Technical Data - Emerson 2120 Quick Start Manual

December 2016
Aggressive substances – e.g. acidic liquids or gases that may attack metals or
solvents that may affect polymeric materials.
Suitable precautions – e.g. regular checks as part of routine inspections or
establishing from the material's data sheet that it is resistant to specific
chemicals.
7. The Rosemount 2120 meets the requirements of clause 6.3.12 (Isolation of
circuits from earth or frame) in EN 60079-11 (IEC 60079-11).
