Technical Description
The following are the main features of the new
Emerson Process Management X-STREAM
Enhanced (hereinafter also referred to as
"X-STREAM XE") 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 display
(LCD) to indicate measurement values
and status messages
•
units for outdoor use are supplied with an
impact tested front panel
•
widerange power supply unit for worldwide
use without modification (
1
⁄
2
19in units with
internal or external PSUs)
X-STREAM XE gas analyzers can measu-
re up to five different gas components
by multiple combinations of the following
analyzing techniques (restrictions apply to
1
⁄
2
19in units, and to parallel tubing):
IR = non-dispersive infrared analysis
UV = ultraviolet analysis
pO
2
= paramagnetic oxygen analysis
eO
2
= electrochemical oxygen analysis
tO
2
= electrochemical trace oxygen analysis
TC = thermal conductivity analysis
tH
2
O = trace moisture measurement
Modified resistant measuring cells are avai
-
lable for use with corrosive gases and/or
gases containing solvents.
Special configurations (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 fi eld hou- wall mountable fi eld hou- field hou
-
sing (flameproof Ex d) with IP 66 / NEMA
4X protection class for outdoor use in
hazardous areas.
The various analyzer types are described in
more detail beginning with
page 1-14.
Installation in hazardous areas
X-STREAM XEXF field housing analyzers,
when featuring various protection methods,
can also be installed and operated in hazar
-
dous areas. Available options are:
• Non-incendive assembly (Ex nA nC) for
installation in Zone 2 and Division 2 for the
measurement of non-flammable gases.
