Ukuhlaziywa kwe-Zero Drift of Afferential Cimitter Transmitter

Table of Content [Hide]

Isidlulisi sokuhlukanisa kwengcindezi emincane silungele ukukala ingcindezi noma ingcindezi yokuhlukanisa engaphansi kwe-1000Pa. Inkinga yengcindezi emincane ye-zero drift izonikeza amaphutha angamukeleki kwisilinganiso. Kuleli phepha, sihlaziya izici ezisemqoka ezithonyayo ze-zero drift, khona izindlela nezinyathelo zokulungisa ukuxazulula ukudlulisa ingcindezi emincane yokuhlukanisa i-zero drift, futhi uqinisekise ukunemba kokulinganisa kokudlulisa ingcindezi emincane. I-Lefoo ingaba nezinhlobo zokudlulisa izingcindezi zokuhlukahlukaI-transducer yengcindezi yokuhlukanisa okuphansi, LFM11 uchungechunge lokudlulisa umfanekiso wengcindezi kanye no-LFM11Isidlulisi sokucindezela umehluko.

1. Iyini i-zero drift ye-micro pressure transmitter?

Ukukhuleka kwe-Zero kokudlulisa ingcindezi emincane yokuhlukanisa kubhekisa esimweni sokuthi okukhiphayo kuyashintsha ngesikhathi lapho ukufaka nokushisa okuzungezile Isidlulisi sokucindezela okuncane sihlala singashintshi. Kubangelwa ukushintsha kokushisa kwayo kwangaphakathi, futhi ukuguquguquka kwangaphakathi kwamanje namandla wenzwa kuholela ekungazinzi kokusebenza kwesixhumanisi esithile. I-Zero drift iyinkomba ekhombisa ukuzinza kokudlulisa kwengcindezi emincane.

Izinqubo nezinto zokudlulisa izingcindezi ezikhiqizwa ngabakhiqizi abahlukahlukene bokudlulisa ingcindezi zihlukile, futhi i-coefficient yokushisa zero drift nayo yehlukile, ehlobene ngqo nokushisa okuzungezile kokudlulisa ingcindezi emincane.

2. Izici eziholela ekukhukhulekeni okungu-zero kwe-micro ehlukanisayo yokudlulisa ingcindezi

Isidlulisi sokucindezela ngokuzinza okuhle sinezimo ezintathu: ushintsho lwamaphoyinti ayi-zero lwe-transmitter yengcindezi ebangelwe ingcindezi emile incane kakhulu noma cishe cha, ushintsho lwamaphoyinti ayi-zero lwe-transmitter yengcindezi ebangelwe ukucindezeleka okungapheli kuncane kakhulu, futhi ushintsho lwamaphoyinti ayi-zero lwe-transmitter yengcindezi ebangelwe ukushisa nomswakama kuncane kakhulu. Ukuzinza kokudluliswa kwengcindezi emincane yokuhlukanisa nakho kubonakala nge-zero-point drift.

Ukukhukhuleka kwe-zero kwe-microIsidlulisi sokucindezela okuhlukileOkubangelwe ngamadivayisi nezinqubo enqubweni yokukhiqiza ayikwazi ukushintshwa ngumsebenzisi, ngakho-ke ayinakwa lapha. Ku-transmitter yengcindezi emincane yokuhlukanisa efakwe esizeni sokusebenzisa, ukuhamba kwe-zero okubangelwa ukushintshwa kwezinga lokushisa kwesiza, Imodi yokufakwa, ukudlidliza kanye namandla okuphakela amandla kungukukhathazeka kochwepheshe bezinsimbi. Uhlelo lwezobuchwepheshe kanye nezinyathelo zokulungisa ukuxazulula ukuhamba kwe-zero kwe-micro ye-micressure pressure nayo yakhiwe ngokuya ngalezi zinto ..

Ukuze uthole idatha ethile ngomthelela wokushintsha kokushisa, imodi yokufaka, ukudlidliza kanye nokushintsha kwamandla amandla okuphakela amandla ku-zero ukuhamba kwe-micro pressure transmitter, ukuze kutholakale izixazululo zezinkinga ezikhona, kuhlolwa izidlulisi ezintsha zokucindezela ezincane zokuhlukanisa futhi kutholakala idatha yokuhlola.

Izihamba ezine zokucindezela ezincane zokuhlukanisa ezisetshenziswe njengamasampula okuhlola zonke zazinikwe amandla emazingeni okushisa egumbini elingaguquguquki (25℃, ushintsho olungaphezu kwe-1℃ njalo nge-10 min; umswakama ohlobene: 7%) imizuzu engama-30, bese kuba iphuzu nobubanzi balungiswa ukuze bahlangabezane ngokuphelele izidingo zokunemba komkhiqizo ngaphambi kokuhlolwa.

LEFOOAbakhiqizi bokudlulisa ingcindezi, Ithuthukisa futhi ikhiqize ukulawula ukucindezela okujwayelekile okuthembekile futhi okusezingeni eliphakeme kanye nemishini yokulawula izinga lokushisa ukuhlinzeka ngezixazululo nezinto ezintsha. Onjiniyela bethu abaqinisekisiwe bangakha isixazululo esifanele sokuqeda cishe zonke izinhlelo zokuphathwa kwamanzi. Kusukela ekuhlaziyweni kombiko wokuhlinzekwa kwamanzi, imidwebo eningiliziwe kanye nezincomo zesabelomali, ama-prototypes. Uma kunesidingo, yamukela ukubonisana.
