Applications
2.2
The SafEye Xenon system may be used to monitor flammable gas
concentration in various applications, such as:
Petrochemical, pharmaceutical, and other chemical storage and
production areas
Flammable and toxic chemical storage sites, and hazardous waste
disposal areas
Refineries, oil platforms, pipelines, refueling stations, and fuel storage
facilities
Hazardous loading docks, transportation depots, and shipping
warehouses
Engine rooms
Compressor and pumping stations
Test cells

Description
LEL
Lower Explosive Limit
: The minimum concentration of a
substance (gas/vapor) in air mixture that can be ignited.
This mixture is different for every gas/vapor, measured in
% of LEL.
LEL.m
Integral of Concentration in LEL units (1 LEL = 100% LEL)
and the operation distance in meters (m).
