Level Transmitter
D E S C R I P T I O N
The Eclipse® Model 706 High Performance Transmitter is a
loop-powered, 24 VDC level transmitter that is based
upon the proven and accepted technology of Guided
Wave Radar (GWR). Encompassing a number of signifi-
cant engineering accomplishments, this leading edge level
transmitter is designed to provide measurement perform-
ance well beyond that of many of the more traditional
technologies.
Utilizing “diode switching” technology, along with the
most comprehensive probe offering on the market, this
single transmitter can be used in a wide variety of appli-
cations ranging from very light hydrocarbons to water-
based media.
The innovative angled, dual compartment enclosure is
now a common sight in the industry. This enclosure, first
brought to the industry by Magnetrol® in 1998, is angled
to maximize ease of wiring, configuration, and viewing of
the versatile graphic LCD display.
One universal Model 706 transmitter can be used and
interchanged with all probe types, and offers enhanced
reliability as it is certified for use in critical SIL 2 hardware
safety loops.
The ECLIPSE Model 706 supports both the FDT/DTM and
Enhanced DD (EDDL) standards, which allow viewing of
valuable configuration and diagnostic information such as
the echo curve in tools such as PACTware™, AMS Device
Manager, and various HART® Field Communicators.

IN TERFA CE MEA SUREMENT
The ECLIPSE Model 706 is capable of measuring both an
upper liquid level and an interface liquid level. As only a
portion of the pulse is reflected from a low dielectric upper
surface, some of the transmitted energy continues down
the GWR probe through the upper liquid. The remaining
initial pulse is again reflected when it reaches the higher
dielectric lower liquid. It is required that the upper liquid
has a dielectric constant less than 10, and the lower liquid
has a dielectric constant greater than 15. A typical interface
application would be oil over water, with the upper layer
of oil being non-conductive (εr ≈ 2.0), and the lower layer
of water being very conductive (εr ≈ 80). The thickness of the
upper layer could be as small as 2" (50 mm) while the max-
imum upper layer is limited to the length of the GWR probe.
PRINCIPLE OF OPERATION
ECLIPSE Guided Wave Radar is based upon the technology
of TDR (Time Domain Reflectometry). TDR utilizes pulses
of electromagnetic energy transmitted down a wave guide
(probe). When a pulse reaches a surface that has a higher
dielectric constant than the air (εr = 1) in which it is trav-
eling, a portion of the pulse is reflected. The transit time
of the pulse is then measured via high speed timing
circuitry that provides an accurate measure of the liquid
(or solids) level. The amplitude of the reflection depends
on the dielectric constant of the product. The higher the
dielectric constant, the larger is the reflection. Bulk Solid Level

