Abadlulisi be-LEFOO Differential Pressure balinganisa umehluko phakathi kwezingcindezi ezimbili. Lokhu kuhlukaniswa kwengcindezi ephezulu kwe-transducer kufaka ubuchwepheshe be-4-20mA Hart ukuletha imiphumela enembile yedatha Amadivayisi wokuqoqa nokulawula. Nge-Proction Level IP66 efanele ukukala uketshezi, igesi, noma umusi obonakala ukwakhiwa kwezimpawu ezikude. Inhlanganisela eyingqayizivele yezinhlelo eziningana zezinzwa kudivayisi eyodwa ivumela ukulinganiswa ngasikhathi sinye kwengcindezi yokuhlukanisa nokucindezela okuphele sire ... Kusetshenziswa ngokujwayelekile ezindaweni zokusebenza izihlungi zokubonisa izihlungi nabalandeli kanye nokulinganiswa kwezinga leziqukathi ezivaliwe. Ukunemba okungu-0.05%, (ukunemba okuqinisekile okungu-0.02% ~ 0.2%)
