Uhlolojikelele
Ama-DWP-802 series pressure transmitters aklanywe ngokukhethekile futhi akhiqizwa ukuze asetshenziswe emkhakheni wokulinganisa ingcindezi yezimboni, lapho izimo zokusebenza zivamile.Lolu chungechunge lwemikhiqizo lusebenzisa ubuchwepheshe bokukhiqiza inzwa yengcindezi yaseJalimane ethuthukisiwe.Yakhiwe inzwa ye-ceramic, isekethe ye-elekthronikhi edidiyelwe kakhulu kanye negobolondo lensimbi engagqwali, inezici zosayizi omncane, ukunemba kokulinganisa okuphezulu, ikhono eliphezulu lokuphazanyiswa kwe-anti-electromagnetic, ukufakwa okulula nokulungiswa, nokuqina.
Izici zobuchwepheshe
■ Ukukhishwa kwesistimu yezintambo ezimbili 4-20mA
■ Izinga lebanga lokucindezela lihambisana ne-DNI6 128
■ Ifakwe inzwa ye-silicon pressure ehlukanisiwe:
- Asikho isakhiwo semishini esixegayo
ukuzinza kwesikhathi eside
- Ukuphindaphinda okuhle
■ Ingcindezi yokulayisha ngokweqile izikhathi ezingu-2–4 zokucindezela kwesikali esigcwele esilinganisiwe
■ Insimbi engagqwali kanye nensimbi engagqwali inqubo yokuxhumana

■ Kuphephile ngaphakathi
Isimiso sokusebenza
Inzwa yokucindezela yochungechunge lwe-DWP-802 ibhuloho elijwayelekile le-silicon cathode elenziwe ngokufaka i-vacuum-depositing indawo ye-semiconductor ku-silicon substrate.Kukhona ungqimba lweshidi likathayela lensimbi engagqwali phakathi kwalo nendawo elinganisiwe, futhi uwoyela we-liquid-silicone ophakathi ugcwaliswa phakathi kwe-strain bridge kanye neshidi likathayela lensimbi engagqwali.
Lapho ingcindezi P isebenza eshidini likathayela futhi idluliselwa ebhulohweni lobunzima ngoketshezi oluphakathi, ukuguqulwa kwe-cathode yebhuloho kwenza ukuphuma kwebhalansi yebhuloho kube uchungechunge lwamasignali kagesi ngokulingana nokucindezela P. Bese, iguqulelwa ku-4 -20mA okukhiphayo ngokuguqulwa kwesignali kanye nesekethe yokukhulisa i-amplification kanye nesinxephezelo sezinga lokushisa.