EMULSION LAYERS
As emulsion layers, also called “rag layers,” can decrease
the strength of the reflected signal in an interface appli-
cation, GWR transmitters are typically recommended for
applications that have clean, distinct layers.
However, the ECLIPSE Model 706, with its powerful
internal measurement algorithms, will tend to detect the
top of an emulsion layer. Contact the factory for applica-
tion assistance regarding emulsion layers in your specific
application.
SATURATED STEAM APPLICATIONS
(Boilers, Feedwater Heaters, etc.)
As the temperature of a saturated steam application
increases, the dielectric constant of the steam vapor space
also increases. This increase in vapor space dielectric
causes a delay in the GWR signal propagation as it trav-
els down the probe, causing the liquid level to appear
lower than actual.
The ECLIPSE Model 706 transmitter and Model 7yS Coaxial
Steam probe provide a unique solution to this application.
The effects of the changing steam conditions can be
compensated for by utilizing a mechanical steam target
placed inside and near the top of the Model 7yS coaxial
probe.
NOTE: The measurement error associated with this
propagation delay does depend on temper-
ature and is a function of the square root
of the vapor space dielectric constant. For
example, with no compensation, a +450 °F
(+230 °C) application would show a level
error of about 5.5%, while a +600 °F
(+315 °C) application would show an error
approaching 20%!
Knowing exactly where the target is located at room temper-
ature, and then continuously monitoring its apparent
location, the vapor space dielectric can be back-calculated.
Knowing the vapor space dielectric, accurate compensa-
tion of the actual liquid level reading is accomplished.
This is a patented technique with two US Patents
(US 6642801 and US 6867729) issued for both the mechan-
ical target concept and the associated software algorithm.
Contact the factory for additional information relating to
saturated steam applications.
OVERFILL CAPABILITY
Although agencies like WHG or VLAREM certify Overfill
proof protection, defined as the tested, reliable operation
when the transmitter is used as overfill alarm, it is as-
sumed in their analysis that the installation is designed in
such a way that the vessel or side mounted cage cannot
physically overfill.
However, there are practical applications where a GWR
probe can be completely flooded with level all the way up
to the process connection (face of the flange). Although
the affected areas are application dependent, typical GWR
probes have a transition zone (or possibly dead zone) at
the top of the probe where interacting signals can either
affect the linearity of the measurement or, more dramati-
cally, result in a complete loss of signal.
While some manufacturers of GWR transmitters may use
special algorithms to “infer” level measurement when this
undesirable signal interaction occurs and the actual level sig-
nal is lost, the ECLIPSE Model 706 offers a unique solution
by utilizing a concept called Overfill Safe Operation.
An Overfill safe probe is defined by the fact that it has
a predictable and uniform characteristic impedance all the
way down the entire length of the waveguide (probe).
These probes allow the ECLIPSE Model 706 to measure
accurate levels up to the process flange without any non-
measurable zone at the top of the GWR probe.
Overfill safe GWR probes are unique to ECLIPSE GWR,
and coaxial probes can be installed at any location on the
vessel. Overfill safe probes are offered in a variety of
Coaxial and Caged designs.

With one basic ECLIPSE Model 706 transmitter that oper-
ates with all probes, choosing the proper Guided Wave
Radar (GWR) probe is the most important decision in the
application process. The probe configuration establishes
fundamental performance characteristics.
All ECLIPSE Model 706 probes can be described by three
basic configurations:
• Coaxial
• Twin flexible cable
• Single element (rigid rod or flexible cable)
Each of these probe configurations has specific strengths
and weaknesses. Although there can be overlap, and dif-
ferent probes can certainly be used in similar applications,
it is important to understand their basic differences so that
one can choose the probe type that will offer optimal
performance.
The descriptions below are facts relating to the physics of
GWR technology and are not specific to the ECLIPSE
Model 706.
COAXIAL PROBES
The coaxial probe is the most efficient of all GWR probe
configurations and should be the first consideration in all
applications. Analogous to the efficiency of coaxial cable,
a coaxial probe allows almost unimpeded movement of
the high frequency pulses throughout its length.
The electromagnetic field that develops between the inner
rod and outer tube is completely contained and uniform
down the entire length of the probe. See Figure 1. This means
that the coaxial probe is immune to any proximity affects
from other objects in the vessel, and therefore, in essence,
it can be used anywhere that it can mechanically fit.
The efficiency and overall sensitivity of a coaxial config-
uration yields robust signal strength, even in extremely
low dielectric (εr ≥1.4) applications. The sensitivity of this
“closed” design, however, also makes it more susceptible
to measurement error in applications that can have coat-
ing and buildup.
All ECLIPSE Model 706 coaxial probes are Overfill Safe as
standard, by design.
BASI C —FOR CLEAN LIQUIDS
The basic 0.875" (22.5 mm) diameter coaxial GWR probe
is only recommended for use in clean applications or spe-
cial applications such as saturated steam. Teflon®, PEEK,
or alumina spacers centering the inner rod within the
outer tube are located at 24" (60 cm) intervals, resulting in
a perfect characteristic impedance along the entire length
of the probe.
This probe is recommended in applications with viscosities
up to 500 cP (mPa.s) maximum.
ENLARGED—FOR DIFFICULT LIQUIDS
The standard Enlarged 1.75" (45 mm) or 1.93” (49mm)
diameter coaxial GWR probes can be generally used for
most applications. They can be installed directly into the
tank as well as into bypass cages, stillwells or bridles.
The robust construction reduces the number of spacers
required, allowing the probe to be used in applications
where higher risk of buildup exists. To further reduce the
possibility of media buildup, the use of a single bottom
spacer is recommended up to probe lengths of 100 inches
(2.54 meters). The overall sensitivity and performance of
an enlarged coaxial GWR probe is identical to a standard
coaxial GWR probe, but it offers the very important ad-
vantage that it can be used in applications with viscosities
up to 2,000 cP (mPa.s).

