Introduction
Technology
to
redefine
reliability
The
Rosemount
5408
and
5408:SIS
are
optimized
for
reliable
and
accurate
performance
even
in
challenging
process
conditions.
FMCW
technology
maximizes
radar
signal
strength
and
produces
a
robust
and
reliable
measurement.
The
transmitters
are
self-powered
for
up
to
two
seconds
to
maintain
operation
despite
cable
glitches
or
lightning.
The
minimum
lift-off
voltage
is
9
Vdc
for
FOUNDATION™
Fieldbus
and
12
Vdc
for
HART®
.
Ease-of-use
at
every
touch
point
The
Rosemount
5408
and
5408:SIS
are
designed
to
simplify
operator
tasks.
They
deliver
ease-of-use
at
every
touch
point,
from
the
pictorial
user
instructions
and
graphical
intuitive
wizards
to
the
PTFE
seal
that
requires
no
O-ring
material
for
simplifying
model
selection.
Dedicated
to
safety
The
Smart
Diagnostics
Suite
provides
operators
with
early
alerts
in
case
of
antenna
build-up,
weak
power
supply,
or
abnormal
surface
conditions.
Also,
a
local

The
Rosemount
5408:SIS
is
the
ideal
choice
for
functional
safety
such
as
overfill
prevention.
It
is
safety
certified
(SIL
2/SIL
3),
supports
long
proof-test
intervals
guaranteed
to
suit
your
schedule,
and
can
be
tested
remotely
without
any
process
interruption.
Application
examples
The
Rosemount
5408
and
5408:SIS
are
ideal
for
level
measurements
over
a
broad
range
of
liquid
and
solids
applications.
The
transmitters
are
virtually
unaffected
by
changing
density,
temperature,
pressure,
media
dielectric,
pH,
and
viscosity.
Non-contacting
radar
level
is
ideal
for
harsh
conditions
such
as
corrosive
and
sticky
media,
or
when
internal
tank
obstructions
are
a
limiting
factor.
Storage
and
buffer
tanks
The
Rosemount
5408
provides
accurate
and
reliable
level
measurement
for
both
metallic
or
non-metallic
vessels
containing
almost
any
liquid
(e.g.
oil,
gas
condensate,
water,
chemicals).
Reactors
The
Rosemount
5408
is
ideal
for
the
most
challenging
applications,
including
reactors
where
there
can
be
agitation,
foaming,
and
condensation,
as
well
as
high
temperatures
and
pressures.

Blenders
and
mixers
The
Rosemount
5408
can
help
you
withstand
the
rigors
of
blenders
and
mixing
tanks.
Easy
to
install
and
commission,
it
is
also
unaffected
by
virtually
any
fluid
property
change.
Open
atmospheric
applications
The
Rosemount
5408
measures
reliably
in
open
applications,
from
short
range
sumps
or
ponds
to
long
range
dams.
Still
pipe
and
chamber
installations
The
Rosemount
5408
is
a
great
choice
for
level
measurement
in
tanks
with
small
diameter
still
pipes.
It
may
also
be
used
in
chambers,
but
guided
wave
radar
is
generally
the
best
fit
for
these
applications.
Bulk
solids
The
Rosemount
5408
is
the
ideal
solution
for
small-
to
medium-sized
silos
with
rapid
level
changes.
The
narrow
beam
avoids
internal
obstructions
while
still
keeping
good
level
measurement.![]()
