Press Release Summary:
Rosemount® 5400 Series employs Radar Echonomics(TM) technology to detect weak radar echoes, handle weak and strong radar echoes simultaneously, and ignore false echoes. Low frequency Model 5401 (~6 GHz) is used in applications with turbulence, heavy vapors, or foam, or where there is a risk for deposits on antenna. High frequency Model 5402 (~26 GHz) utilizes narrower radar beam for installations that have tall or narrow nozzles or where the nozzle is close to tank wall.

Emerson Introduces Rosemount® Transmitter with "Radar Echonomics(TM)" Technology For Unique Level Measurement Reliability and User Cost Savings
First radar transmitter to deliver peak performance in all areas vital to radar level measurement
CHANHASSEN, MINNESOTA (June 2, 2005) - The Rosemount® 5400 introduced by Emerson Process Management is the first radar transmitter to offer peak performance in all three areas vital to radar level measurement: Echosensitivity - the ability to detect weak radar echoes reliably; Echodynamics - the ability to handle weak and strong radar echoes simultaneously; and Echologics - the ability to ignore false echoes. Naming the technology "Radar Echonomics(TM)," the company guided its innovative development to maximize operational benefits and user cost savings.
"The Rosemount 5400 series is another milestone for user benefit delivery from Rosemount instrumentation," says Carl Fjelkner, project manager for the 5400 development at Emerson Process Management. "Technology drives the benefits, as the 2-wire radar transmitter features an extremely high surface tracking capability, beyond that of other transmitters available today."
The Radar Echonomics technology of the Rosemount 5400 is focused on the following qualities:
1. Echosensitivity
High Echosensitivity means increased measurement reliability even under changing process conditions such as turbulence, vapors, foam and condensation. Echosensitivity is achieved by combining a number of new technologies. One example is the transmitter's Condensation Resistant Antenna. It is based on a larger active seal surface towards the tank making the transmitter more tolerant to dirt and condensation.
2. Echologics
New signal processing features in the transmitter separate surface echoes from false echoes to increase measurement reliability and reduce commissioning time and cost. By using "Measure and Learn" technology, suggestions for threshold and disturbance echo settings are automatically generated. The setup software also includes a spectra plot with "movie mode."
3. Echodynamics
In most process tanks, strong and weak radar echoes coexist. The echo from a turbulent fluid surface being agitated may be significantly weaker than the echo from the agitator. In order to take accurate readings, the radar sensor must be able to continuously track the weaker surface echo. This capacity, Echodynamics, means more reliable measurements and less process downtime during difficult measuring conditions.
Traditional 2-wire radar gives the benefits of having no moving parts and no contact with the liquid being measured. The measurement is unaffected by temperature, pressure and product density. For a process plant, the additional Radar Echonomics qualities of the Rosemount 5400 enable higher productivity, reduced cost of ownership, and increased process availability. Engineering and installation expenditures, and operating and maintenance expenditures are reduced.
The Rosemount 5400 Series is available in two models to increase application range: the Rosemount 5401, Low Frequency Transmitter (~ 6 GHz), is used in applications with turbulence, heavy vapors, foam or where there is a risk for deposits on the antenna. The Rosemount 5402, High Frequency Transmitter (~ 26 GHz) utilizes a narrower radar beam for installations that have tall or narrow nozzles, where the nozzle is close to the tank wall, or to avoid disturbing objects in the tank.
The Rosemount 5400 series is part of Emerson's broad range of intelligent, digital field devices that power the PlantWeb® digital plant architecture to improve plant efficiency by 2% and more through delivering asset optimization, process automation, and management execution. Further cost savings, increased plant availability, and enhanced safety and environmental compliance are achieved when the level transmitters are integrated into the PlantWeb architecture.
