concept called "non-incendive" (Ex n), which
means that non-sparking and non-arcing com-
ponents, 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 XLFS/XXFS:
Equipped with a simplified 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 XLFZ/XXFZ:
Equipped with a simplied pressurization system
(z-purge), 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.
