APPLICATION EXAMPLES
Capacitive sensors detect all kind
of materials, liquids, bulk materi-
al, or objects.For level control non-flushmountable Sensors are recom-
mended.For
detection at a distance theflush mountable sensors are the
right choice. Filling
level detection withcapacitive sensors (KAS)
flushmountable KAS
non-flush mountableKAS Detection of the content of a
cardboard package e.g. tins withcapacitive sensors (KAS) Content control of tablets in blister
packages with capacitive sensors
(KAS) Counting of objects with capacitivesensors (KAS) e.g. jars of mustard Analogue measurements in the
automobile industry with
capacitive sensors (KAS)
e.g. position of the
indicator
Inductive sensors (IAS) and magneto
resistive Sensors (MRS) detect
metal objects in machines, plants
and vehicles.They serve as pulse generator forspeed controls, position controls,
distance and counting measure-
ments. Detection of a
gear wheel or cam
wheel with inductive sensors
(IAS) or magneto resistive
sensors (MRS) Capacitive sensors of the KXS-Extreme-series operate on the basis of the three-
industrial electrode principle. With this measuringprinciple, one electrode is removed to the
outside. The protective conductor-poten-
tial PE - i. e. the machine and system po-
tential - is now also used as a measurement
electrode. The evaluation takes place withremote electronics.KXS sensors can be used for levelmonitoring of liquids, pastes or bulk
material, including measurement through
non-metal partitions. Furthermore as limit
switches, contactless position switches for
monitoring and positioning, as a pulse
generator for counting tasks and for many
other applications. Extreme series. Position control of transported tins

glue with capacitive sensors of the
KXS- Extreme series Overflow protection of casts, forexample for plastic
industrial lenses for
glasses with capacitive sensors of
the KXS- Extreme series The capacitive filling
level measuring
systems (KFS/KFA; KFX) operate
according to the three-electrode
principle. Here the container or anadditional electrode serves as a
counter-electrode to the probe elec-
trodes. For this reason it is essenti-
al with this system that the container
is of a conductive material or a
„substitute electrode“ is fixed to the
container wall, e.g. copper foil.Filling level measurements incontainers or tubes up to 5 m in
diameter are possible. Maximum
