1. Introduction
The
CS225
Temperature
String
uses
SDI-12
digital
technology
for
simple
integration
and
reliability.
The
CS225
consists
of
an
arrangement
of
temperature
sensors
mounted
in
rugged
steel
reinforced
cable.
Temperature
points
are
over
mo
u
lded
to
provide
long-term
connection
in
all
mediums.
Each
CS225
is
manufactured
to
the
client’s
specific
requirements
and
includes
the
SGB3
to
provide
electrical
surge
protection.
NOTE:
This manual provides information only for CRBasic data loggers. For retired Edlog data logger
support, see an older manual at

2. Precautions
l
READ
AND
UNDERSTAND
the
section
at
the
front
of
this
manual.
l
Although
the
CS225
is
designed
to
be
a
rugged
and
reliable
device
for
field
use,
care
should
be
taken
when
handling
or
moving
it
to
avoid
damage.
l
There
are
no
user-serviceable
parts
and
disassembling
the
device
will
void
the
warranty.
l
The
black
outer
jacket
of
the
cable
is
Santoprene®
rubber.
This
compound
was
chosen
for
its
resistance
to
temperature
extremes,
moisture,
and
UV
degradation.
However,
this
jacket
will
support
combustion
in
air.
It
is
rated
as
slow
burning
when
tested
according
to
U.L.
94
H.B.
and
will
pass
FMVSS302.
Local
fire
codes
may
preclude
its
use
inside
buildings.
l
CAUTION—Do
not
make
tight
bends
near
the
temperature
sensor(s).
Doing
so
has
the
potential
to
damage
the
sensor
assembly.
The
minimum
bend
radius
at
any
sensor
location
is
15 cm
(6 in).
