Differential Pressure Gage
Magnehelic® Gage in Flame-Proof ATEX Enclosure
The popular Magnehelic® Differential Pressure Gage is now available in a flame-proof
ATEX enclosure with the new ATEX approved AT22000 Series. This gage can indicate
positive, negative or differential pressures and is accurate within 2%. The Magnehelic® gage
is the industry standard to measure fan and blower pressures, filter resistance, air velocity,
furnace draft, pressure drop across orifice plates, liquid levels with bubbler systems and
pressures in fluid amplifier or fluidic systems. Optional gage construction is available for use
to either 35 psig (2.42 bar) or 80 psig (5.51 bar). Flame-proof ATEX enclosures are available
in aluminum and include a glass window for viewing process pressures status on gage face.
