AT11910系列 防爆型差壓開關(guān)-德威爾Dwyer

Our most popular Differential Pressure Switch is now available in a flame-proof ATEX approved package in the SERIES AT11910. This pressure switch combines advanced design and precision construction to make these switches able to perform many of the tasks of larger, costlier units. For air and non-combustible compatible gases, the AT11910 Series switches have set points from 0.07 to 20 in w.c. (1.8 to 508 mm). Set point adjustment is easy with range screw located inside the switch enclosure. Series AT11910 ATEX enclosures are available in aluminum enclosures and ideal for low pressure, hazardous area applications.
