PLEASE
READ
THE
ENTIRE
MANUAL
PRIOR
TO
INSTALLING
OR
USING
THIS
PRODUCT.
This
manual
includes
information
on
all
models
of
OMEGA
ENGINEERING
Non
‐
Intrusive
RF
Capacitance
Level
Switch:
LVP
‐
51
‐
R.
Please
refer
to
the
part

located
on
the
sensor
label
to
verify
the
exact
model
which
you
have
purchased.
User’s
Responsibility
for
Safety:
OMEGA
ENGINEERING
manufactures
a
wide
range
of
liquid
level
switches
and
technologies.
While
each
of
the
these
switches
are
designed
to
operate
in
a
wide
variety
of
applications,
it
is
the
user’s
responsibility
to
select
a
switch
model
that
is
appropriate
for
the
application,
install
it
properly,
perform
tests
of
the
installed
system,
and
maintain
all
components.
The
failure
to
do
so
could
result
in
property
damage
or
serious
injury.
Proper
Installation
and
Handling:
Because
this
is
an
electrically
operated
device,
only
properly
trained
staff
should
install
and/or
repair
this
product.
The
adhesive
on
the
fitting
is
for
temporary
installation
only.
For
permanent
installation,
the
fitting
for
the
sensor
should
be
welded,
glassed
or
strapped
to
the
tank
itself
using
approved
plastic
welding
techniques.
Do
not
install
the
LVP
‐
51
‐
R
sensor
on
a
metal
tank,
or
within
6"
of
any
metal
pipe
or
fitting.
Mounting
Bracket:
The
LVP
‐
51
‐
R
sensor
may
be
mounted
in
the
PE
(LVP
‐
91)
or
PP
(LVP
‐
92)
bracket.
Make
sure
that
the
fitting
is
compatible
with
the
tank
it
will
be
applied
to.
Material
Compatibility:
The
sensor
itself
is
not
designed
to
be
immersed.
It
should
be
mounted
in
such
a
way
that
it
does
not
normally
come
into
contact
with
fluid.
Its
case
is
made
out
of
Polysulfone
(PSO).
Refer
to
an
industry
reference
such
as
the
Compass
Corrosion
Guide
to
ensure
that
compounds
that
may
splash
onto
the
controller
housing
will
not
damage
it.
Such
damage
is
not
covered
by
the
warranty.
Wiring
and
Electrical:
The
supply
voltage
used
to
power
the
LVP
‐
51
‐
R
sensor
should
never
exceed
a
maximum
of
36
volts
DC.
Electrical
wiring
of
the
sensor
should
be
performed
in
accordance
with
all
applicable
national,
state,
and
local
codes.
Flammable,
Explosive
and
Hazardous
Applications:
The
LVP
‐
51
‐
R
switch
is
not
rated
for
use
in
hazardous
locations.
Refer
to
the
National
Electric
Code
(NEC)
for
all
applicable
installation
requirements
in
hazardous
locations.
DO
NOT
USE
THE
LVP
‐
51
‐
R
GENERAL
PURPOSE
SWITCH
IN
HAZARDOUS
LOCATIONS.
Warning
The
rating
for
the
relay
is
60
VA.
Do
not
install
the
LVP
‐
51
‐
R
level
switch
on
a
metallic
tank,
or
within
6"
of
any
metallic
object.
Metal
will
adversely
affect
the
dielectric
sensitivity
of
the
sensor.
OMEGA
ENGINEERING's
LVP
‐
51
‐
R
sensors
are
not
recommended
for
use
with
electrically
charged
application
liquids.
For
most
reliable
operation,
the
liquid
being
measured
may
need
to
be
electrically
grounded.
