1.7 X-STREAM XEXF Field Housings
1.7 X-STREAM XEXF: Field Housing With (XEF ) Single or (XDF) Dual Compartment
Field housing are conceived for outdoor use
and wall-mounting. The coated stainless steel
housing has a protection class rated IP66 /
NEMA Type 4X, offering protection against
water and dust entering the device:
IPx6
: In case of occasional flooding, e.g.
heavy seas, water shall not enter in harmful
quantities
IP6x: Protection against penetration by dust.
Live or internal moving parts are completely
protected.
An X-STREAM field housing can be fitted with
up to five measurement channels in various
combinations. The physical components can
optionally be encased in a cover. This sepa
-
rate volume can be held at a specific tempe
-
rature of up to 60 °C to minimize interference
from changes in external temperature.
Front panel
The analyzer’s display is
covered by an impact
tested glass for enhanced protection against
breakage in harsh environments.
Electrical connections
Electrical connections are provided via inter-
nal tube fittings, the cables being fed through
cable glands at the right side of the unit (
Fig. 1-11). The front cover of the housing
swings open to the left once the fasteners
have been released.
Connection to power supply
Mains power is supplied via screw-type termi-
nals with integrated fuse holders at the right
side of the housing, near the front. The wide
range power supply unit mounted internally
enables the analyzers to be used worldwide.
Interface signals
Up to two digital I/O cards may be installed.
If so, on a label nearby, they are labeled
"X4.1" for the first I/O board, and "X4.2" for
the second.
Detailed technical details on the various inter-
faces can be found at
2-2. The configu
-
ration of the screw-type terminal adapters are
described in
the software settings in
interface and software menus'.
Gas connections
Depending on the configuration of the unit
(number of channels, series or parallel pi
-
ping), up to eight tube fittings are provided for
the supply of sample and calibration gases.
The assignments of the fittings is given on an
adhesive label situated near the fittings.
A further optional tube fitting enables the
housing to be purged
to minimize interference
from the ambient atmosphere,
or when measu-
ring corrosive and/or flammable gases.

Dual compartment variation XDF
The dual compartment variation XDF sup-
ports separating electronics and physics,
e.g. for measurement of corrosive or solvent
gases. For such applications the electronics
are installed in the upper compartment, while
measurement physics are in the lower com-
partment. This separation is also available as
gastight version.
XDF also provides more space e.g. for instal-
lation of optional signal converter elements for
system integrators.
