The LVCN4000 Series
conductive level switch
controllers offer a wide range
of customized options to meet
any application’s need. They are
designed to control the level of
all conductive media with up to
2 different points of level control.
The LVCN4100 Series has a single
rod and is able to control one point
of level. The LVCN4200 Series can
accommodate up to 2 rods and is
able to control 2 points of levels.
Both models feature a 24 Vdc power
supply and an internal relay that
substitutes for an external relay.
As with other conductive probes,
the rods for these 2 models can be
custom-cut and made with any
process connection, such as
threaded or sanitary. In addition, the
electrodes operate on alternating
current to prevent electrolyses.
