INSTALLATION ELECTRICAL
Through Wall Installation:
Omega’s powered level switches may be installed through the top,
side or bottom of a tank wall. The sensor has male 3/4" NPT threads
on either side of a 15/16" wrench flat. This enables the user to select
the sensor’s mounting orientation, installed outside of the tank in, or
inside of the tank out.
Supply Voltage:
The supply voltage to the powered level switch should never exceed
a maximum of 36 VDC. Omega controllers have a built-in 13.5 VDC
power supply which provides power to all of Omega’s electrically
powered sensors. Alternative controllers and power supplies, with a
minimum output of 12 VDC up to a maximum output of 36 VDC,
may also be used with the powered level switch.
Required Cable Length:
Determine the length of cable required between the powered level
switch and its point of termination. Allow enough slack to ensure the
easy installation, removal and/or maintenance of the sensor. The
cable length may be extended up to a maximum of 1000 feet, using a
well-insulated, 14 to 20 gauge shielded four conductor cable.
Wire Stripping:
Using a 10 gauge wire stripper, carefully remove the outer layer of
insulation from the last 1-1/4" of the sensor's cable. Unwrap and dis-
card the exposed foil shield from around the signal wires, leaving the
drain wire attached if desired. With a 20 gauge wire stripper, remove
the last 1/4" of the colored insulation from the signal wires.
Signal Outputs (Current sensing):
The standard method used by Omega controllers; this technology uses
only two wires (Red and Black). The sensor draws 5 mAwhen it is dry,
and 19 mA when wet. NC/NO status must be set by the controller. The
White and Green wires are not used.
Multi-Point Installation:
Omega’s LVM-10 series mounting system is an in-tank fitting which
enables users to install up to four OMEGA sensors of any technology,
to any depth, along the entire length of track. LVM-10 series may be
installed through the top wall of any tank using a standard 2" NPT
tank adapter. If no tank top installation is available, Omega's side
mount bracket, LVM-30, enables LVM-10 series to be installed
directly to the side wall of a tank.
Single-Point Installation:
Omega’s LVM-50 series mounting system is an in-tank fitting which
enables users to install one OMEGA sensor, of any technology, to a
specific depth. The Omega sensor may be installed onto the 3/4" NPT
adapter at the end of the LVM-50 series. LVM-50 series may be
installed through the top wall of any tank using a standard 2" NPT
tank adapter. Omega's side mount bracket, model LVM-30, may also
be used if top wall installation is not available.
Signal Output (Relay switching):
Allows the sensor to switch a small load on or off directly, using an
internal 1A relay (60 VAC/60 VDC). Omega’s powered level switch-
es features 4 wires (red, black, white and green) and a shield wire. The
NO/NC status is set by the polarity of the voltage feeding the red and
black wires. The green wire is the common for the relay and the white
wire is the NO or NC, depending on the polarity of red and black.
