产品描述
The LV750 series has been discontinued. Please see the LVCN6000/7000 Series as a possible alternative or contact our Flow Engineering department.
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 chemical compatibility
considerations, also request the
¾" nipple.
