Terms used in this manual
Dilution
The continuous supply of a protective gas,
after purging, at such a rate that the
concentration of a flammable mixture inside
the pressurized enclosure is maintained at
a value outside the explosive limits except
in a dilution area.
Pre-Purging
The pre-purging phase serves to remove any
combustible gas out of the analyzer’s
enclosure prior to switching on the analyzer.
Flammable Gas(es)
Gases and gas mixtures are assigned to be
flammable if they might become ignitable
when in a mixture with air.
„Leakage Compensation“
In EEx p „leakage compensation mode“ just
as much protective gas is used to hold the
required overpressure compared to
atmospheric.
„Continuous Flow“
In EEx p „continuous flow mode“ the
protective gas flows with higher rates
through the enclosure. Flow rates are
calculated to hold an overpressure of > 1
mbar compared to atmospheric.
Protective Gas
Air or inert gas used for purging and
maintaining an overpressure and, if
required, dilution.