5
CAGED—FOR DIRTY LIQUIDS
Unique to MAGNETROL, the Caged GWR probe is a single
rod probe which uses an existing or new cage, bridle, or
stillwell as the second conductor to re-create the same sig-
nal propagation as a coaxial GWR probe. Caged GWR
probes are designed for 2" (DN50), 3" (DN80) or 4"
(DN100) diameter metal chambers, and utilize a specially
designed impedance matching section that results in the
same overall characteristic impedance of a coaxial style
GWR probe.
Caged GWR probes offer the same sensitivity and perform-
ance as coaxial GWR probes, but the single conductor
design allows it to be used in applications with viscosities
up to 10,000 cP (mPa.s).

OPTIONAL FLUSHING
CONNECTION
The maintenance of coaxial GWR probes in applications
suffering from buildup or crystallization can be signifi-
cantly improved by using an optional flushing connection.
This flushing connection is a metal extension with a port
welded above the process connection. The port allows
the user to purge the inside of the coaxial GWR probe
during routine maintenance.
Note: The best approach to eliminate the effects of
condensation or crystallization is to install
adequate insulation or heat tracing (steam or
electrical). A flushing connection is no sub-
stitute for proper maintenance, but will help
to reduce the frequency of the intervention.

ECLIPSE Model 706 probes containing a glass ceramic
alloy process seal (Models 7yD, P, J, L, M and N) are avail-
able with an optional annunciator fitting. The use of this
fitting complies with the Dual Seal requirements of
ANSI/ISA-12.27.01-2011, titled “Requirements for Process
Sealing between Electrical Systems and Flammable or
Combustible Process Fluids,” which require the incorpo-
ration of a method that indicates or annunciates a primary
seal failure (e.g., visible leakage, an audible whistle, or
other means of monitoring).

The relationship of the Twin Cable probe design to a
coaxial probe design is similar to that of older, twin-lead,
antenna lead-in to modern, coaxial cable. 300-ohm twin-
lead cable simply does not have the efficiency of 75-ohm
coaxial cable, making the parallel conductor design less
sensitive than the concentric coaxial. See Figure 2. This trans-
lates into Twin Cable GWR probes having the ability to
measure dielectrics down to εr ≥1.7.
Heavy bridging of material between the cables across the
FEP coating can cause improper measurement and should
be avoided.
Figure 2 also shows that, although most of the electromag-
netic field develops between the two cables, there is also
some peripheral energy that expands outward, making the
Twin Cable probe more sensitive to proximity effects of
objects located immediately around it. For that reason, it is
recommended to keep the active element of the Twin Cable
probe at least 1 inch (25 mm) away from metal objects.
SINGLE R OD PROBES
Single element GWR probes act quite differently than both
coaxial and twin cable designs. With only one conductor
to work with, the pulses of energy develop between the
single rod probe and the mounting nut or flange. In other
words, the pulse propagates down and around the rod as
it references its ground at the top of the tank.
The energy and efficiency of the pulse are directly related
to how much metallic surface exists around it at the top of
the vessel. This metallic surface at the top of the probe is
called the “launch plate.” The larger the launch plate, the
more efficient the signal propagation down the probe.
Figure 3 shows the single element design and how the
electromagnetic pulse effectively expands into a teardrop
shape as it propagates away from the top of the tank (the
inherent ground reference). This single element configu-
ration (rod or cable) is the least efficient of the three probe
types, but can still operate with a minimum dielectric
detection of approximately εr > 1.7 in an open, non-
metallic vessel.
However, this dielectric constant performance improves
considerably (εr > 1.4) when the single rod probe is installed
in a metal cage/bridle, or mounted 2–6" (50–150 mm)
away from a metal tank wall. Because the design is
“open,” it exhibits two strong tendencies:
• It is the most forgiving of coating and buildup. (The
PFA-insulated probe is the best choice for severe
buildup and coating).
• It is most affected by proximity issues.
It is important to note that a parallel metal wall INCREASES
the performance of a single rod probe while a singular,
metal object protruding out near the probe may be improp-
erly detected as a liquid level.
These tendencies are application/installation dependent.
Therefore, by properly matching the single rod probe to a
cage/chamber, the ECLIPSE Model 706 broad offering of
caged probes combines the performance/sensitivity ad-
vantages of a coaxial probe and the viscosity immunity of
a single rod probe. The Caged Probes are Overfill Safe by
design, can be used in interface and other difficult, low
dielectric applications, and are unique to MAGNETROL
and the ECLIPSE Model 706.

