Emerson Introduces Next Generation of Rosemount Guided Wave Level Instrumentation

Proven guided wave radar reliability now available for improving uptime, reducing cost, and enhancing safety in more applications

CHANHASSEN, MINNESOTA (October 25, 2007). Emerson Process Management announces the release of the Rosemount® 5300 Series High Performance Guided Wave Radar. The Rosemount 5300 combines the proven technology of existing Rosemount radar products with new features that allow more users in oil & gas production, refining, petrochemical, chemical, power, and water & waste treatment to achieve improved uptime, reduced cost and enhanced safety. Applications include tanks, bridles, silos with solids, underground tanks and liquid gas.

The unique Direct Switch Technology (DST) function of the Rosemount 5300 provides an echo signal that is two to five times stronger than other GWR transmitters. The improved signal to noise ratio means enhanced ability to handle difficult measuring conditions like long measuring distances and lower dielectrics, also with a single lead probe. By managing more applications reliably, unplanned downtime can be avoided.

The Rosemount 5300 features the modular design, state-of-the-art electronics and robust housing leveraged from the Rosemount 5400 non-contacting radar. Electronics and cable connections are located in separate compartments, providing safer handling and improved moisture protection.

The Rosemount 5300 also has a longer measuring range and measures in lower dielectrics media than other GWR products. In addition, it has improved performance in product interface applications and in sticky liquids causing probe deposits.

The probes of the Rosemount 5300, leveraged from the proven Rosemount 3300, provide multiple layers of protection enabling reliable operation in high temperature and high pressure applications up to 752º F (400º C) or 5000 psig (345 bar). The transmitter seal includes a temperature and pressure barrier in a flexible assembly to handle forces induced by probe movement and temperature variations. A second brazed hermetic, gas-tight seal provides another layer of protection, and the entire assembly is welded into a stainless steel sleeve for total robustness. Probes are available in materials such as SST, Hastelloy, Monel, and PTFE-covered SST to withstand corrosive environments.

The two-wire technology of the Rosemount 5300 enables fast and inexpensive installation. FOUNDATION(TM) fieldbus, HART and PlantWeb functionality means the transmitter integrates easily into new or existing control systems. Add maintenance-free operation and the result is a quicker return on the level instrumentation investment.

Rosemount 5300 High Performance Guided Wave Radar 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.
