The LVCN6000/7000 Series is a
capacitance switch ideal for low and
high level detection for both liquid
and solids. The LVCN6000/7000
Series can also detect level without
being in contact with the product
through a sight glass. Unlike other
capacitance probes, the
LVCN6000/7000 series can detect
LVCN6000/7000
any type of conductive, nonconductive
or low dielectric
materials with extremely accurate
performance, almost complete
immunity from build up, temperature
changes or condensation. In
applications with plastic or concrete
tanks this series does not require an
external reference.
The sensor operates in a manner
that is similar to a simple capacitor.
A high frequency oscillator is located
within the tip of the probe. When the
tip of the probe comes in contact
with the medium, the frequency of
the oscillation reaches a preset point
and the detection circuit signals the
switch to change state.
The LVCN6000/7000 series is a
compact switch that can be made
with many types of process
connections, such as threaded
flange or sanitary. The LVCN6000/
7000 series is made with rigid rod
or cable and both can be supplied
in extended versions. The rigid rod is
made with a strong and durable
polyacethal plastic for standard units
and is also available in PVC or
PTFE. Probes are available in
24 Vdc (LVCN7000) or 85 to 240 Vac
(LVCN6000) powered versions.
Note: These switches are not designed for
use with mediums with high dielectrics
such as mayonnaise or shampoo with high
salt content.
