Rosemount Level Transmitter 3300

Detailed Product Description

Easy installation and commissioning through
two-wire technology, and pre-configured
transmitter or user-friendly configuration with
included PC software package.
Trouble-free operation since the transmitter is
virtually unaffected by dust,vapor, interfering
obstacles, and turbulence. It is even suitable
for small or oddly shaped tanks.
Direct level measurement means no
compensation for changes in temperature,
pressure, density, dielectric, or conductivity.
Robust modular design with dual
compartment housing, which can be removed
without opening the tank.
High application flexibility with a wide range of
probe styles in different materials and options
to handle corrosive media, extreme
temperature and pressure.
Multivariable level and interface transmitter
reduces process penetrations and installation
costs.
Measurement Principle
Rosemount 3300 Series is based on the Time
Domain Reflectometry (TDR) technology.
Low power nano-second microwave pulses are
guided down a probe submerged in the process
media.
When a radar pulse reaches media with a different
dielectric constant, part of the energy is reflected
back to the transmitter. The time difference between
the transmitted (reference) and the reflected pulse is
converted into a distance from which the total level or
interface level is calculated.
The intensity of the reflection depends on the
dielectric constant of the product. The higher the
dielectric constant value is, the stronger the reflection
will be.
The transmitter uses Dynamic Gain Optimization
which means it automatically adjusts gain to
maximize the signal-to-noise ratio in each
application. This increases measurement reliability
and capability.
Applications
The Rosemount 3300 Series can be used for level
measurements on most liquids, semi-liquids, some
solids and liquid/liquid interfaces.
The 3300 Series consists of two models:
Rosemount 3301, Guided Wave Radar Level
Transmitter for liquids and some solids.
Rosemount 3302, Multivariable Guided
Wave Radar Level and Interface Transmitter
for liquids.
Rosemount 3300 Guided Wave Radar transmitters
offer high reliability and performance.
Measurements are virtually unaffected by
temperature, pressure, vapor gas mixtures, density,
turbulence, bubbling/boiling, varying dielectric media,
and viscosity.
Since the waves are guided along the probe, this
technology is excellent for small and narrow tanks /
tank openings.
The Rosemount 3300 Series is suitable for
measurements in the following industries:
Oil, gas and refining
Chemical and petrochemical
Power
Pulp and paper
Water and sewage treatment
Food and beverage
Pharmaceutical;
System Integration
INPUTS / OUTPUTS
The 3300 Series transmitter uses the same two wires
for both power supply and output signal
(loop-powered).
See page Level-16 for more information about power
supply.
Measurement data is transmitted as an analog
4-20 mA signal with a superimposed digital HART®
signal. The HART® signal can be used in a multidrop
mode.
As an option, the 3300 Series is available with
Modbus output (requires separate power supply).
However, HART® communication is used for
configuration.
By sending the digital HART® signal to the optional
HART® Tri-loop, it is possible to have up to three
additional 4-20 mA analog signals.
See the Rosemount 333 HART® Tri-loop Product
Data Sheet (document number 00813-0100-4754)
for additional information.
The transmitter is available with Intrinsically Safe or
Explosion Proof certification. A safety isolator such
as a zener barrier must be used for intrinsic safety.
Refer to Product Certifications on page 17 and
Ordering Information on page 28.
DISPLAY
Data can be read locally from the optional integral
display or remotely by using the 4-digit Rosemount
751 Field Signal Indicator (see the Rosemount 751
Product Data Sheet, document number
00813-0100-4378).
MEASUREMENT PARAMETERS
From one Rosemount 3300 Series radar transmitter
it is possible to receive multiple process variables.
Details on parameters are given in the table below.
* Interface measurement only for fully submerged probe, see
page Level-11.
CONFIGURATION
Configuration can be performed using either a 375
Field Communicator or a PC with the Radar
Configuration Tools software. This user-friendly
software is Windows based and it is included in the
transmitter delivery.
To communicate with the transmitter, a HART®
modem is required (see picture on page Level-4).
The HART® modem is available in an RS232 or USB
version (see Accessories Model 3301/3302 on
page 36).
Rosemount 3300 Series transmitters are compatible
with the AMS Suite plant management software,
which can also be used for configuration.

emersonprocess.com/AMS.
By filling out the Configuration Data Sheet (CDS), it is
possible to order a pre-configured transmitter.
POWER SUPPLY
4-20 mA with HART®
The input voltage (UI)for HART® is 11-42 V dc
(11-30 V dc in IS applications, and 16-42 V dc in
Explosionproof / Flameproof applications).
The maximum load resistance and power supply
limitations for typical operating conditions can be
obtained from the following diagrams and table.

SAFETY NOTE
A safety isolator such as a zener barrier is always needed for
intrinsic safety.
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.
