OMEGA’s conductivity level
switches offer a wide range of options to meet any
application’s needs. They are
designed to control the level of all
conductive mediums, offering up to
5 different points of level control.
Models are available with fixed rigid
rods, with removable rigid rods, or
with pendular electrodes attached
to the housing with cables. These switches suit applications involving
both alarm point detection and on/off
pump valve control. Installation is
easy and operation is
The probes work through the
variation of the electrical resistance
between the reference electrode and
the level-control electrode.
Conductivity level switches detect
the level resistance when their
electrodes are covered by the
An electrically conductive tank wall
can be used as the reference
electrode. If the tank is made of
plastic, concrete, or any other nonconductive
material, an additional
electrode is required as a reference.
The LVCF switches can
accommodate up to five 316 SS
fixed rods for 5 different levels of
control. The rods are isolated with a
PTFE joggle and can be coated with
PTFE when the probe is used with
aggressive or sticky media that cause
buildup. The user can easily modify
operating levels in the tank by
cutting the length of the electrodes.
The LVCF switches are rugged and
compact and have no moving parts.
This makes them reliable for
controlling conductive media as well
as for high-pressure applications.
LVCF models are compatible with
LVCN-200 Series controllers only.
The LVCR models offer the same
features as the LVCF, plus
removable 316 SS threaded rods
that make it possible to switch the
rods. Rods can be ordered
separately in longer length and can
then be custom cut. Removable
rods make the system more
versatile, easier to handle, and
more forgiving if the rod’s length is
LVCR models are compatible with
LVCN-200 Series controllers only.
Along with the same features as the
rigid rod probes, LVCP pendular
probes can accommodate up to
5 model CLE-P electrodes. The
LVCP probes are ideal for deep
measurements in wells or large
tanks where long rods would be
impractical, but they work equally
well for shorter-length applications.
The electrodes are suspended from
PVC cables that allow for longer
lengths, as well as for different
applications and installations. LVCP
models are compatible with
The electrode model CLE-P is the
simplest version of all conductivity
probes. A small polypropylene
enclosure houses a 316 SS rod that
is attached to a PVC cable. This
option eliminates the need for a
LVCN-200 Series conductive liquid
on/off level controllers are used to
power all level probes. The LVCN-
200 models are electronically
controlled devices that open and
close an electrical contact to effect
the operation of other devices in the
same, or another, electrical circuit.
The LVCN-201/202 models can
control the differential of minimum
and maximum level, with an
adjustment for sensitivity. The relay
has 1 reverse SPDT contact.
The LVCN-203/204 models control
2 independent levels and 2 reverse
SPDT contacts. They also include a
The LVCN-200 Series is designed
so that multiple units can be used in
combination to provide a variety of
control functions, including multiple
alarms and on/off control for
Both models are available with
DIN rail sockets or with screws.
