Technical Description
The following are the main features of the new
Emerson Process Management X-STREAM
gas analyzers in brief:
• compact design with easily accessible
internal components
• customizable for a wide range of appli-
cations: different housings are available
while internal construction remains largely
identical
• a highly integrated mainboard contains
all interfaces and basic functions for the
operation of the unit
• multilingual microprocessor-controlled
user interface with liquid crystal (LCD) to
indicate measurement value and status
messages
• units for outdoor use are optionally sup-
plied with an impact tested front panel
• widerange power supply unit for worldwide
use without modication (
1
⁄2 19in units with
external PSUs)
The new X-STREAM gas analyzers can
measure up to ve different gas compon-
ents using any combination of the following
analyzing techniques (restrictions apply to
1
⁄2 19in units):
IR = non-dispersive infrared analysis
UV = ultraviolet analysis
pO
2
=
paramagnetic oxygen analysis
eO
2
=
electrochemical oxygen analysis
TC = thermal conductivity analysis
Modied resistant measuring cells are avai-
lable for use with corrosive gases and/or
gases containing solvents.
Special congurations (e.g. intrinsically safe
or infallible measuring cells) for the analysis
of combustible gases are also available.
Chapter 3 gives a detailed description of
the various measuring techniques.
Standard applications
Different housings allow X-STREAM ana-
lyzers to be tailored to the many different
applications:
• Tabletop units in
1
⁄2 19in modular design,
with IP 20 protection class
• Tabletop and rack mountable units in 19in
modular design, with IP 20 protection
class
• Stainless steel wall mountable field
housing with IP 66 / NEMA 4X protection
class for outdoor use (operating tempera-
ture -20°C to +50°C).
• Cast aluminium wall mountable field
housing with IP 66 / NEMA 4X protection
class for outdoor use (operating tempera-
ture -20 °C to +50 °C).
The various analyzer types are described in
more detail beginning with 1-13.
Installation in hazardous areas
X-STREAM analyzers in eld housings, when
tted with various protective devices, can also
be installed and operated in hazardous areas.
Available options are:
• Pressurized enclosure conforming to
ATEX directive 94/9/EC, for installation
in Zone 2.
