Emerson launches two new Rosemount radar transmitters

Posted: 5 May 2003

Emerson Process Management has introduced new multivariable, digital radar technology transmitters that deliver next generation radar level measurement for liquid level and interface.

The Rosemount 3300 Guided Wave Radar Transmitter, the first ever 2-wire level and interface radar transmitter, and the Rosemount 5600 non-contact Radar Level Transmitter.

Rosemount 3300 — the first 2-wire level and interface transmitter
Quite simply the most sophisticated, loop powered radar transmitter today, the Multivariable Rosemount 3300 allows simultaneous interface and level measurement in process tanks.

Using guided wave radar technology, a microwave radar pulse travels down a probe inside the tank, and receives reflected signals from liquids levels or materials surrounding the probe.

Both rigid and flexible probes are available and they can be cut to length on site. There are probe versions for use in long nozzles, with small fittings/flanges, or in narrow bridles on separators. The modular construction allows the head electronics to be detached, freely rotated, or replaced without opening the tank. Above all, the single small diameter penetration for level and interface measurement makes a simple and inexpensive installation.

Advanced signal processing gives higher resolution and more reliable measurements in applications where other transmitters fail. With turbulent liquid surfaces, or steam laden vapor spaces-these are the applications where the 3300 thrives. Guided wave radar can also cope with probe coating and material build-up better than other contacting level technologies, using Dynamic Gain Optimization available within the digital signal processing.

Rosemount 3300 can be retrofitted onto existing loop cabling. Being an intelligent MultiVariable transmitter, further benefits arise within PlantWeb digital plant architecture, using HART fieldbus communications, when both surface level and liquid/liquid interface level can be monitored simultaneously.

Being AMS Aware, the Rosemount 3300 is compatible with the requirements of modern digital plant control systems. The Rosemount 3300 is available as intrinsically safe or explosion-proof, built to the industrial standards and capable of the performance you expect from a Rosemount product.

The Rosemount 5600 Series is a powerful, non-contact radar level measurement transmitter for process applications, on liquids and slurries. The unit is available with a full range of antennas to suit any application.

Smart FMCW echo-tracking features and advanced signal processing techniques combine to give the 5600 high reliability and accuracy, even in the toughest conditions. The Rosemount 5600 uses a software module that incorporates all the experience accumulated in thousands of radar installations around the world to discriminate between false echo sources and true surface echoes. This software can also use information provided by the operator about stirrers or other obstructions as a complement to the automatically collected data.

The Rosemount 5600 integrates with PlantWeb digital plant architecture and can provide HART or FOUNDATION fieldbus digital communications protocols, or a standard analog output. For local monitoring, the unit has an integral display and keypads for basic initial configuration. Remote displays and as many as six externally mounted temperature sensors can be driven from the Rosemount 5600 transmitter.

The Rosemount 5600 brings the best in radar level gauging technology — accuracy, reliability, no liquid contact, no moving parts — with full industrial control interfacing.
