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.

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.
T E C H N O L O G Y
The amount of capacitance developed in any application
is affected by three variables:
•
size (surface area) of the probe;
A P P L I C A T I O N S
•
Clean or dirty liquids
•
Viscous liquids
•
Light slurries
•
High temperature/pressure liquids
•
Foods and beverages
•
Hydrocarbons and solvents
•
Corrosives, acids, and caustics
