Dimensions: mm (in)
Compact, rugged, and virtually
maintenance-free, the LV-90 Series
level switch can meet the needs of
large-volume OEMs. The sensor is
designed for side mounting into tanks
that have restricted space or
inaccessible tops or bottoms. The
all-polysulfone construction makes
these switches compatible with a wide
range of chemicals and is suitable for
food processing applications.
Magnetic SPST switch operation is
normally open (dry) when units are
installed with float downward, or
normally closed (dry) when installed
with float upward.
The LV-100 Series liquid-level switch
requires side mounting into vessels,
and is highly reliable. The unit should
be installed in environments that are
free from excessive contamination
and high shock. LV-100 models are
available with either Buna or 316 SS
float material, both of which have
positive float and cam action. These
versatile level sensors feature SPDT
switches that can be wired as either
normally open or normally closed;
other models feature SPST switches
that are dedicated as either normally
open or normally closed. For highpressure applications, the switches
constructed of 316 SS will withstand
up to 900 psi. Visit omega.com/
level_ref for maximum
voltage/current ratings.
