I-Mercedes-Benz Air Conditioning Pressure Sensor 2038211592

Inzwa yokucindezela iyinzwa evame ukusetshenziswa kakhulu ekusebenzeni kwezimboni, esetshenziswa kabanzi ezindaweni ezahlukahlukene zokulawula okuzenzakalelayo ezimbonini, ezibandakanya ukongiwa kwamanzi kanye nokuphehlwa kwamanzi, ezokuthutha zikaloliwe, izakhiwo ezihlakaniphile, ukukhiqiza ukulawulwa okuzenzakalelayo, indiza, imboni yezempi, i-petrochemical, imithombo kawoyela, ugesi. amandla, imikhumbi, amathuluzi emishini, amapayipi kanye nezinye izimboni eziningi. Futhi ezindaweni ezahlukene, izinhlobo ezahlukene zezinzwa zokucindezela zidinga ukusetshenziswa ukuze kugwenywe amaphutha.

Izimiso zokusebenza zezinzwa zokucindezela ezahlukene

1. Inzwa yamandla e-piezoresistive: I-Resistance strain gauge ingenye yezingxenye eziyinhloko ze-piezoresistive strain sensor. Umgomo wokusebenza wegeji ye-metal resistance gauge into eyenza ukuthi ukumelana ne-strain kukhangiswe kusisekelo sezinto kushintsha ngokushintshashintsha komshini, okuvame ukwaziwa ngokuthi ukumelana ne-resistance effect.

2. Inzwa yokucindezela kwe-Ceramic: Inzwa yokucindezela kwe-ceramic isekelwe kumphumela we-piezoresistive, futhi ingcindezi isebenza ngokuqondile endaweni engaphambili ye-ceramic diaphragm, okuholela ekuguquguqukeni okuncane kwe-diaphragm. Izinqamuleli zefilimu eziwugqinsi ziphrintwa ngemuva kwe-ceramic diaphragm futhi zixhunywe ukwenza ibhuloho le-Wheatstone. Ngenxa yomphumela we-piezoresistive we-piezoresistive resistor, ibhuloho likhiqiza isignali ye-voltage eqondile kakhulu ngokulingana nengcindezi futhi iphinde ilingane ne-excitation voltage. Isignali ejwayelekile ilinganiswa njengo-2.0/3.0/3.3 mv/ngokuya ngobubanzi bengcindezi obuhlukahlukene.

3. Inzwa yokucindezela ye-silicon esabalele: Isimiso sokusebenza senzwa yokucindezela kwe-silicon ehlakazekile nayo isekelwe kumphumela we-piezoresistive. Ngokusebenzisa isimiso somphumela we-piezoresistive, ingcindezi yendawo elinganisiwe isebenza ngokuqondile ku-diaphragm (insimbi engagqwali noma i-ceramic) yenzwa, okubangela ukuthi i-diaphragm ikhiqize ukugudluka okuncane ngokulingana nokucindezela kwendawo, ukuze inani lokumelana izinguquko zenzwa. Lolu shintsho lutholwa yisekethe ye-elekthronikhi, futhi isignali yokulinganisa ejwayelekile ehambisana nalokhu kucindezela iyaguqulwa futhi ikhishwe.

4. Inzwa yokucindezela kwesafire: Ngokusekelwe kumgomo wokusebenza wokumelana nokucindezeleka, i-silicon-sapphire isetshenziswa njengento ebucayi ye-semiconductor, enezici zokulinganisa ezingenakuqhathaniswa. Ngakho-ke, inzwa ye-semiconductor eyenziwe nge-silicon-sapphire ayizwani nokushintsha kwezinga lokushisa futhi inezici ezinhle zokusebenza ngisho nasezingeni eliphezulu lokushisa. Isafire inokumelana okuqinile nemisebe; Ngaphezu kwalokho, inzwa ye-silicon-sapphire semiconductor ayinayo i-pn drift.

5. Inzwa yokucindezela kwe-Piezoelectric: Umphumela we-Piezoelectric yisimiso esiyinhloko sokusebenza kwenzwa ye-piezoelectric. Inzwa ye-Piezoelectric ayikwazi ukusetshenziselwa ukulinganisa okumile, ngoba ukushaja ngemva kwamandla angaphandle kugcinwa kuphela uma iluphu inomphumela ongapheli wokufaka. Lokhu akunjalo ekusebenzeni, ngakho-ke kunqunywa ukuthi inzwa ye-piezoelectric ingakala kuphela ukucindezeleka okuguquguqukayo.
