogona kuedza kumutsidzira iyi sensor. Kune dunhu diki rakadaro, sezvandakatonyora pama sensors echiChinese, nekuda kwekuti vanobatika vanogona kunyura mudzimba dze sensor. Tora mapikisi matete uye nekuedza kushoma dhonza vanobatika kunzvimbo yavo yepakutanga. Aya ndiwo maitiro andakaita zvakare sensor yakatumirwa kwandiri kubva kualiexpress. Pakutanga, yaishanda, asi mushure mekubatana kwakawanda kusina kubudirira, fuse yekuonana yakaputika.

3) Tidy inoratidza tembiricha isiriyo, yakaderera.

Izvi zvinoitika nekuda kwekuora kwewaya kana oxidation yema sensor contacts. Chenesa vanobatana pachipu netsono, uye zvakare tarisa waya. Dzorera chip kana zvichibvira. Iyo yekare chip inogona kutengeswa kune waya, chinhu chikuru ndechokuiparadzanisa nemazvo uye kuibatanidza zvakare.

Ndeipi sensor yekusarudza.

Iyo overboard tembiricha sensor ndeye yakajairwa uye yakachipa thermistor yakaumbwa mune yepurasitiki kesi, uye kana ekare ekutanga aive nemhangura kana yendarira tipi inobvumidza iwe kukurumidza kuendesa kupisa kune thermoelement, saka masensa matsva haana kunyanya kusiyana nekugadzirwa kweChinese, uyezve, handingashamisi kana mumotokari dzemotokari maChina sensors achatengeswa nemutengo wepakutanga. Bvumirana, inobatsira - ndakaitenga nedhora, uye ndakaitengesa 10. Naizvozvo, ini ndichapa akati wandei sarudzo dzekusarudza sensor.

• Unotenga thermistor pamusika weredhiyo.

Kana iwe uchida kuita izvi zvakachipa uye nekukurumidza sezvinobvira, ingotsvaga chero 4,7 kΩ thermistor muchitoro cheredhiyo. Iwe unogona kuverenga zvakawanda nezve thermistor pano. Kubatsira kukuru kwemhinduro iyi ndeyekuti haufanirwe kutsvaga machipisi kana usina (akachekwa nenyama). Uye zvakare, iyo dhizaini sarudzo yekuti ungaisa kupi iri kwauri, ichikubvumidza kuti uise iyo thermistor mune chero nzvimbo iri nyore, zvichireva kuti hauchadi kushandura sensor.

• Kutenga sensor yeChinese.

Sezvandatonyora, vanobatika dzimwe nguva vanowanikwa pane ma sensors, anotungamira kune +50 pamusoro. Chinhu chikuru apa ndechekuchiisa zvakanyatsonaka muchip. Iyo thermistor chikamu chakasimba, iyo sensor imba yakanaka kwazvo, asi maChinese haana kudzidza maitiro ekuita vanovimbika. Mune yangu, ndakasarudza mhinduro yakadaro, asi handina kuwana nzvimbo yekubatanidza sensor kune bumper. Naizvozvo, ndakaigadzirisa pane screed munzvimbo yakachengeteka ye sensor. Verified link kune aliexpress.

• Kutenga yekare yepakutanga.

Yaiva yepakutanga ine muromo wendarira kana wendarira. Paunenge uchitenga, iwe unofanirwa kutora multimeter kuti utarise sensor. Ini ndinofunga iwe hauzoona misiyano yakawanda neiyo aftermarket kana thermistor.

Zvakakosha! Kupokana kwe thermocouple kunoshanduka nekukurumidza. Zvakakwana kutora sensor muruoko rwako, sezvo inokurumidza kuchinja kuramba kwayo. Asi kuiswa mumotokari, nekuda kwechimwe chikonzero, iyo yakarongeka haidi kuratidza shanduko nekukurumidza uye zvine simba. Izvi zvingangove zvichikonzerwa nekuwanda kweongororo uye kuyedza kuverengera kuverenga kuitira kuti tembiricha isashanduke pese painopfuura nepamhepo yekudziya kana zvimwe zvinopisa. Saka, mushure mekuisa sensor, tembiricha ichave -40 madhigirii, uye iwe unofanirwa kumirira maawa 1-2 kusvika tembiricha yadzokera kune yakajairika.

Zvakakosha! Kana iwe uchityaira muzhizha nekudziya kwe -40 madhigirii, saka une magirazi anopisa uye washer nozzles nesimba rakazara. Izvi zvinogona kukuvadza maheater ezvinhu izvi! Zvakakosha kucherechedza kuti kupisa kwemagirazi uye nozzles kunoshandawo mumamiriro okunze anopisa. Pane imwe nzvimbo mubhuku rekushanda nekugadzirisa motokari pane ndiro inoratidza kuti kupisa kunoshanda kwenguva yakareba sei mune mamwe mazinga ekushisa Onawo: Gazelle 322132 technical specifications
