2.1 Theory of operation
The Rosemount 3300 Series Radar Transmitter is a smart, two-wire continuous level transmitter
that is based on Time Domain Reflectometry (TDR) principles. Low power nano-second-pulses
are guided along a probe immersed in the process media. When a pulse reaches the surface of
the material it is measuring, part of the energy is reflected back to the transmitter, and the time
difference between the generated and reflected pulse is converted into a distance from which
the total level or interface level is calculated (see below).
January 2015
The reflectivity of the product is a key parameter for measurement performance. A high
dielectric constant of the media gives better reflection and a longer measuring range. A calm
surface gives better reflection than a turbulent surface.

2.2 Application examples
The Rosemount 3300 Series Radar Transmitter program is suited for aggregate (total) level
measurements on most liquids, semi-liquids, and liquid/liquid interfaces.
Guided microwave technology offers highest reliability and precision which ensure
measurements are virtually unaffected by temperature, pressure, vapor gas mixtures, density,
turbulence, bubbling/boiling, low level, varying dielectric media, pH, and viscosity.
Guided wave radar technology in combination with advanced signal processing make the
Rosemount 3300 Series Transmitters suitable for a wide range of applications.

2.4 Process characteristics
The Rosemount 3300 Series has high sensitivity due to its advanced signal processing and high
signal to noise ratio, which makes it able to handle various disturbances. However, the following
circumstances should be considered before mounting the transmitter.
2.4.1 Coating
Coating on the probe should be avoided since the sensitivity of the transmitter may be
decreased leading to measurement errors. In viscous or sticky applications, periodic cleaning
may be required.
For viscous or sticky applications, it is important to select a suitable probe. For detailed
information on the maximum recommended viscosity and coating, see Table A-6 on page 131.
Maximum measurement error due to coating is 1-10% depending on probe type, dielectric
constant, coating thickness, and coating height above product surface.
2.4.2 Bridging
Section 2: Transmitter Overview
January 2015
Heavy coating that results in product bridging across the two probes for twin lead versions, or
between the pipe and the inner rod for coaxial probes, causes erroneous level readings and must
be prevented. Single lead probes are preferred in this case. If a twin lead probe is required,
regular cleaning may be necessary.
2.4.3 Foam
How well the Rosemount 3300 Series Radar Transmitter measures in foamy applications
depends upon the properties of the foam; light and airy or dense and heavy, high or low
dielectrics, etc. If the foam is conductive and creamy, the transmitter will probably measure the
surface of the foam. If the foam is less conductive, the microwaves will probably penetrate the
foam and measure the liquid surface.
2.4.4 Vapor
In some applications, such as ammonia, there is heavy vapor above the product surface that will
influence the level measurement. The Rosemount 3300 Series Radar Transmitter can be
configured to compensate for the influence of vapor.
2.4.5 Measuring range
The measuring range differs depending on probe type and characteristics of the application.
The values given in Table A-4 on page 128 can be used as a guideline for clean liquids.
The maximum measuring range differs depending on application according to:

2.4.6 Interface
Rosemount 3302 is the ideal choice for measuring the interface of oil and water, or other liquids
with significant dielectric differences. It is also possible to measure interface with a Rosemount
3301 in applications where the probe is fully immersed in the liquid.
Figure 2-3. Interface Measurement with a Rosemount 3302 and a Rosemount 3301 (Fully
Immersed Probe)
Reference Manual
00809-0100-4811, Rev DA
Coaxial, Rigid Twin, Flexible Twin and Rigid Single lead probes can be used for measuring
interfaces. The coaxial probe is the preferred choice for clean liquids and when the bridle is not
fully immersed. In applications with a fully immersed probe, the twin lead probes are
recommended for nozzle installations, and the rigid single lead probe is best for bridle
mounting.
For measuring the interface level, the transmitter uses the residual wave of the first reflection.
Part of the wave, which was not reflected at the upper product surface, continues until it is
reflected at the lower product surface. The speed of this wave depends fully on the dielectric
constant of the upper product.
If interface is to be measured, the following criteria have to be fulfilled:
The dielectric constant of the upper product must be known. The RCT software has a
built-in dielectric constant calculator to assist users in determining the dielectric
constant of the upper product (see “Dielectrics” on page 83).
The dielectric constant of the upper product must have a lower dielectric constant than
the lower product in order to have a distinct reflection.
The difference between the dielectric constants for the two products must be larger
than 10.
The maximum dielectric constant for the upper product is 10 for the coaxial probe, and
5 for twin lead probes.
The upper product thickness must be larger than 8 in. (0.2 m) for the flexible twin lead
probe, and 4 in. (0.1 m) for the rigid twin lead and coaxial probes in order to distinguish
the echoes of the two liquids.

