Offering high reliability at a low cost,
the LV-60 Series level switch is
recommended for many OEM
applications. The all-polysulfone
construction provides excellent
chemical resistance and is rated to a
maximum temperature of 107°C
(225°F). Extremely compact, the
switch is ideal for applications
involving restricted or limited space.
The reed switch design allows the
user to select either normally open or
normally closed by simply removing
the retaining clip and inverting the
position of the float.
When turbulent tank conditions
prevail, the LV-70 Series level switch
will provide highly stable and accurate
level detection. A protective slosh
shield allows contact with non-static,
highly contaminated liquids and
minimizes the effects of turbulence and
motion. Mounting brackets attach to a
wall, bracing, sounding tube, or any
similar surface.
The LV80’s all-CPVC construction is
resistant to many acids, bases, and
aqueous solutions, making these
switches well suited for chemical
and plating applications. The sensor
mounts vertically at either the top
or bottom of the tank and is easy
to install. Visit omega.com/level_ref
