Rosemount 5400 Series -Superior 2-wire Radar Level Transmitters
You cannot afford a single misstep in your process. That’s why we used our 30 years of proven radar expertise to design the new non-contacting Rosemount 5400 Series to focus your plant’s profitability. It delivers higher reliability, improved safety and requires less maintenance and configuration. As a result you will have reduced downtime and lower installation and operating costs.
Maximum mounting and application flexibility is ensured with a wide range of antennas and two models with different microwave frequencies, 5401 (6 GHz) and 5402 (26 GHz)
Dual Port Technology enables a stronger signal than other 2-wire radar transmitters, providing better measurement reliability.
Condensation Resistant Antenna is much less susceptible to coating, increasing reliability and reducing maintenance
Faster and simpler commissioning with the easy to use Measure-and-Learn™functionality in the transmitter
Circular Polarization reduces echoes from obstacles and tank walls
Advanced transmitter software can be easily configured using the user-friendly software ”Rosemount Radar Master” (supplied free of charge)
Easy integration into new or existing plants with a choice of FOUNDATION ™ fieldbus with extensive support for PlantWeb® Alerts or 4-20 mA with superimposed HART®
Safety Instrumented Systems Suitable
These features and many more were developed with the customer’s bottom line in mind and make the Rosemount 5400 Series deliver like no 2-wire radar in history. In fact, it’s all that Emerson does best: innovation that delivers clear business results

Features & Benefits
Radar is a continuous level measurement technique that offers several advantages. It is virtually unaffected by temperature, pressure and vapor gas mixtures. It is a non-contacting method with no moving parts and therefore requires little or no maintenance. It measures the level directly and is therefore unaffected by most fluid property changes, including but not limited to density and viscosity changes.Additionally, the Rosemount 5400 Series offers the following benefits:

Applications
The Rosemount 5400 Series can be used for continuous non-contacting level and volume measurements of liquids and semi-liquids. The unchallenged Signal-to-Noise ratio in conjunction with a wide range of antennas and the flexibility of having a low- and high frequency version make it suitable for almost any application in the process industry.
| Buffer Tanks For measurements in tanks with a calm or slightly turbulent surface, the Rosemount 5400 Series transmitter is the preferred choice, particularly where the tank has a narrow nozzle opening. |  |
| Chambers and stilling wells The 5400 is an excellent choice for level gauging in tanks with stilling wells. It may also be used in some chambers, but Guided Wave Radar is generally the best fit for these applications. |  |
| Reactor Tanks The state-of-the art signal processing provided by the 5400 makes it a very suitable choice for tanks with harsh and varying process conditions. |  |