ECLIPSE has proven to be the ideal replacement for exist-
ing torque tube transmitters. In numerous applications
worldwide, customers have found the performance of
ECLIPSE Guided Wave Radar transmitters to be superior to
that of antiquated torque tube transmitters.
There are several benefits to using the ECLIPSE Model 706
as a replacement for torque tube transmitters:
• Cost:
The cost of a new Model 706 transmitter cost is com-
parable to rebuilding an aging torque tube.
• Installation:
No field calibration is necessary. The Model 706 trans-
mitter can be configured in minutes with no level move-
ment. (Complete factory pre-configuration is available,
which can further decrease the installation effort).
• Performance:
The ECLIPSE Model 706 is unaffected by changes in
specific gravity and has no moving parts that can wear
and lose tolerance.
• Ease of replacement:
Proprietary and standard ANSI flanges are offered on all
ECLIPSE Model 706 probes so existing chamber/cages
can be used.
In order to match the proper ECLIPSE transmitter with the
proper external cage, consider the following:
• Type of application:
Use the proper GWR probe for the application, see
pages 7 and 10 through 16.
• Overfill proof:
For optimum performance, use an Overfill-safe probe
in all chamber applications.
Note: “Overfill” occurs when the level rises above
the maximum range of operation. Some
GWR probes may provide erroneous output
in this zone unless an optimal, impedance-
matched design is used.
• Minimum Cage Size:
• Coaxial or Caged Coaxial probes: 2" minimum
• Enlarged Coaxial probes: 3" minimum
• Twin Cable probes: 4" minimum
Recommended probe length for replacing displacer transmitters
The table below helps to define the GWR probe length for the most common displacer transmitters.
Refer to the proprietary flange selection guide.

chamber is a self-contained cage designed for use with our top mounting level transmitters or
switches. Quality construction and a wide selection of configurations make this cage an ideal means
of utilizing the power of Guided Wave Radar without mounting directly into the process vessel.

MAGNETROL chambers are available with a wide variety
of options, and can be manufactured to comply with var-
ious regulations such as:
• Commercial Design
• ASME B31.1 Design Code
• ASME B31.3 Design Code
• NACE Design Code
• PED
Some Model 706 probes can be installed into chambers
as small as 2". When a new chamber is required, it can be
ordered together with a factory pre-configured Model 706
for a true “plug and play” installation.
For example:
A standard Model 706-511A-310 explosion-proof trans-
mitter with a Model 7AG-4300-A10-00-021 Caged probe
can be used in a 2" chamber. A typical chamber Model
Number would be:
F21-4A2D-014
Refer to MAGNETROL Sales Bulletin 41-140 for details on
chamber Model Numbers and additional options.

