Special X-STREAM eld housing analyzer mo-

dels can be used in Ex-zones 1, 2 or Div 2:

X-STREAM XEFN/XDFN:

These analyzer variations feature a protection

concept called "non-incendive", which means

that non-sparking and non-arcing compon-

ents, installed within a protecting enclosure,

enable installation in an European Ex-zone 2

for measuring non-ammable gases. No further

measures, such as a supply of protective gas,

are necessary.

X-STREAM XEFS/XDFS:

Equipped with a simplied pressurization system,

these eld housings can be used to measure

non-ammable gases in European Ex-zone 2.

A protective gas (e.g. pressurized air) must be

supplied when operating this model.

X-STREAM XEFZ/XDFZ:

Equipped with a simplied pressurization sy-

stem, these models can be used to measure

non-ammable gases in American zone Div 2.

A protective gas (e.g. pressurized air) must be

supplied when operating this model.
