Rosemount 5408 Level Transmitter

About Rosemount™ 5408 Level Transmitter

Rosemount 5408 is the new generation of non-contacting radars using FMCW technology for the highest precision level measurement.

Rosemount 5408 Level Transmitter

Dependable level, straight forward and easy

You need to adapt in a world of constant change. As experienced personnel retire and processes are pushed to run at tighter margins, you need your level measurement devices to be reliable, safe and easy to use.

Forty years of continuous development in the field of microwaves and FMCW technology has resulted in a new generation of non-contacting radars.

With the new Rosemount 5408 Level Transmitter simplification is key, from the pictorial instructions and graphical, intuitive wizards to the unique PTFE seal that does not contain any wetted o-rings.

How It Works

Measurement Technology

The 2-wire non-contacting radar Rosemount 5408 is optimized for best sensitivity in process applications. It uses fast-sweep Frequency Modulated Continuous Wave (FMCW) technology that deploys a continuous echo to maximize radar signal strength and produce a more robust and reliable measurement.

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

Ease of Use

Designed to simplify operator tasks by delivering ease-of-use at every touch point. The device offers an o-ring free PTFE seal solution and there is no minimal dielectric constant.

The Smart Diagnostics Suite provides early alerts for antenna build-up, weak power supply, or abnormal surface conditions. The local memory enables full insight to the last 7 days of measurements, alerts, and echo profiles. The echo curve tool functionality offers intuitive advanced troubleshooting capabilities.

Dedicated to Safety

Be safe at all times and know that you are compliant!

The Rosemount 5408:SIS is the ideal choice for functional safety such as overfill prevention. It is safety certified SIL 2 applications according to the IEC 61508. The Rosemount 5408:SIS also supports long proof-test intervals guarantied to suit your schedule, and it can be tested remotely without any process interruption.

The product has a yellow waist for easy visual recognition.

Solids Measurement

Rosemount 5408 also meets the demands of bulk solids level measurement. FMCW technology produces a continuous echo to maximize radar signal strength and produce a more robust and reliable measurement.

The advanced surface tracking ensures that the level reading is correct. There are three antenna options; cone, parabolic or process seal which enables Rosemount 5408 to operate reliably in very demanding applications.

The air purging system ensures that dust blockage of the antenna is avoided.

Hygienic Measurement

Hygienic requirements? No problem with the Rosemount 5408!

With 3-A Sanitary approval, Rosemount 5408 is now approved to be used in applications where a hygienic design is required. Tri-Clamp process connection and process seal antenna ensures that the Rosemount 5408 is the ideal solution for hygienic applications.