The maximum allowable upper product thickness/measuring range is primarily determined by
the dielectric constants of the two liquids.
Target applications include interfaces between oil/oil-like and water/water-like liquids. For such
applications, the upper product dielectric constant is low (< 3) and the lower product dielectric
constant is high (> 20). The maximum measuring range is only limited by the length of the
coaxial and rigid twin lead probes.
For the flexible twin lead probe, the reduction of maximum measuring range (65 ft/20 m), can
be gained from Figure 2-4 on page 13.
However, characteristics varies widely between different applications. For other product
combinations, consult factory.

Emulsion layers
Sometimes there is an emulsion layer (mix of the products) between the two products which,
depending on its characteristics, will affect interface measurements.
Please consult factory for guidelines on how to handle emulsion layers.
The Rosemount 3300 Series Radar Transmitter is relatively insensitive to objects in the tank
since the radar signal is transmitted along a probe.
Avoid physical contact between probes and agitators as well as applications with strong fluid
movement unless the probe is anchored. If the probe can move within 1 ft (30 cm) away from
any object, such as an agitator, during operation, then probe tie-down is recommended.
In order to stabilize the probe for side forces, it is possible to hang a weight at the probe end
(flexible probes only) or fix/guide the probe to the tank bottom.

2.5.2 Tank shape
The guided wave radar transmitter is insensitive to the tank shape. Since the radar signal travels
along a probe, the shape of the tank bottom has virtually no effect on the measurement
performance. The transmitter handles flat or dish-bottom tanks equally well.
2.6 Components of the transmitter
The Rosemount 3300 Series Radar Transmitter has an aluminum transmitter housing which
contains advanced electronics for signal processing.
The radar electronics produces an electromagnetic pulse which is guided by the probe.
There are different probe types available for various applications: Rigid Twin Lead, Flexible Twin
Lead, Rigid Single Lead, Segmented Rigid Single Lead, Flexible Single Lead, and Coaxial.

2.7.1 Transition zones
The measuring range depends on probe type and properties of the product. The upper
transition zone is the minimum measurement distance between the upper reference point and
the product surface. The upper transition zone varies between 4 - 20 in. (0.1 and 0.5 m)
depending on probe type and product.
At the end of the probe, the measuring range is reduced by the lower transition zone. The lower
transition zone also varies depending on probe type and product.
Figure 2-6 illustrates how the measuring range is related to the transition zones.

For detailed information on transition zones for different probe types, see Tab le A- 4 on
page 128.
Note
Measurement accuracy is reduced in the transition zones. It may even be impossible to make
any measurements at all in those regions. Therefore, the 4-20 mA set points must be configured
outside the transition zones.

Explosions could result in death or serious injury.
Verify that the operating environment of the transmitter is consistent with the
appropriate hazardous locations certifications.
Before connecting a HART
®
-based communicator in an explosive atmosphere, make
sure the instruments in the loop are installed in accordance with intrinsically safe or
non-incendive field wiring practices.
In an Explosion-proof/flameproof installation, do not remove the transmitter cover
when power is applied to the unit.
Eliminate the risk of ESD discharge prior to dismounting the transmitter head.
Probes may generate an ignition- capable level of electrostatic charge under extreme
conditions. During any type of installation or maintenance in a potentially explosive
atmosphere, the responsible person should make sure that any ESD risks are
eliminated before attempting to separate the probe from the transmitter head.

Reference Manual
00809-0100-4811, Rev DA
Failure to follow safe installation and servicing guidelines could result in death or
serious injury.
Make sure only qualified personnel perform the installation.
Use the equipment only as specified in this manual. Failure to do so may impair the
protection provided by the equipment.
Do not perform any service other than those contained in this manual unless you are
qualified.
Process leaks could result in death or serious injury.
Make sure that the transmitter is handled carefully. If the Process Seal is damaged, gas
might escape from the tank when the transmitter head is removed from the probe.
High voltage that may be present on leads could cause electrical shock.
Avoid contact with leads and terminals.
Make sure the main power to the Rosemount 3300 Series Transmitter is off and the
lines to any other external power source are disconnected or not powered while wiring
the gauge.
Probes covered with plastic and/or with plastic discs may generate an ignition-capable
level of electrostatic charge under certain extreme conditions. Therefore, when the
probe is used in a potentially explosive atmosphere, appropriate measures must be
taken to prevent electrostatic discharge.
