Rosemount™ 5408 Level Transmitter - Non-Contacting Radar

The New Rosemount™ 5408 Non-Contacting Radar Level Transmitter uses enhanced technology and Human Centered Design to deliver accurate, reliable measurements.

Using two-wire FMCW technology the Rosemount 5408 deploys a continuous echo to maximize radar signal strength and produce a more robust and reliable measurement. Delivering ease-of-use at every touch point, the Rosemount 5408 uses an intuitive software interface to guide the operator through installation, commissioning, proof-testing and maintenance.

Safety certified to IEC 61508 for SIL 2 applications, the Rosemount 5408:SIS reduces cost of risk, increases efficiency and protects people and the environment.

 

 

Rosemount™ 5408 Level Transmitter - Non-Contacting Radar. 

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

+ Measurement principle

The Rosemount 5408 and 5408:SIS are two-wire non-contacting radar transmitters for continuous level measurement of liquids and slurries. 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.

+ Technology to redefine reliability

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.

+ 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.

1. Refer to the IEC 60770-1 standard for a definition of radar specifi performance parameters and if applicable corresponding test procedure.
2. Ambient temperature effect specification valid over temperature range -40 °F to 176 °F (-40 °C to 80 °C).
3. 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.
4. The Rosemount 5408:SIS has two operational modes: Safety (SIS) and Control/Monitoring. Safety  (SIS) mode must be set when used in Safety Instrumented Systems. Control/Monitoring mode is intended for use in a Basic Process Control System (BPCS).
