I-Explosion-proof Differential Pressure Transmitter LFM77

Lefoo I-Explosion-proof Differential Pressure Transmitter LFM77

I-LFM77 i-Explosion-proof Differential Pressure Transmitter iwumshini onembile futhi ozinzile oklanyelwe indawo enengozi yokudubula. Ihlonyiswe ngezilinganiso zokucindezela eziningi ezikhethwayo nokulungiswa kalula endaweni ngezinkinobho. Isebenzisa i-ip65 housing, le LFM77 Explosion-proof differential pressure transmitter ifanele amasistimu okuphatha amandla, i-HVAC, i-VAV nokulawula ama-fan, ukulawula ukungcoliswa kwemvelo, ukulawula ukucindezela nesmoke hood yamapayipi angashintshi kanye negumbi elihlanzekile, ukufaka umfutho we-oven, nokulawula ukuvuleka kwe-boiler.


Izici

* Sebenzisa i-MEMS micro pressure core, ngokunemba okuphezulu nobubanzi bokushisa obubanzi;

* I-LCD digital display enokufunda okucacile;

* Inkinobho ye-Zero iyatholakala, ububanzi bokucindezela buyalungiseka;

* Ukuzinza okuqinile, impilo ende yesevisi;

* Indawo yokuvikela ye-lP65 housing.
