RECYCLING/DISPOSAL
Recycling of equipment and packaging should be taken into consideration
and disposed of in accordance with local and national legislation/regulations.
THEORY OF OPERATIONThe Rosemount 5300 Series Radar Transmitter is a smart, two-wire
continuous level transmitter based on Time Domain Reflectometry (TDR)
principles. Low power nano-second-pulses are guided alon g an immersed
probe. When a pulse reaches the surface, 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, which calculates the total level or
interface level (see below).
Figure 2-1. Measurement
Principle.
The reflectivity of the product is a key parameter for measurement
performance. Media with a high dielectric constant gives better reflection and
a longer measuring range.

APPLICATIONSThe Rosemount 5300 Series Radar Tr ansmitter series is suite d for aggregate
(total) level measurements on most liquids, semi-liquids, solids, and
liquid/liquid interfaces.
Guided microwave technology offers the highest reliability and precision to
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 makes the Rosemount 5300 transmitters suitable for a wide r ange
of applications:
Figure 2-2. Application
examples
The Rosemount 5300 transmitter
works well in boiling conditions with
vapor and turbulence. If there are
disturbing objects in the vicinity of the
transmitter, the coaxial probe is
particularly suitable.

The Rosemount 5300 Series is well
suited for chamber applications, such
as distillation columns.

The Rosemount 5300 Series Radar T ransmitte r has an aluminum or st ainless

for signal processing. SST housing is preferred for harsh environment
applications, such as off-shore platforms or other location s where the housing
can be exposed to corrodents, such as salt solutions and caustics.
The radar electronics produces an electromag netic pulse that is guided by the
probe. It comes with flange, threaded or Tri-Clamp process connection.

ARCHITECTURE
Figure 2-5. HART system
architecture
The Rosemount 5300 Series Radar Transmitter is loop-powered, and 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
®
or FOUNDATION™
Fieldbus signal.
By using the optional Rosemount 333 HART Tri-loop, the HART signal can
convert up to three additional 4-20 mA analog signals.
With the HART protocol multidrop configuration is possible. In this case,
communication is restricted to digital, since current is fixed to the 4 mA
minimum value.
The transmitter can be connected to a Rosemount 751 Field Signal Indi ca tor,
or it can be equipped with an integral display.
The transmitter can easily be configured using a Rosemount 375 Field
Communicator or a PC with the Rosemount Radar Master software.
Rosemount 5300 Series transmitters can also be configured with the AMS

measurement accuracy may be reduced. The Upper Transition Zone is the

in the Lower Transition Zone. The Transition Zones vary depending on
probe type and product.

PROCESS
CHARACTERISTICS
The Rosemount 5300 Series has high sensitivity because of its advanced
signal processing and high signal to noise ratio. This makes it able to handle
various disturbances, however, the following circumstances should be
considered before mounting the transmitter.
Coating Heavy coating of the probe should be avoided since it may decrease the
sensitivity of the transmitter and lead 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

connection is significantly lower than process temperature with risk of coating in the upper part of
probe that may reduce the measurement signal. Consider using HP or STD probes in such
applications.
(1)(2)
Signal Quality Metrics (SQM) diagnostic option can give an indication of how
good the surface signal is compared to the noise, and when to clean the
probe.
BridgingHeavy product coating results in bridging between the two probes in a twin
lead version, or between the pipe and inner rod for coaxial probes, and may
cause erroneous level readings, so it must be prevented. A single lead probe
is recommended in these situations.
FoamThe Rosemount 5300 Series Radar T ransmitter measurement in foamy
applications depends on the foam properties; light and airy or dense and
heavy, high or low dielectrics, etc. If the foam is conductive and creamy, the
transmitter may measure the surface of the foam. If the foam is less
conductive the microwaves may penetrate the foam and measure the liquid
surface.
VaporIn some applications, such as high pressure boiling water, there is a heavy
vapor above the product surface that could influence the level measurement.
The Rosemount 5300 Series Radar Transmitter can be configured to
compensate for the influence of vapor.
Boiling HydrocarbonsFor products with very low dielectric constants, such as boiling hydrocarbons
and solids, the threshold may need to be lowered, and/or the Probe End
Projection (PEP) function activated.

Rosemount 5300 Series
For measuring interface level, the transmitter uses the residual wave of the
first reflection. Part of the wave, 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.
To measure interface, the following criteria have to be fulfilled:
•The dielectric constant of the upper prod uct must be known and sho uld
be constant. The Rosemount Radar Master software has a built- in
dielectric constant calculator to assist in determining the dielectric
constant of the upper product. (see “Dielectric Constant/Dielectr ic
Range” on page 5-23)
•The upper product must have a lower dielectr ic constant than the lower
product to have a distinct reflection
•The difference between the dielectric constants for the two products
must be greater than 6
•The maximum dielectric constant for the upper product: 10 for the
coaxial probe, 7 for the twin lead, and 8 for the single lead probes
•The upper product thickness must be greater than 5.1 in. (0.13 m) for
all probes, except the HTHP coaxial probe, which requires 8 in. (0.2 m),
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 with a low (<3) dielectric constant for the upper product and
a high (>20) dielectric constant for the lower product.
For such applications, the maximum measuring range is limited by the length
of the coaxial, rigid twin, and rigid single lead probes.
For flexible probes, the maximum measuring range is reduced by the
maximum upper product thickness, according to the diagram below . However,
characteristics may vary between the different applicat ion s .

Sometimes an emulsion layer (mix of the products) forms between the two
products and can affect interface measurements. For assistance with
emulsion applications, consult your local Emerson Process Management

V E SSEL
CHARACTERISTICS
Heating Coils, AgitatorsBecause the radar signal is transmitted along a probe, the Rosemount 5300
Radar transmitter is generally not affected by objects in the tan k. Avoid
physical contact with metallic objects when Twin Lead or Single Lead probes
are used.
Avoid physical contact between probes and agitators, as well as applications
with strong fluid movement, unless the probe is anchored. If the probe is able
to move 1 ft. (30 cm) from any object, such as an agitator, during operation,
the probe tie-down is recommended.
To stabilize the probe for side forces, a weight may be hung at the probe end
(flexible probes only) or fix/guide the probe to the tank bottom.
Tank ShapeThe guided wave radar transmitter is insensitive to tank shape. Since the
radar signal travels along a probe, the shape of the tank bottom has virtually
no effect on the measurement performance. Th e transmitter can handle flat or
dish-bottom tanks.
