RIGID PROBES
• Available as bare probe or insulated probe
• Maximum process temperature:
+1000° F (+540° C) – bare probe
+400° F (+200° C) – insulated probe
• Maximum process pressure 5,000 PSIG (345 bar)
• Lengths up to 234 inches (6 meters)
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;
• Bare probes can be cut to length in the field
• distance from the probe to its ground;
• Wetted materials include 316/316L SS, Hastelloy® C,
Teflon® (TFE), Halar® (ECTFE) and Kynar® (PVDF)
• Ceramic seals for High Temperature/High Pressure
designs
FLEXIBLE PROBES
• Available as bare probe or insulated probe
• Maximum temperature:
+650° F (+345° C) – bare probe
+285° F (+140° C) – insulated probe
• 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 proportional 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.
• Lengths up to 150 feet (45 meters)

Probes are an essential component of the RF Capacitance
measurement system. They are critical in development of
the proper “capacitor” for reliable level measurement. As
importantly, the probe becomes part of the process seal
of the vessel; its reliability is crucial. With the development of the Magneseal probe, Magnetrol has taken strides
to further ensure this reliability.
The Magneseal probe offers the following advantages:
1. A sophisticated compression seal exerts radial pressure
between the center rod and the mounting nut yielding
bulletproof sealing up to 3000 psig (205 bar).
2. Spring washers maintain the seal particularly during
varying temperature and pressure that can degrade
other process seals.
3. The Teflon® (TFE) probe insulation is
heat-treated which forms the material
tight to the probe rod. This process
yields better linearity and eliminates
“stress-relieving” (elongation) of the
material at elevated temperatures.
4. Stability of the outer jacket is maintained by the end of the probe barb
which further secures the insulating
jacket.
The Magneseal design ensures reliability
long after initial installation.

Non-conductive (dielectric less than 10 or conductivity
less than 10 µsiemens/cm)
Hydrocarbons, solvents, and bulk solids typically fall into
the category of non-conductive media. Initially, when the
vessel is empty, the dielectric constant is 1 (air). As the
media level rises, the dielectric of the media replaces the
air, thus causing the capacitance to increase. This
increase is linear with the level increase. A bare probe is
usually the best choice for this application.

(insulating medium)
Bare metal

Metal vessel wall
(ground reference)
Conductive (dielectric greater than 10 or conductivity
greater than 10 µsiemens/cm)
Conductive media in conjunction with a bare probe will
result in an electrical “short”, causing a transmitter to
indicate a high level or a switch to change state. The
solution is to use an insulated probe constructed of
Teflon®, Kynar®, or Halar®. The conductive media creates an
electrical connection between a metal vessel wall and the
probe insulation. Like the non-conductive application,
the distance between the probe and ground, and the
probe diameter is fixed. Instead of measuring the dielectric of the media, we are measuring the dielectric of the
probe insulation which is covered by the media.

Probe selection is the most critical part of applying an
RF Capacitance device for a given application. The goal
is to select the probe that will give the optimum capacitance change per unit level change (pF/inch). The first
step in selecting an RF probe is determining the correct
configuration for your application. The following guidelines will assist you in this selection.
1. Use bare probes for non-conductive liquids.
where the probe will be mounted more than 12" (30 cm)
from the vessel wall, or when measuring any liquid in
non-metallic vessels. The stillwell probe is the most
common. If the application requires “no metal” in the
process; or, if the liquid is too viscous for a stillwell,
use the reference rod probe. The reference wire probe
should only be used in clean, conductive,
non-coating applications.
2. Use insulated probes for conductive liquids. If you are
uncertain about the conductivity value, use an insulated
probe. Teflon® has the widest temperature range and
material compatibility. Kynar® will maximize the
capacitance change.
4. Use a flexible (cable) probe when the measurement
range is greater than 10 feet (3 meters). Rigid (rod)
probes are available up to 234 inches (6 meters) in
length, but they are sometimes difficult to handle and
can be damaged during installation.
3. Use a probe with an integral ground reference
(Reference Probe) when measuring non-conductive
fluids in horizontal vessels, non-conductive liquids
5. Use an inactive sheath probe when mounting
horizontally through a nozzle.
R I G I D
P R O B E S
Rigid probes consist of a process connection, probe rod,
and the seal. The rod may take many forms, depending
on the application. The following is a description of some
of the more common rigid probe styles:
Bare probes
Bare rod probes are typically used in non-conductive
process media with a dielectric value less than 10
or a conductivity value less than 10 µsiemens/in.
Capacitance is measured from the probe through the
process media to the vessel wall.
Insulated probes
Insulated rod probes are used in conductive process media with a dielectric
value greater than 10 or a conductivity
value greater than
10
µsiemens/in.
Capacitance is typically measured from
the probe rod through the insulation to
the process media, which is at the same
potential as the vessel wall for conductive
media. Probes are insulated with Teflon®,
Halar®, or Kynar®. When you are uncertain
about the dielectric constant of your
process media, insulated probes are a
wise choice.
Inactive sheath probes
An inactive sheath is a metallic tube that is tightly coupled to the insulation on the probe rod and attached
to the process connection. The sheath “deadens” the
portion of the probe covered. It is used when a
false capacitance could be developed by interference, such as:
• Collection of debris in a nozzle when
the probe is horizontally mounted
• Falling process media entering the vessel
• Use with Retractable Probe Assembly (Hot Tap)

