The
GSE
Models
3501s
and
3551s
instruments
are
approved
by
FM
Approvals
as
intrinsically
safe
for
use
in
hazardous
areas.
An intrinsically
safe
device
has
been
proven
through
calculation
and
testing that
it
cannot
produce
enough electric
or
thermal
energy
under
normal
or
fault
conditions
to
cause ignition
of
flammable
material
present
in
the
atmosphere.
The
hazardous
area
is
defined
in
terms
of
how
long
the
hazard
is
present,
how
easily
it
is
ignited,
and
what
maximum temperature
can
be
present.

locations
are
those
in
which
hazardous
concentrations
of
flammable
gases
or
vapors
exist
continuously, intermittently
or
periodically
under
normal
operating
conditions.
Electrical equipment
for
use
in
such
locations
may
be
“explosion
proof,”
“intrinsically
safe,”
“purged”
or
otherwise
protected
to
meet
the intent
of
Articles
500
of
the
National
Electrical
Code@.
Explosion
proof
protection consists
of
equipment
designed
to
be
capable
of
containing
an
internal
explosion
of
a
specified
flammable
vapor-air
mixture.
In
addition,
the
equipment must operate at
a
safe
temperature
with
respect
to
the
surrounding
atmosphere.
Intrinsically
safe
electrical
equipment
and
associated
wiring
are
incapable
of
releasing sufficient
electrical
or
thermal
energy
to
cause
ignition
of
a
specific
hazardous
material
under
“normal”
or
“fault”
operating
conditions.
Normal
operation
assumes
maximum
supply
voftage
and
rated
environmental
extremes;
fault
conditions
assume
any
single
or
dud
independent
electrical
faults
plus
field
wiring
open,
shorts
or
connections
to
ground. Equipment
rated
as
intrinsically
safe
is
recognized
by
Article
500
as
safe
for
use
in
hazardous
locations
without
special
enclosures
or
physical
protection that
would
otherwise
be
required.
Purged
systems
have
fresh
air
or
an
inert
gas
under positive
pressure
to
exclude
ignitable
quantities
of
flammables
from
the
electrical
equipment
enclosure.
Equipment

locations
are
those in which hazardous concentrations
of

of operation.
As
such,
equipment
and

wiring
which
are
incapable
of
reIeasing
sufficient electrical
and
thermal
energy
to
ignite
flammable
gases
or

VALUATION
C
ONCEPT
The
Model
35015
and
3551s
indicators
have
been
approved
under
the
entity
evaluation
concept,
which
allows
the
interconnection
of
intrinsically
safe
devices
in
hazardous
areas
even though these devices
were
not specifically
approved
in
this combination. This
means
that not only
can
the instrument
be
used with
GSE
FM
Approved Ioadcells
and
peripherals, but
they
can
also
be used with
any
manufacturer’s
FM
Approved
loadcells and
peripherals
provided
that they
have
matching
entity ratings
and
are
approved
for
the
appropriate
hazardous
area.
The
criteria
for
interconnection
is
that
the maximum input
voltage
and
current, which intrinsically
safe
apparatus
can
receive
and
remain intrinsically
safe,
considering faults, must
be
equal
to
or
greater than the
maximum
output
voltage
and
current
levels
which
can
be
delivered by the associated
apparatus,
considering
faults
and
applicable factors.
In
addition,
the
maximum
internal
capacitance
and
inductance
of
the
intrinsically
safe
apparatus, including ihterconnecting wiring,
must
be
less
than
or
equal
to
the
maximum
allowed capacitance
and
inductance which
can
be
safely
connected
to
the
associated
apparatus.
If
these
4
criteria
are
met,
then
the
combination
may
be
connected
and
remain intrinsically
safe.
If
the
specific
capacitance
and
inductance
ratings
of
the
wiring
are
unknown,
use
a
capacitance
of
6OpF/ft
and
an
inductance
of
0.2uWft.
When
connecting
a
Model
350IS
or
3551s
to
another
intrinsically
safe
device,
the
entity
ratings
must
be
compared
and satisfy
the
