The rugged construction and low
cost of the LV750 Series level
switch makes it a practical choice
in a wide variety of applications for
both liquids and solids, which may
be electrically conductive or non­conductive. As a radio frequency
switch, it can tolerate reasonable
amounts of sticky build-up and still
function flawlessly. For conductive
liquids and materials with a high
dielectric constant (greater than 30)
that additionally have a tendency
to “bridge” between the probe and
container wall, a PTFE coated probe
should be used. For
compatibility considerations,
