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.