M O U N T I N G C O N S I D E R A T I O N S
For Rigid Models 7yF, M, N and Flexible Models 7y1,
2, 4 and 6
1. Turbulence
The bottom of rigid probes should be stabilized if
turbulence will cause a deflection of more than
3" (75 mm) at the end of a 10' (3 m) length. The probe
should not make contact with metal.
2. Nozzle
Single rod performance in nozzles can be improved
by ensuring the following:
• Nozzle must be 2" (50 mm) or larger diameter.
• Nozzle should be as short as possible.
• Nozzle inside diameter (A) should be ≥ to nozzle
height (B).
• If this is not the case, adjustments to
BLOCKING DISTANCE and/or SENSITIVITY
parameters may be required.
3. Metallic (conductive) obstructions in tank.
Although it depends on the transmitter configuration,
objects in the proximity of the probe can cause erro-
neous readings. Please refer to the table below for
guidelines, but please contact the factory with any
questions as the distances shown can be reduced with
the use of PACTware™.
Note: A metal stillwell/cage of max. 6"/DN150
size or a metal tank wall parallel to the
probe within 6" (150 mm) will allow the
unit to operate accurately in media with di-
electrics down to εr 1.4.
4. Non-metallic vessels
A metal flange is highly recommended for optimum
performance in plastic vessels.
NOTE: Singe rod probes must be used in metallic
vessels or stillwell to maintain CE noise immunity.
Shutdown /Overfill protection
Special consideration is necessary in any shutdown/
overfill protection application where single rod GWR
probes are used. To ensure proper measurement, use
Overfill Capable single rod probes, such as the Model
7yG, L, or J Caged probes in the appropriate cage/
chamber/stillwell.
Mounting Considerations for Single Flexible probes
measuring Bulk Solids
The Model 7y2 Bulk Solid probe is designed for a 3000 lb.
(1360 kg) pull-down force for use in applications such as
sand, plastic pellets, and grains.
• To reduce excessive stresses on the top of the
vessel, do not secure the metal probe weight to the
bottom of the vessel.
• Mount the probe at least 12 inches from the wall.
The ideal location is 1
⁄4 to 1
⁄2 the diameter to average
the angle of repose.
Distance to probe Acceptable objects
< 6" (150 mm) Continuous, smooth, parallel,
conductive surface (e.g. metal
tank wall); probe should not
touch tank wall
> 6" (150 mm) < 1"/DN25 diameter pipe and
beams, ladder rungs
> 12" (300 mm) < 3"/DN80 diameter pipe and
beams, concrete walls

For Models 7y7
1. Turbulence
The bottom of Twin Flexible probes can be secured
to the bottom of the vessel by using the TFE weight
at the bottom of the probe. The TFE weight has a
1
⁄2" (13 mm) hole that can be utilize to “u-bolt” the
probe to the bottom of the vessel.
The probe should not make contact with metal.
2. Nozzle
Twin Flexible probe performance in nozzles can be
improved by ensuring the following:
• Nozzle should be 3" (DN80) diameter or larger.
• Nozzle should be as short as possible.
3. Metallic (conductive) obstructions in tank.
Mount the Twin Flexible probe more than 1" (25 mm)
from any metallic object/vessel wall.
Mounting Considerations for Twin Flexible Model 7y5
probes measuring Bulk Solids:
The Model 7y5 Bulk Solid probe is designed for a 3000 lb.
(1360 kg) pull-down force for use in applications such as
sand, plastic pellets, and grains.
• To reduce excessive stresses on the top of the
vessel, do not secure the metal probe weight to the
bottom of the vessel.
• Mount the probe at least 12 inches from the wall.
The ideal location is 1
⁄4 to 1
⁄2 the diameter to average
the angle of repose.

A U R O R A ®
C H A M B E R
The Orion Instruments® Aurora® is the patented combi-
nation of the ECLIPSE Guided Wave Radar transmitter and
a Magnetic Level Indicator (MLI). The integration of these
two independent technologies provides excellent redun-
dancy. A custom float positioned within the AURORA
chamber travels up and down following level changes.
The float contains an internal group of magnets that are
“coupled” with magnets in the flags of the visual indica-
tor mounted on the outside of the chamber. As the float
moves, the flags rotate to expose the color of their oppo-
site side. The position where the flag’s color changes cor-
responds to a point on the measuring scale indicating true
level. In addition to this external visual indicator oper-
ated by the AURORA internal float, the ECLIPSE
Model 706 transmitter reflects electromagnetic radar pulses
directly off the liquid surface providing a real-time con-
tinuous level output.
Refer to Orion Instruments® Sales Bulletin ORI-138 for
details and additional options on AURORA chambers.
Regardless of whether a standard chamber or AURORA
chamber is being used it is important to remember:
• Ensure that the Model 706 probe extends at least 4"
(100 mm) past the lower process connection of the
chamber
• Utilize Overfill-capable probes for optimal GWR
performance.
