Worldwide level and flow solutions GUIDELINES FOR SELECTING A CORRECT PROBE CONFIGURATION Probe selection is the most critical part of applying an R.F. 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/cm). The first step in selecting an R.F. 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 not sure about the conductivity value, use an insulated probe. Teflon has the widest temperature range and material compatibility. Kynar will maximize the capacitance change. (Use Kynar where possible.) 3. Use a probe with an integral ground reference (Reference Probe) when measuring non-conductive fluids in horizontal tanks, non-conductive liquids where the probe will be mounted more than 30 cm (12") from the vessel wall, or when measuring any liquid in nonmetallic 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 3 m (10'). Rigid (rod) probes are available up to 6m (236") 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. Recommendation for continuous measurement (with Kotron 082 and 805). • For non-conductive media (dielectric < 10 or conductivity less than 10 µsiemens/cm) 0 % = min. 100 mm (4") above end of probe. • For conductive media (dielectric > 10 or conductivity greater than 10 µsiemens/cm) 0 % = min. 50 mm (2") above end of probe. PRINCIPLE OF OPERATION 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 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. Basic Considerations There are two types of process media: • Non-conductive (dielectric < 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. Air 2 Non-conductive (insulating) medium Bare metal probe Metal tank wall (ground reference) • Conductive (dielectric > 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 (this may be desirable depending upon the application). The solution is to use an insulated probe constructed of Teflon®, Kynar®, etc. The conductive media creates an electrical connection between the tank wall and the probe insulation. Like the non-conductive application, the distance between the probe and ground, and the probe diameter, is fixed. However, instead of measuring the dielectric of the media, we are measuring the dielectric of the probe where it is covered by the media. Insulated probe Conductive medium Conductive medium (ground reference) Metal probe rod Metal tank wall Probe insulation CAPACITANCE PICO FARAD (pF) GAIN GRAPHS 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. Since more than one probe will usually work, consider the other application parameters such as temperature, pressure, material compatability, etc. 3. Find the graph which covers the chosen probe. Choose the curve on the graph which most closely relates to your particular application (Stillwell, 10 cm, 30 cm, 60 cm, 120 cm and 240 cm tank dia.). 4. Using the chosen curve, determine the amount of pF/cm your application will develop (pF/cm values are on Y axis). 5. Multiply the pF/cm value by the total cm of probe needed in your application. 6. Compare total capacitance generated by probe against the needed zero and span of the Kotron electronics to be used.

Always give yourself at 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 tank, do the following: multiply the distance from the tank wall by 2 (to develop a diameter), choose the closest curve in the chart to your application, and then multiply the resultant pF value x 78 %. This will account for the probe not being totally surrounded by the ground reference. pF per cm (inch) 8.0 (20) Stillwell 7.2 (18) 6.4 (16) 5.6 (14) 4.8 (12) 4.0 (10) 3.2 (8) 2.4 (6) 1.6 (4) 0.8 (2) 0 (0) Tank diameter cm (inches) 10 (4) 30 (12) 60 (24) 120 (48) 240 (96) 1 2 3 4 5 6 7 Dielectric value of media 8 9 10 Example: Parameters: a.

The rod may take many forms, depending on the application. The following is a description of some of the more common rigid probe styles: 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/cm. Capacitance is typically rod measured from the probe rod through Probe Insulation the insulation to the process media, which is at the same potential as the tank wall for conductive media. Probes are insulated in Teflon, Halar® or Kynar. When you are uncertain about the dielectric constant of your process media, insulated probes are a wise choice. Inactive sheath An inactive sheath is a metallic tube that is tightly coupled to the insulation on the rod probe rod and attached to the process Probe Insulation 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 tank. Bent probe L1 Bent rod probes have a variety of uses. They can provide vertical configurations when only L2 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. REFERENCED PROBES This classification covers probes that can supply the “second plate of the capacitor” in non-metallic tanks, or linearize an existing reference (i.e. horizontal cylindrical tanks). There are two types of referenced probes offered: Stillwell A stillwell is a metallic tube, or pipe, into which a probe is inserted concentrically. 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. Reference wire A reference wire is spirally wrapped around an insulator probe to provide a “ground” reference where none exists. It must be used selectively: clean, conductive, and low viscosity processes only.

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. ➁ 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. ➀ 3. The Teflon (TFE) probe insulation is heat-treated which forms the material tight to the probe rod yielding better linearity eliminates “stress-relieving” (elongation) of the material at elevated temperatures. 4. Stability of the outer jacket is maintained by the end of probe barb which further secures the insulating jacket. ➂ The Magneseal design takes a giant step toward reliability; a probe design that can be installed and forgotten. ➃ DIMENSIONS in mm (Inches) guarded probe rigid probe Optional Mounting Flange Optional Mounting Flange 3/4" NPT 1G (1" BSP) flexible probe 150 (6.00) 3/4" NPT 1" NPT 1G (1" BSP) 19 (0.75) Insertion length Insertion length Optional Mounting Flange 3/4" NPT Optional Anchor Assembly 5 (0.1875) 6 (0.2500) 124 (4.87) 75 (2.95) 127 (5.00) 10 (0.375) 13 (0.50) - bare probe 16 (0.625) - insulated probe 19 (0.79) 34 (1.32) Optional Weight 11 CONNECTIONS Insertion length Insertion length Insertion length Welded flange ANSI / EN (DIN) Threaded NPT Threaded BSP Insertion length Insertion length DIN 11851 Tri-Clamp® QUALITY ASSURANCE - ISO 9001:2000 THE QUALITY ASSURANCE SYSTEM IN PLACE AT MAGNETROL GUARANTEES THE HIGHEST LEVEL OF QUALITY DURING THE DESIGN, THE CONSTRUCTION AND THE SERVICE OF CONTROLS.
