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 r eflected 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).
Figure 2-1. Measurement
Principle.
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.

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 3300 transmitters suitable for a wide range of
applications:

SYSTEM ARCHITECTURE
Figure 2-4. System architecture.
The Rosemount 3300 Series Radar Transmitter is loop-powered which
means it uses the same two wires for both power supply and output signal.
The output is a 4-20 mA analog signal superimposed with a digital HART
signal.
By using the optional HART Tri-loop, it is possib le to convert the HAR T signal
to up to three additional 4-20 mA analog signals.
With the HART protocol it is possible to use multidrop configuration. In this
case communication is restricted to digital since current is fixed to the 4 mA
minimum value.
The transmitter can be connected to display Ros em o un t 75 1 Fi eld Signal
Indicator or it can be equipped with an integral display.
The transmitter can easily be configured by using a Field Communicator or a
PC with the Radar Configuration Tool software. Rosemount 3300 Series
transmitters are also compatible with the AMS Suite software which also can
be used for configuration.
For HART communication a minimum load resistance of 250 Ohm within the
loop is required.

Dead Zones The measuring range depends on probe type and properties of the product.
The Upper Dead Zone is the minimum measurement distance between the
upper reference point and the product surface. The Upper Dead 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 Dead
Zone. The Lower Dead Zone also varies depending on probe type and
product.

PROCESS CHARACTERISTICS
The Rosemount 3300 Series has a high sensitivity due to its adva nced signa l
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.
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 choose a suitable probe:
Table 2-3. Probe type guide for
different product viscosity
Coating not recommended Thin coating allowed, but no
(1) Consult factory if agitation/turbulence and high viscous products.
(2) HTHP and HP single probes should be used with precaution in viscous or crystallizing media. Cooling
Maximum measurement error due to coating is 1-10% depending on probe
type, dielectric constant, coating thickness and coating height above product
surface.

bridging
of high temperature vapor in the upper part of the probe may lead to condensation and deposition
that blocks the measurement signal.
(1)(2)
Bridging 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, will
cause 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.
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.
Vapor In some applications, 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.

The maximum measuring range differs depending on application according
to:

• Media with higher dielectric constant (ε

r
allows a longer measuring range.
• A calm surface gives better reflection than a turbulent surface. For a
turbulent surface the measuring range might be reduced.
• Surface foam and particles in the tank atmosphere are also
circumstances that might affect measuring performance.
• Coating/contamination can reduce the measuring range.
• Disturbing EMC environment in tank.

Interface Rosemount 3302 is the ideal choice for measuring the interface of oil and
water, or other liqui ds with significant dielectric differences. It is also possible
to measure interface with a Rosemount 3301 in applications where the prob e
is fully immersed in the liquid.

3302 and a Rosemount 3301

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 kn own. The Radar
• The dielectric constant of the upper product must have a lower
• The difference between the dielectric constants for the two products
• Maximum dielectric constant for the upper product is 10 for the coaxial

Figure 2-7. Reduction of
maximum measuring range for

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), and 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 2-7 on page 2-10.
However, chara cteristics 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.
Heating Coils, Agitators
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.
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.

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 3300 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.