Bent probes
Bent rod probes have a variety of uses. They can provide vertical configurations when only side mounting
is available. They can also provide horizontal configurations when only top mounting is available. When
top mounted, the horizontal section of the probe can
be used to create an extremely stable setpoint by
developing a very large capacitance change with a
small level change.

Sanitary
fitting
Reference wire
A reference wire is spirally wrapped around
an insulated probe to provide a “ground”
reference where none exists. It must be
used selectively: clean, conductive, and low
viscosity processes only.
Reference rod probes
An insulated reference rod is mounted parallel with the sensing probe. It is typically
used with corrosive process media in nonmetallic vessels where no metal can be
introduced to the process.
Sanitary probes
These probes consist of Teflon® (TFE)
insulated rods with a Tri-clover style
process connection and are certified
by 3A.
GUARDED PROBES
REFERENCE PROBES
This classification covers probes that supply the “second
plate of the capacitor” in non-metallic vessels, or linearize
an existing reference (i.e. horizontal cylindrical vessels).
There are three types of referenced probes offered:
Stillwell probes
A stillwell is a metallic tube into which a probe is
inserted. It can be used to minimize the effect of turbulence in a vessel and increases the capacitance
gain by bringing the ground reference closer to the
probe. Stillwell probes are recommended for vessels
with agitators.

Guarded probes are only used for switch function in
applications where buildup can occur. The guarded
probes require additional coating rejection circuitry and
can only be used with the following Kotron switches:
Model 810, Model 811, and Sentinel Model 822.
The guarded probe can be cut to length but requires a
minimum of 4 inches (100 mm) below the lower probe
insulator.

Insulated flexible and bare flexible probes
Rigid probes longer than 10 feet (3 m) are difficult to
install and to physically move in the field. Flexible
probes are the ideal solution for measuring ranges
from 10 feet (3 m) up to 150 feet (45 m).
Insulated flexible probes can be used with either conductive or non-conductive media. Bare flexible
probes can only be used with non-conductive media.
Always verify that the selected electronics is powerful
enough to operate at these longer distances.

mine the proper probe/electronics choice
for any given application. To use the
18
graphs, follow the steps below.

1. Determine the dielectric of the
process medium being measured.
If the dielectric is unknown, use a
dielectric of 2 for non-conductive
12 4.8
media such as hydrocarbons or dry
media, and a dielectric value of 80
for water based, conductive liquids
(dielectric values are along the X axis).
2. Choose a probe. Because more than
one probe will usually work, consider
the other application parameters such
as temperature, pressure, material compatibility, etc.
3. Find the graph which covers the
chosen probe. Choose the curve on the
graph which most closely relates to
your particular application.
4. Using the chosen curve, determine the
amount of pF/inch or pF/centimeter
your application will develop (values
are on Y axis).
5. Multiply the pF/inch value by the transmitter span needed in the application.
6. Compare total capacitance generated
by the probe against the needed zero
and span of the Kotron electronics to
be used.

2.00 pF/inch × 72 in = 144 pF
The total capacitance is enough to meet the 50 pF minimum
span of the electronics.
These charts are meant as an application aid; actual values may differ
slightly. Always provide a 10% margin of error to ensure satisfactory
performance.
These curves represent the probe located in the center of the vessel.
If the probe is near one wall of a large vessel, multiply the distance
from the vessel wall by 2 (to develop a diameter), choose the closest
curve in the chart to your application, and then multiply the resultant
pF value × 78%. This will account for the probe not being totally surrounded by the ground reference.
