Ngenxa yezinga elingalingani lenzwa yokucindezela kwemoto emakethe njengamanje, singakhetha futhi sikhombe kanjani umsebenzi nekhwalithi yenzwa yokucindezela kwezimoto?Ake sikhulume ngamapharamitha wokusebenza wenzwa yokucindezela njengoba ngezansi:
Inzwa yokucindezela isho idivayisi ekwazi ukuzwa ingcindezi futhi iguqule ushintsho lwengcindezi lube okukhipha isignali kagesi.Iwuhlobo oluvame kakhulu lwenzwa emishinini ezenzakalelayo, kanye nesistimu yezinzwa emishinini yokulinganisa amandla azenzakalelayo.Ukusetshenziswa okufanele kwenzwa yokucindezela kufanele kuqala kuqonde imingcele yenzwa yokucindezela kwemoto.
ikakhulukazi amapharamitha we-Autopressure sensor kanje:
1, Isilinganiso sokulayisha senzwa yokucindezela:Iyunithi evamile Ibha, i-Mpa, njll. Uma ububanzi bokulinganisa bungu-10Bar, ububanzi bokulinganisa benzwa yibha engu-0-10 0-1.Mpa.
2, Ibanga lokushisa elisebenzayo libhekisela ebangeni lokushisa lapho imingcele yokusebenza yenzwa yokucindezela ingasetshenziswa ngaphandle kwezinguquko eziyingozi ezingapheli.
3, Ibanga lesinxephezelo sezinga lokushisa : ukuthi kulolu banga lokushisa, okukhiphayo okulinganiselwe kanye nebhalansi enguziro yenzwa kunxeshezelwa ngokuqinile, ukuze kungeqi ububanzi obushiwo.
4, Umphumela wezinga lokushisa ku-zero: Umthelela wezinga lokushisa elinguziro libhekisela ethonyeni lokushintsha kwezinga lokushisa endaweni eyiziro yenzwa yokucindezela.Ngokuvamile, ivezwa njengephesenti lokushintsha kokulingana okunguziro okubangelwa ukushintsha kwezinga lokushisa okungu-10℃ kokuphumayo okulinganiselwe, futhi iyunithi ithi: %FS/10℃.
5, ukuzwela Umphumela wezinga lokushisa uphumile: Ukukhukhuleka kwezinga lokushisa kubhekisela ekushintsheni kokuzwela kwenzwa yokucindezela okubangelwa ukushintsha kwezinga lokushisa elizungezile.Ngokuvamile, ivezwa njengephesenti lokukhishwa okulinganiselwe kokushintsha kokuzwela okubangelwa ukushintsha kwezinga lokushisa elingu-10℃, futhi iyunithi ithi: FS/10℃.
I-6, okukhiphayo okulinganiselwe: i-coefficient yesignali ephumayo yenzwa yokucindezela, iyunithi i-mV / V, i-1mV / V evamile, i-2mV / V, ukukhishwa okugcwele kwenzwa yokucindezela = ukusebenza kwe-voltage * ukuzwela, isibonelo: I-voltage yokusebenza 5VDC, ukuzwela 2mV/V, uhla oluphelele oluphumayo ngu-5V*2mV/V=10mV, njengenzwa yokucindezela uhla olugcwele lwe-10Bar, ukucindezela okugcwele okungu-10Bar, okukhiphayo ngu-10mV, ukucindezela kuka-5Bar ngu-5mV.
I-7, Umkhawulo Womthwalo Ophephile: Umkhawulo wokulayisha ophephile usho ukuthi ngeke ubangele umonakalo olimazayo kunzwa yokucindezela ngaphakathi kwalo mthwalo, kodwa awukwazi ukulayishwa ngokweqile isikhathi eside.
I-8: Ukulayisha ngokweqile: kubhekisela enanini elilinganiselwe lomthwalo wenzwa yokucindezela.
9. Ukungalandeli umugqa: I-linearity isho iphesenti lokuchezuka okukhulu phakathi kwejika lomugqa nelilinganisiwe lokukhuphuka komthwalo uma kuqhathaniswa nokuphumayo okulinganiselwe, okunqunywa inani eliphumayo lomthwalo ongenalutho nomthwalo olinganiselwe.Ngokombono, okukhiphayo kwenzwa kufanele kube kumugqa.Eqinisweni, akunjalo.I-nonlinearity ukuchezuka kwephesenti ukusuka kokulungile.Iyunithi engelona umugqa ithi: %FS, iphutha elingaqondile = ububanzi * obungaqondile, uma ububanzi bungu-10Bar futhi okungaqondile kungu-1%fs, iphutha elingaqondile lithi: 10Bar*1%=0.1Bar.
I-11: Ukuphindaphinda: iphutha libhekisela ekulayisheni okuphindaphindiwe kwenzwa kumthwalo olinganiselwe nokulayisha ngaphansi kwezimo ezifanayo zemvelo.Iphesenti lomehluko omkhulu phakathi kwevelu yokukhiphayo nokuphumayo okulinganiselwe endaweni yokulayisha efanayo ngesikhathi sokulayisha.
I-12: I-Hysteresis: ibhekisela ekulayishweni kancane kancane kwenzwa yokucindezela ukusuka ekungalayishweni ukuya kumthwalo olinganiselwe bese ukhulula kancane kancane.Umehluko omkhulu phakathi kokuphumayo okulayishiwe nokulayishiwe endaweni efanayo yokulayisha njengephesenti lokuphumayo okulinganiselwe.
I-13: I-voltage ye-Excitation: ibhekisela ku-voltage yokusebenza yenzwa yokucindezela, ngokuvamile engu-5-24VDC.
14:Ukumelana nokokufaka: kubhekisela enanini lokumelana elilinganiswa kusukela ekugcineni kokufaka kwenzwa yokucindezela (imigqa ebomvu nemnyama yezinzwa zengcindezi yezimoto) lapho ukuphela kokuphumayo kwesignali kuvuliwe futhi inzwa ingacindezelwe.
I-15: Ukumelana nomphumela: kubhekisela ekuphikiseni okukalwa kusukela ekuphumeni kwesignali lapho okokufaka kwenzwa yokucindezela kufushane futhi inzwa ingacindezelwa.
I-16: I-Impedance ye-insulation: ibhekisela enani le-DC impedance phakathi kwesekethe yenzwa yokucindezela kanye ne-elastomer.
I-17: I-Creep : ibhekisela kumaphesenti oshintsho ekuphumeni kwenzwa yokucindezela ngokuhamba kwesikhathi ekuphumeni okulinganiselwe, okuvame ukuba yi-30min, ngaphansi kwesimo sokuthi umthwalo uhlala ungashintshi futhi ezinye izimo zokuhlola zihlala zingashintshiwe.
18: Ibhalansi enguziro :Inani eliphumayo lenzwa yokucindezela njengephesenti lokuphumayo okulinganiselwe ku-excitation kagesi enconyiwe uma kulayishwa.Ngokombono, okukhiphayo kwenzwa yokucindezela kufanele kube yiziro uma kulayishwa.Eqinisweni, ukukhishwa kwenzwa yokucindezela akuyona i-zero uma ilayishwa.Kukhona ukuchezuka, futhi okukhiphayo okunguziro kuyiphesenti lokuchezuka.
Okungenhla ukubuka konke kwemingcele yenzwa yokucindezela kwemoto.Uma uneseluleko, sicela ukhululeke ukushiya amazwana, Ifektri yethu yenzwa yokucindezela ibheke ngabomvu ukusungula ubudlelwano obuzinzile nobunesikhathi eside bokusebenzisana nganoma yisiphi isikhathi.
