Offering high reliability at low cost,
the LVK-130 and LVK-140 Series
level switch is recommended for
many OEM applications. Extremely
compact, the switch is ideal for
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
LVK-150 Series level switch will
provide highly stable and accurate
level detection. A protective slosh
shield dampens turbulent liquids.
The all polypropylene construction
is ideal for beverage dispensing
and ice machines. The PFA
LVK-190 Series switches are
resistant to many corrosive
materials. The sensor mounts
vertically at either the top or bottom
of the tank and is easy to install.
