Rosemount 5300 Series
Level-2
Taking Guided Wave Radar Benefits to the Next Level
MEASUREMENT PRINCIPLE
Rosemount 5300 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 a media with a
different dielectric constant, part of the energy is
reflected to the transmitter. The time difference
between the transmitted 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.
TECHNOLOGY BENEFITS
• No moving parts and no calibration means
minimized maintenance.
• Top-down, direct measurement, unaffected by
changing process conditions (such as density,
conductivity, temperature and pressure).
• Virtually unaffected by dust, vapor and
turbulence.
• Even suitable for small tanks, difficult tank
geometry, and interfering obstacles.
• Easy upgrade (existing and small openings
can be used).
SPECIAL 5300 FEATURES
Direct Switch Technology (DST)
The Rosemount 5300 delivers cutting edge
performance with DST, which is a rapid switch for
signal transmission between the transmitter and the
receiver. It minimizes signal losses, which results in a
two to five times stronger received signal compared
to other guided wave radar transmitters. It results in a
better signal-to-noise ratio and an increased ability to
handle disturbing factors.
It also enables long measuring ranges (up to 164 ft
(50 m)) and measurements on low reflective media
(dielectrics from 1.4), even with a single lead probe.
Probe End Projection (PEP)
PEP is a function to handle long measuring ranges
on media with low dielectrics. If the signal is not
reflected at the surface, the 5300 uses the probe end
as a reference to calculate the actual level.
Smart Galvanic Interface
Innovative ground plane configuration between
electronics, microwave and housing, results in a
more stable microwave performance and minimizes
unwanted disturbances. This improves the EMC
performance and provides a more robust
measurement.
Advanced Timing
The 5300 uses a patented timing method that gives
± 3 mm reference accuracy.
Robust Modular Design
The 5300 has a dual compartment head to separate
electronics from cable connection. It has
easy-to-access and robust cable terminals and an
optional easy-to-read display. The head can be
rotated 360º, and is removable while the tank is in
service. There is no matching between head and
probes. All of this adds up to reduced cost and
increased safety. See “Transmitter Housing” on
page 6.
Full Range of Probe Styles for Application
Flexibility
Probes are available in different styles and materials,
also with options to handle extreme pressure and
temperature. See “Probes” on page 8.
Powerful Configuration Tools
Rosemount Radar Master™ with its user-friendly
interface is the ultimate setup and troubleshooting
software. See “Configuration” on page 5.
Advanced PlantWeb™ functionality
The 5300 powers the PlantWeb architecture by
delivering the best Multivariable™ transmitter (both
level and interface from the same 2-wire unit), the
best installation practices, and the best field
intelligence with advanced diagnostics for HART
®
and F
OUNDATION™ fieldbus. This enables proactive
maintenance for increased process availiability. See
“Configuration” on page 5.
