LFT720A Flange-mountedDifferential PressureI-Transmitter yakhiwe i-LFT710 Differential Pressure Transmitter kanye neflange enshelelekile yezinga loketshezi. Phakathi kweflange nenzwa, kusetshenziswa uwoyela we-silicon nezinye izinto zokugcwalisa ukudlulisa ingcindezi, ukuvimbela umediya olinganiswayo ukuba awudlule emhubheni wethonya bese ethinta isilinganiso. Umthelela womediya olinganiswayo odlula emhubheni wethonya uhlanganisa: ukwakheka kwamakristalu, ukuqina, ukuhwamuka (ukubila), ukujiya (ukuhlangana), ukuhlukaniswa (ukuguqulwa okukhulu), njll. I-transmitter isetshenziselwa ukulinganisa izinga loketshezi, ukugeleza, kanye nomfutho woketshezi, igesi noma umusi, bese iguqula lokhu kube isignali ephumayo engu-4~20mA. Isimiso sokusebenza se-LFT720A Flange-mountedDifferential PressureI-Transducer ifana ne-LFT710 Differential Pressure Transmitter ngaphandle kokuthi indlela yokudlulisa ingcindezi ohlangothini lwengcindezi enhle yehluke kancane, okungukuthi ingcindezi esebenza ohlangothini lwengcindezi ephezulu iqala ukudlula ngedayaframu yeflange yezinga loketshezi kanye noketshezi olugcwalisiwe, bese idlula emzimbeni we-transmitter, ekugcineni ifinyelele ohlangothini lwengcindezi ephezulu lwenzwa yokulinganisa.
Isici
