Iyini inzwa yengcindezi yomoya ehlukile?

Inzwa yengcindezi ehlukile iyidivayisi eliqapha ushintsho lwengcindezi yendawo ezikhundleni ezimbili ezihlukene. (Isibonelo, ingcindezi yamanzi aluhlaza ngaphambi kokuhlunga izoba phezulu kunaleyo ngemuva kokuhlunga. Lapho ingcindezi yamanzi ohlangothini lwengcindezi ephansi ikhuphuka ngokuzumayo, imvamisa kusho ukuthi isihlungi sivaliwe noma silimale.

Nge-Abakhiqizi bokudlulisa ingcindezi, Ukuphela kwengcindezi enhle nokubi kwehlukaniswa yi-diaphragm yensimbi engagqwali, ngakho-ke womabili amakamelo okucindezela ayatholakala kuketshezi lwamakhemikhali olunolaka, futhi ingcindezi yokuhlukanisa elilinganisiwe idluliselwa kwi-silicon wafer ngokusebenzisa i-diaphragm yokuhlukanisa kanye namafutha agcwalisiwe e-silicone, ukukhiqiza isiginali yamanje kagesi esezingeni le-mileampere, Okuqoqwa yinzwa ebucayi yengcindezi nebhodi yesekethe elandelwa isinxephezelo sokushisa ukufeza ukulinganisa okunembile kwe- ingcindezi yokwehluka.

Izingcindezi ezithola i-silicon ziguqulwa zaba amasiginali kagesi, bese okukhiphayo kusetshenziswa futhi kuhlelwe yibhuloho le-Wheatstone kanye nebhodi kagesi. Njengoba isignali eyisisekelo ye-mileampere ingakwazi ukudluliselwa ebangeni elide, futhi inzwa yengcindezi yomoya ehlukile ayikwazi ukufakwa eduze kwemishini ngokuphazamiseka okunamandla kagesi, okwenza ukufakwa kwayo kukhawulelwe kakhulu.

Imisebenzi yenzwa yengcindezi yohlukile

Izinzwa zokucindezela ezehlukile zisebenza ngokusebenza futhi ezivelele kakhulu ukukala umehluko wengcindezi phakathi kwamaphoyinti amabili okulinganisa .. Lo mehluko wengcindezi unemisebenzi eminingi. Isibonelo, i-siliconInzwa yengcindezi ehlukile hvacIngabona ushintsho kwengcindezi yomoya ohlelweni lwe-HVAC, futhi umehluko wengcindezi ye-silicon ogcwele uwoyela ungabona uketshezi olungenamfucumfucu futhi olungapheli, njengamanzi aluhlaza noma imidiya yomoya.

Iyini umdlulisi wengcindezi ohlukile?

I-Inzwa yengcindezi ye- hvacIfana nesiguquli esilinganisa isignali yokukhipha yenzwa ibe yisiginali engabonakala isilawuli esikude noma i-PLC Isoftware yekhompyutha (noma iguqula okokufaka okungekho kagesi kusuka ku-senzo kube yisiginali kagesi futhi kwandisa umthombo wesiginali wesilinganiso esikude nokulawula) Ukufeza ukuguqulwa kwesiginali, Ukusetshenziswa kwezinxephezelo zokushisa okuningana kuyadingeka.

Umehluko phakathi kwenzwa yengcindezi yomoya ehlukile kanye nokudlulisa ingcindezi yokuhluka

Umehluko oyinhloko ukunemba. Ukunemba kwenzwa yengcindezi yomoya ehlukile kuvame ukuba ngu-0.25% FS ~ 1% FS, futhi ukunemba kokudlulisa kwengcindezi yokuhluka kungu-0.05% FS ~ 0.075% FS. Ukukhiqizwa kwamanjeLEFOOLuhlobo lokudlulisa ingcindezi ehlukile kwezinga lokunemba ezingama-0.075% zamaphrojekthi ezenzakalelayo ezimboni.

Umehluko oyisisekelo ukuthi inzwa yengcindezi ehlukile iguqula kuphela ubuningi bomzimba obungewona ugesi njengezinga lokushisa, ingcindezi, Ingcindezi yomoya, kanye nengcindezi ye-hydraulic kumasiginali kagesi ayisisekelo abuthakathaka. Ngenkathi umdlulisi wengcindezi owehlukile kuyithuluzi elithuthukisa futhi liguqule amasiginali kagesi ayinhloko abe ngugesi osezingeni eliphakeme izimpawu. Ama-protocol wokudlulisa ahlukile adinga izidlulisi ezahlukahlukene. Ngamanye amagama, isidlulisi sokucindezela ukhulisa isignali kagesi ebuthakathaka eqoqwe yinzwa ibe yisiginali yezinga eliphakeme yokudluliswa kwebanga elide noma umthetho olandelwayo wedijithali. Ngaphezu kwalokho, isidlulisi sokucindezela okuhlukile singaguqula ukufaka okungekho kagesi kusuka kusenzwa kube yisiginali kagesi ngenkathi kukhulisisa Isilinganiso esikude nokulawula futhi singaguqula inani elilingisiwe libe yidijithali ngokwezidingo zamakhasimende.
