Injini Yezimoto Engizinjini I-Fuel Common Rail Pressure Pressure Swing Sensor 1875784C92

1.princapt of Operation

Umgomo osebenzayo we-Metal Resistance strain gauge yinto into evimbela ukumelana ama-adslorbed ezintweni ezisetshenziswayo ngezinto ezibonakalayo ngokuguqulwa kwemishini, eyaziwa ngokuthi yimisebenzi yokumelana. Inani lokumelana lomqhubi wensimbi lingavezwa yifomula elandelayo:

R = ρ

Lapho: ρ-ukuthula komqhubi wensimbi (ω / m)

S-- I-Cross-State Area of ​​Conductor ()

L-ud of conductor (m)

Ake sithathe ukumelana nobunzima bensimbi yensimbi njengesibonelo. Lapho ucingo lwensimbi lungaphansi kwamandla angaphandle, ubude bawo kanye nendawo yesigaba sesigaba izoshintsha. Kusuka kwifomula engenhla, kungabonakala kalula ukuthi inani layo lokumelana lizoshintsha. Uma ucingo lwensimbi lwelulwa ngamandla angaphandle, ubude baso buzokwanda futhi indawo yayo yesiphambano izokwehla, futhi inani layo lokumelana lizonyuka. Lapho ucingo lucindezelwa ngamandla angaphandle, ubude buyancipha futhi isigaba sesiphambano siyanda, futhi inani lokumelana liyancipha. Uma nje ushintsho lokumelana lukalwa (imvamisa ugesi ngaphesheya kokumelana ulinganiswa), isimo sokuluka kocingo lwe-strain lungatholwa.

Isicelo 2.Prince

Inzwa yokucindezela ye-corrosion-engavikeli ukuqina ayinakho ukudluliswa koketshezi, futhi ingcindezi isebenza ngqo endaweni yangaphambi kwe-ceramic diaphragm, okwenza i-diaphragm ichithwe kancane. Ukuphikiswa kwamafilimu okuwugqinsi kuphrintiwe endaweni engemuva kwe-ceraphragm ye-ceramic futhi kuxhumekile ukwakha ibhuloho le-wheatstone (ibhuloho elivaliwe). Ngenxa yomphumela we-piezoresorestive we-piezoresistor, ibhuloho lakha i-voltage voltage sinage yesiginali eqondile kakhulu ekucindezelweni futhi futhi okulingana ne-voltage. Isiginali esezingeni elijwayelekile silinganiselwe njengo-2.0 / 3.0 / 3.3 MV / V ngokusho kwamabanga okucindezela ahlukene. Ngokulinganisa ama-laser, inzwa inokuqina okushisa okuphezulu nesikhathi sokuqina. I-sensor inezinxephezelo zayo zokushisa ezingama-0 ~ 70 ℃ futhi ingaxhumana ngqo nabezindaba eziningi.

I-Ceramic iyinto eyaziwayo enobuhlakani obuphezulu, ukumelana nokugqwala, ukumelana nokugqoka, ukumelana nomthelela kanye nokumelana nokudlidliza. Ukuqina okushisayo kwama-ceramics kanye nokumelana kwayo okuwugqinsi kungenza izinga lokushisa lakhona liphezulu liphakeme njenge-40 ~ 135 ℃, futhi linokunemba okuphezulu nokuqina ekulinganiseni. I-Electrical Insulation degree> 2KV, isinali eqinile yokukhipha nokuqina okuhle kwesikhathi eside. Izinzwa ze-Ceramic ezinezimpawu eziphakeme kanye nentengo ephansi kuzoba ukuqondiswa kwentuthuko yezinzwa zengcindezi. EYurophu naseMelika, kukhona umkhuba wokubuyisela ngokuphelele ezinye izinhlobo zezinzwa. E-China, abasebenzisi abaningi ngokwengeziwe basebenzisa izinzwa ze-ceramic ukuthi zithathe imivimbo esetshenzisiwe ye-silicon pressure.
