Rosemount 3408 Exchangeable Electronics

Learn how the Rosemount 3408 Level Transmitter with exchangeable electrics makes maintenance and upgrade easy, saving time and reducing inventory cost

How It Works

The Rosemount 3408 uses 80GHz Fast Sweep Frequency Modulated Continuous Wave (FMCW) technology and smart algorithms to maximize measurement accuracy and reliability, even in small tanks and challenging fast-filling vessels. FMCW technology 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 the microwave frequency modulated over a span. The level is proportional to the frequency difference between the transmitted signal and received echoes.

Smart features help simplify each step in the product lifecycle.

Commission and configure remotely with Bluetooth® wireless technology. Powerful diagnostics provide early alerts when it is time to schedule maintenance and the on-board memory provides insight into the past 3 days of measurements. Echo curve profiles and alerts facilitate intuitive troubleshooting.

The Smart Echo Level Test enables proof-testing from the control room without changing the actual level and Smart Meter Verification provides a documented health check without interrupting the process.

With only two exchangeable electronic parts, complexity and inventory is reduced. The pre-calibrated cassette is suitable for all hazardous location approvals.

Operators troubleshooting and performing Rosemout 3408 remote proof-test from the control room

Keep people, plant assets, and the environment safe with safety certified instrumentation and remote proof-testing.

The Rosemount 3408 Level Transmitter is safety-certified to SIL2 according to IEC61508 for use in critical applications. It can be proof-tested remotely from the control room whilst left in-situ, keeping personnel safe. The Smart Echo Level Test lets you test in a real tank environment without changing the actual level, for a more convenient and safe test procedure.

Bluetooth® wireless technology lets operators communicate with the device remotely, keeping people off tank roofs
