Technical Description
1.1 Analyzer Variations Covered by This Manual
1.2 Application and Principle of Operation
X-STREAM non-incendive gas analyzers
enable the measurement of gas components
in hazardous areas (Ex zones) without the
need of additional external protective equip-
ment:
They have been designed in a way to be built
of selected components, which do not create
arcs, sparks nor hot spots under normal ope-
rating conditions. Thus they cannot ignite a
surrounding explosive atmoshere, even if it
penetrates the analyzer enclosure.
TThese protection methods (summarized un-
der the topic „non-incendive“) are specifi ed by
standard CAN/CSA 60079-15. Thus the ana-
lyzers can be operated in hazardous areas
classifi ed Divison 2 (Div. 2) North-American
standards (CSA-C/US approval).
In these areas explosive atmosphere is not
likely to exist under normal operating condi-
tions, and if so, for short time periods only.
