I-LFT720B Double Flange-mounted Differential Pressure Transmitter yakhiwe nge-LFT710 Differential Pressure Transmitter kanye ne-flange encane eshiselwe ekude enetyhubhu ye-capillary. Phakathi kwe-flange nenzwa, kusetshenziswa amafutha e-silicon nezinye izinhlobo zoketshezi lokugcwalisa ukuze kudluliselwe ingcindezi, ukuvimbela ukuthi into elinganiselwayo idlule epayipini le-impulse, okuyinto engathikameza ukulinganisa. Umthelela wokudlula kwento elinganiselwayo epayipini le-impulse uhlanganisa ukwenza amakristali, ukuqina ukuhwamuka (ukubilisa), ukuhlanjululwa kwe-condensation (ushintsho olukhulu) nokunye. I-Transmitter isetshenziselwa ukukala izinga loketshezi, ukugeleza kanye nengcindezi yoketshezi, igesi noma isitimu, bese ikuguqula kube okokukhipha isiginali ye-4~20 mA. Isimiso sokusebenza se-LFT720B Double Flange-mounted Differential Pressure Transducer siyefana ne-LFT710 Differential Pressure Transmitter ngaphandle kokuthi indlela yokudlulisa ingcindezi ohlangothini lwengcindezi enhle ihluke kancane, okusho ukuthi ingcindezi esebenza ohlangothini lwengcindezi ephakeme iqale idlule ku-diaphragm noketshezi lokugcwalisa lwe-flange ekude, bese idlulela emzimbeni we-transmitter ngetyhubhu ye-capillary, bese ekugcineni ifika ohlangothini lwengcindezi ephakeme lwenzwa yokulinganisa.
