X-STREAM F (Field Housing)

This IP66 / NEMA 4X protected housing is
intended for outside wall mounting: The housing
(fig. 1-4) is made of painted stainless steel.
Gaskets protect against water and dust.
The front panel is located behind a safety glass
providing protection against mechanical impact
and shows a 4x20 characters alphanumeric
display and 3 status LEDs. The keypad as it is
used to operate the tabletop analyzer is re-
placed by sensor fields, operated with a mag-
netic tool (fig. 1-5).
Electrical connections are provided by internal
screw terminals, the cables enter the housing
via cable glands located at the instruments
bottom side (fig. 1-6).
Gas fittings are located at the instrument's
bottom side, too.
The front door opens vertically by 180° provi-
ding easy access to internal components.
Removing the hinge bolts even allows to
completely remove the front door.
An optional fitting facilitates purging the
instrument with inert gas to minimize influences
caused by ambient air when measuring low
ranges of select gases (e.g. CO, CO2). The
This instruction manual at hand does not deal with X-STREAM analyzers
intended to be used in hazardous areas!
Installation, startup and maintenance are described in detail in a separate
instruction manual, shipped together with each such analyzer, and are not
subject of this current instruction manual!

inert gas may exhaust the analyzer through a
separate fitting (into an exhaust system) or by
leakages in the housing (into ambient).
Purging the physical components with air or
inert gas may also be needed when measu-
ring aggressive and/or flammable gases: In
addition to the purge fitting an internal box is
installed, covering the physical components.
This forces the purge medium to flow around
all other (electronic) components before is
circulates around the physics and exhausts the
analyzer through a separate outlet fitting into
an exhaust system. In case of internal leakage
this ensures that the aggressive/flammable
gas is not flushed towards the electronics
causing hazards of corrosion and/or explosion
and provides operator safety.
Provided with an appropriate pressurization
system the X-STREAM F is suitable for installa-
tion in hazardous areas.
