Differential Pressure Gages
The popular Magnehelic®Differential Pressure Gage is now available in a flameproof ATEX enclosure with the new ATEX approved AT22000 Series. This gage can
indicate positive, neg ative or dif ferential pressures and is accurate wit hin 2%. The
M
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). Flameproof ATEX enclosures are available in aluminum and include a glass window for viewing
process pressures status on gage face.
Important notes for installation:
• Cables must be fitted through 1/2˝ NPT cable gland or ATEX conduit (not supplied
• Make sure after cabling to close tight cover and cable gland, in order to keep IP66
• Open cover only after de-energizing instrument.
• Attention: Check local safety rules and warnings on unit and manual for a correct
