TECHNOLOGY
The amount of capacitance developed in any application is affected by three variables: • size (surface area) of the 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.
APPLICATIONS
• Clean or dirty liquids • Viscous liquids • Light slurries • High temperature/pressure liquids • Foods and beverages • Hydrocarbons and solvents • Corrosives, acids, and caustics
• Ceramic seals for High Temperature/High Pressure designs

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.
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.
PROCESS
MEDIA
GUIDELINES
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. 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.

SELECTION
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. 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. 5. Use an inactive sheath probe when mounting horizontally through a nozzle.
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. 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. 3. Use a probe with an integral ground reference (Reference Probe) when measuring non-conductive fluids in horizontal vessels, non-conductive liquids
RIGID
PROBES
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)
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.

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.
L1
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.
L2
Sanitary fitting
Sanitary probes These probes consist of Teflon® (TFE) insulated rods with a Tri-clover style process connection and are certified by 3A. GUARDED PROBES 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.
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.

FLEXIBLE
PROBES
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.

EXTENSION
The heat dissipation graph, at left, depicts the maximum temperatures at which the extension can be used effectively. 1. Determine the maximum process temperature in the application and locate on X axis. 2. Determine the maximum ambient temperature surrounding the heat extension and locate on the Y axis. 3. If the intersecting point on the graph is within the shaded area the heat extension will dissipate enough heat to keep the electronics temperature below +160° F (+70° C). NOTE: The heat extension may be used with all rigid probe configurations and flexible probe configuration 8A2-AA1A-0XX. The heat extension can not be used with guarded probes.

The following pages contain capacitance gain graphs which can be used to determine the proper probe/electronics choice for any given application. To use the 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 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.
