Introduction

Measurement principle

The Rosemount™ 5408 and 5408:SIS are two-wire transmitters for continuous level measurements over a broad range of liquids,
slurries, and solids. The measurement principle is fast-sweep Frequency Modulated Continuous Wave (FMCW).

Radar signals are continuously transmitted towards the product surface with a microwave frequency modulated over a span. The
level is proportional to the frequency difference between currently received and transmitted signal.

D. Reflected signal

Technology to redefine reliability

The Rosemount 5408 and 5408:SIS are optimized for reliable and accurate performance even in challenging process conditions.
FMCW technology maximizes radar signal strength and produces a robust and reliable measurement (with 30 times more power on
the surface than traditional two-wire non-contacting radars).

The transmitters can operate with only 12 Vdc lift-off voltage and they are self-powered for up to 2 seconds to maintain operation
despite cable glitches or lightning.

Rosemount 5408 Series

Ease-of-use at every touch point

The Rosemount 5408 and 5408:SIS are designed to simplify operator tasks. They deliver ease-of-use at every touch point, from the
pictorial user instructions and graphical, intuitive wizards to the PTFE seal that requires no O-ring material for simplifying model
selection.

Dedicated to safety

The Smart Diagnostics Suite provides operators with early alerts in case of antenna build-up, weak power supply, or abnormal
surface conditions. Also, a local memory enables full insight into the last seven days of measurements, alerts, and echo profiles.

The Rosemount 5408:SIS is the ideal choice for functional safety such as overfill prevention. It is safety certified (SIL 2/SIL 3),
supports long proof-test intervals guaranteed to suit your schedule, and can be tested remotely without any process interruption.

Application examples

The Rosemount 5408 and 5408:SIS are ideal for level measurements over a broad range of liquid and solids applications. The
transmitters are virtually unaffected by changing density, temperature, pressure, media dielectric, pH, and viscosity. Non­contacting radar level is ideal for harsh conditions such as corrosive and sticky media, or when internal tank obstructions are a
limiting factor.

Storage and buffer tanks

The Rosemount 5408 provides accurate and reliable level measurement for both metallic or non-metallic vessels containing almost
any liquid (e.g. oil, gas condensate, water, chemicals).

Reactors

The Rosemount 5408 is ideal for the most challenging applications, including reactors where there can be agitation, foaming,
condensation as well as high temperatures and pressures.

Blenders and mixers

The Rosemount 5408 can help you withstand the rigors of blenders and mixing tanks. Easy to install and commission, it is also
unaffected by virtually any fluid property change.

Open atmospheric applications

The Rosemount 5408 measures reliably in open applications, from short range sumps or ponds to long range dams.

Still pipe and chamber installations

The Rosemount 5408 is an excellent choice for level measurement in tanks with still pipes. It may also be used in chambers, but
guided wave radar is generally the best fit for these applications. See Still pipe/chamber installations for installation guidelines.

Bulk solids

The Rosemount 5408 is the ideal solution for small to medium sized silos with rapid level changes. The narrow beam avoids internal
obstructions while still keeping good level measurement.

Safety applications

The Rosemount 5408:SIS is the ideal choice for safety functions such as overfill prevention, level deviation monitoring or dry-run
prevention.

Performance specifications

General

Conformance to specification (±3σ [Sigma])

Technology leadership, advanced manufacturing techniques, and statistical process control ensure specification conformance to at
least ±3σ.

Reference conditions

■ Measurement target: Metal plate, no disturbing objects

■ Temperature: 68 to 86 °F (20 to 30 °C)

■ Ambient pressure: 14 to 15 psi (960 to1060 mbar)

■ Relative humidity: 25-75%

■ Damping: Default value, 2 s

Instrument accuracy (under reference conditions)

±0.08 in. (2 mm)

(1) Refers to inaccuracy according to IEC 60770-1 when excluding installation dependent offset. See the IEC 60770-1 standard for a definition of radar

specific performance parameters and if applicable corresponding test procedures.

Rosemount 5408 Series

Rosemount 5408:

Rosemount 5408:SIS:

130 ft. (40 m)

82 ft. (25 m) in Safety (SIS) mode

Note that a combination of adverse process conditions, such as heavy turbulence, foam, and condensation, together with products
with poor reflection may affect the measuring range.

Accuracy over measuring range

The measuring range is limited by the blind zone at the very top of the tank. In the blind zone, the accuracy exceeds ±0.20 in. (±5
mm) and measurements may not be possible. Measurements close to the blind zone will have reduced accuracy (see Figure 2).

For the extended cone antennas, the reduced accuracy zone ends 11.8 in. (30 cm) below the antenna end.

(2) Ambient temperature effect specification valid over temperature range -40 °F to 176 °F (-40 °C to 80 °C).
(3) The Rosemount 5408:SIS has two operational modes: Safety (SIS) and Control/Monitoring. Safety (SIS) mode must be set when used in Safety Instru-

mented Systems. Control/Monitoring mode is intended for use in a Basic Process Control System (BPCS).

The figures given in Table 8 should be considered as guidelines; the total measuring range may differ depending on other
contributing application conditions such as product filling, how the product piles up, silo diameter vs. angle of repose, internal
obstacles within the silo, etc.

Beam width and beam angle

The transmitter should be mounted with as few internal structures as possible within the signal beam. Refer to Table 9 for beam
angle and Table 10 for beam width at different distances.
