I-LFM77 Ukuqhuma-Differential Pressure Transmitter ukunemba okuphezulu nokuzinza okwenzelwe imvelo engozini yokuqhuma .. Ifakwe amabanga amaningi wengcindezi yokuzikhethela nokulungiswa okulula esizeni ngezinkinobho. Sebenzisa izindlu ze-ip65, le LFM77 Ukuqinisekisa ukuqhumaIsidlulisi sokucindezela okuhlukileIlungele izinhlelo zokuphathwa kwamandla, i-HVAC, i-VAV nokulawulwa kwabalandeli, ukulawulwa kokungcola kwemvelo, ukulawulwa kwengcindezi kanye nentuthu yokulawulwa kwepayipi elimile negumbi elihlanzekile, ukucindezelwa kwehhavini, nokulawulwa kokungena komoya.
Izici:
*Sebenzisa umnyombo wengcindezi ye-MEMS micro, ngokunemba okuphezulu nobubanzi bezinga lokushisa elisebenzayo;
*Isibonisi sedijithali se-LCD ngokufundwa okucacile;
*Inkinobho ye-zero etholakala, ibanga lokucindezela elungiswayo;
*Ukuzinza okuqinile, impilo yenkonzo ende;
*Izindlu zokuvikela ze-lP65.
