Product Description

Emerson Rosemount 5408 Non-Contact Radar Level Transmitter 

The Emerson Rosemount 5408 Non-Contact Radar Level Transmitter is a high-performance, guided-wave radar (GWR) solution designed to deliver accurate and reliable level measurement for liquids, slurries, and bulk solids in challenging industrial environments. Part of Emerson's advanced Rosemount 5400 series, the 5408 model leverages state-of-the-art frequency-modulated continuous-wave (FMCW) radar technology to provide precise, real-time data with minimal maintenance. Its non-contact design eliminates the risks associated with moving parts or material buildup, making it ideal for applications where hygiene, durability, and process efficiency are critical.

Core Technology and Operating Principle
The Rosemount 5408 operates on the time-of-flight (ToF) principle, emitting microwave pulses from an antenna that reflect off the surface of the measured medium and return to the transmitter. The device calculates the level by measuring the time delay between signal transmission and reception. Unlike traditional mechanical or capacitive level sensors, the 5408 uses non-contact radar, ensuring no exposure to process media and eliminating wear or contamination risks.

A key innovation is its 24 GHz FMCW radar technology, which offers superior resolution and signal stability compared to pulsed radar systems. This allows the transmitter to detect even minor level changes with high accuracy, even in tanks with agitators, foam, or vapor layers. The 5408's advanced signal processing algorithms filter out false echoes caused by tank obstructions, ladders, or vessel walls, ensuring consistent measurements in complex geometries.

Technical Performance and Features
The Rosemount 5408 delivers exceptional accuracy with a typical linearity of ±1 mm (±0.04 in) for liquids and ±5 mm (±0.2 in) for solids, regardless of environmental factors such as temperature, pressure, or dielectric properties of the medium. It supports measurement ranges up to 20 meters (66 feet) for liquids and 15 meters (49 feet) for solids, accommodating a wide variety of tank and silo configurations.

The transmitter is available in multiple configurations to suit diverse applications:

Antenna Options: Horn, rod, or parabolic antennas for optimal signal focus in different process conditions.

Advanced Diagnostic and Self-Monitoring Capabilities
The 5408 incorporates predictive diagnostics to enhance operational reliability and reduce unplanned downtime. Continuous health monitoring tracks parameters such as signal strength, echo quality, and sensor integrity, issuing alerts for issues like antenna coating buildup, process disturbances, or electronic failures. These diagnostics are accessible via local displays, remote interfaces, or Emerson's AMS Device Manager, enabling proactive maintenance planning.

A standout feature is the SIL 2/3 certification (per IEC 61508), qualifying the transmitter for safety-critical applications in industries like oil and gas, chemical processing, and pharmaceuticals. The device also supports partial-stroke testing (PST) for safety instrumented systems (SIS), ensuring compliance with functional safety standards without interrupting operations.

Ease of Use and Integration
Installation and commissioning are streamlined with the 5408's user-friendly interface, which includes a backlit LCD display and intuitive push-button controls for configuration. The transmitter supports infrared (IR) and Bluetooth® connectivity, allowing technicians to adjust settings remotely using a smartphone or tablet via Emerson's Mobile Remote View app. This eliminates the need for direct access to the device, particularly beneficial in hard-to-reach locations.

Integration with Emerson's PlantWeb® digital ecosystem enables real-time data analytics, asset optimization, and predictive maintenance. The 5408's multivariable capability allows it to measure level, interface, and temperature simultaneously when paired with external sensors, providing comprehensive process insights.

Applications Across Industries
The Rosemount 5408's versatility makes it a preferred choice for demanding applications:

Oil and Gas: Monitoring crude oil, refined fuels, and liquefied natural gas (LNG) in storage tanks and separators, even under high pressure or corrosive conditions.
Chemical Processing: Measuring aggressive chemicals, solvents, and acids in reactors and distillation columns, where material compatibility and accuracy are critical.
