Kotron^® RF
Sensing Probes
DESCRIPTION
Kotron RF Capacitance sensing probes are available in
many different configurations to handle a wide variety of
application conditions.
The sensing probes in this brochure can be combined
with Kotron level switches and transmitters.

TECHNOLOGY
The amount of capacitance developed in any application
is affected by three variables:
• size (surface area) of the probe;
• distance from the probe to its ground;
• dielectric of the medium it is measuring.
Considering that the probe’s mounting position is fixed,
and the dielectric constant of the process media is stable,
then the amount of capacitance developed is directly pro-
portional to the level of the process media on the probe.
Increasing the surface area (diameter) of the probe
and/or decreasing the distance between the probe and its
ground reference will increase the capacitance gain.
