Sihumusha umehluko phakathi kwe-monocrystalline silicon pressure transmitter ne-monocrystalline silicon , omunye umgomo wokusebenza, kanti omunye ukubukeka.
1. Umgomo osebenzayo wokudlulisa ingcindezi
Isidlulisi sokucindezela kwe-monocrystalline silicon sifaka amayunithi amabili asebenzayo, iyunithi enkulu kanye neyunithi elisizayo.
Iyunithi eyinhloko ifaka inzwa nokuxhuma kwenqubo. Umgomo wokusebenza unjengokulandelayo: inqubo yenqubo ifaka ingcindezi ku-diaphragm yokulinganisa ngokusebenzisa okuguquguqukayo, Ukuhlukanisa i-diaphragm nokugcwalisa uketshezi, futhi eyodwa ekugcineni kwe-diaphragm yokulinganisa ixhunywe emkhathini (ukulinganisa kwengcindezi ye-gauge) noma i-vacuum (izilinganiso zengcindezi ngokuphelele).
Ku-Umkhiqizi wokudlulisa ingcindezi, Lapho ingcindezi elilinganisiwe idluliselwa ku-chip ye-sensor silicon ngokusebenzisa i-diaphragm yokulinganisa nokugcwalisa uketshezi, inani lokumelana kwe-sensor silicon chip kuyashintsha, okuholele ekushintsheni kwamandla okukhipha ohlelweni lokutholwa. Amandla okukhipha alingana nokushintshwa kwengcindezi, bese aguqulwa abe ngumkhiqizo wesiginali ojwayelekile yiyunithi yokuzivumelanisa kanye ne-amplifier.
2. Umgomo wokusebenza wokudlulisa ingcindezi yokuhluka
I-monocrystalline silicon ehlukanisa ingcindezi ifaka phakathi amayunithi amabili asebenzayo, iyunithi enkulu kanye neyunithi elisizayo.
Iyunithi eyinhloko ifaka inzwa nokuxhuma kwenqubo. Umgomo wokusebenza unjengokulandelayo: Imodyuli yenzwa yamukela ubuchwepheshe obunezinhlangano zonke futhi ine-diaphragm yokulayishwa ngokweqile ngaphakathi, inzwa yengcindezi ephelele kanye no-Inzwa yengcindezi ye- hvac. Inzwa yengcindezi ephelele ifakwe kuphela ohlangothini lwengcindezi ephezulu yenzwa ivumela njengenani lenkomba lokucindezela okumile isinxephezelo.
Uhlangothi lwengcindezi olubi lwenzwa yokucindezela ehlukile luxhunywe kwigumbi lokucindezela eliphansi lenzwa. Lapho ingcindezi yokuhlukanisa elilinganisiwe idluliselwa ku-chip ye-sensor silicon nge-diaphragm yokuhlukanisa kanye noketshezi olugcwalisayo, inani lokumelana kwe-chip yenzwa kuyashintsha, okuholele ekushintsheni kwamandla okukhipha ohlelweni lokutholwa. Amandla okukhipha alingana nokushintshwa kwengcindezi, bese aguqulwa abe ngumkhiqizo wesiginali ojwayelekile yiyunithi yokuzivumelanisa kanye ne-amplifier.
Isidlulisi sokucindezela kwe-monocrystalline silicon samukela ubuchwepheshe be-silicon sensor ephezulu, uhlobo olusha lokudlulisa ngokuqinile okuphezulu, ngokususelwa ezingxenyeni ze-elekthronikhi nge-microprocessor, ukufeza ukuxhumana namadivayisi ensimini. Abadlulisi be-crystal silicon bafaka ingcindezi ye-gauge, ingcindezi yokuhlukanisa, ingcindezi ephelele, Ingcindezi ephezulu yokuhlukanisa kwengcindezi kanye nezinye izinhlobo eziningi. Kusetshenziswa ku-petroleum, imboni yamakhemikhali, amandla kagesi, insimbi, izindaba zamanzi, ukuphuza kanye neminye imikhakha yezimboni.
1. Ukuxhumana ngqo
Uhlobo lokuxhuma okuqondile ngokuvamile lukalala ingcindezi ye-mediam. Indlela yokuxhuma yi-M20 * 1.5 noma i-1/4 NNT intambo yangaphandle noma ukuxhuma kwentambo yangaphakathi.
2. Ukuxhumana okungaqondile
Uhlobo lokuxhuma okungaqondile lufana nohlobo lukaRosemount. Ngezansi ixhunywe kwipayipi ngeqembu le-valve noma i-flange, futhi ingcindezi noma ingcindezi yokwehluka kwendlela ingalinganiswa. Ngokuvamile, ingcindezi yokuhlukanisa iningi.
Ukuqapha:
(1) Ngemuva kokulinganiswa, insimbi igcwele ibhokisi (GB / T 13384-2008) ukuyivikela ekulimaleni.
(2) Ukugcinwa kwensimbi akudingi ukuphathwa okukhethekile. Awukho umkhawulo wesikhathi sokugcina, kepha impilo yeshalufu isahambisana nesikhathi esichazwe yinkampani.
(3) I-magama yomkhiqizo ifaka imininingwane efanele njengenombolo ye-serial, ibanga lokulinganisa, izinga lokunemba, amandla okufaka, okukhipha, nosuku lokukhiqiza. Qiniseka ukuthi unikeza inombolo yensimbi yensimbi yemibuzo ebalulekile.
