Emerson Process Management is announcing the addition of safety certification per IEC 61508 to the innovative Rosemount 3051S Series pressure transmitter range.

Emerson Process Management is announcing the addition of safety certification per IEC 61508 to the innovative Rosemount 3051S Series pressure transmitter range.

For the first time, a field-proven, highly reliable device for basic process control can be easily converted to a TUViT certified pressure transmitter for use in a SIL 2 or SIL 3 safety instrumented system.

Made possible by the scaleable architecture of the Rosemount 3051S, supervisory electronics are simply added to the transmitter either at time of order or after purchase in the field as a "plug and play" upgrade.

The 3051S transmitters are components of Emerson's new PlantWeb Smart SIS safety management architecture where they are integrated with safety-certified final control elements and safety systems in a unique, digital intelligent safety loop approach that enables users to implement safer plants.

The 3051S transmitter for safety systems uses the same basic design and innovations as those used in PlantWeb digital plant architecture for mainstream Basic Process Control System automation.

Utilising certified devices for safety applications eases user compliance to the new IEC 61511/ANSI ISA 84.00.01 (2004) safety standards for the process industry sector and minimises the costly documentation and analysis efforts associated with the alternative prior-use methodology.

Customer costs are further reduced by eliminating duplicate training, maintenance, and inventory costs because the same pressure instrument can be used in both basic process control and safety instrumented systems.

With safety certification built on the foundation of the field proven 3051S, users now benefit from industry leading reliability and performance in their critical safety shutdown applications.

The flexible 3051S SuperModuleTM design platform also offers a complete family of primary elements, diaphragm seal assemblies and instrument manifolds which enable highly integrated and compact measurement solutions to serve all the flow, level, and pressure applications in a process plant.

"From the initial conception of the 3051S Series, the goal was to provide users with the most flexible, reliable, and cost-effective family of process measurement solutions", commented Steve Sonnenberg, president of Emerson's Rosemount division.

"Safety certification is a natural extension to the scaleable 3051S offering just like Foundation fieldbus, advanced diagnostics and control functionality have been "plug and play" options of the SuperModule design platform.

"The innovative 3051S, which has received over 35 patents, provides users with one common platform that can be scaled up to meet any application requirement resulting in significantly reduced capital, maintenance, inventory and regulatory costs".

To improve plant safety, the Rosemount 3051S goes far beyond being certified to the new IEC 61508 safety standard.

Required proof test intervals can be extended to five years, eliminating unnecessary process interruptions and risk to personnel.

The robust, hermetically sealed 316L stainless steel SuperModule housing is designed to withstand the harshest field environments.

The 3051S Integrated Solutions allow the transmitter to be direct mounted close to the process, providing safer and more reliable measurements, reducing potential leak points by 90%.

Unparalleled performance and advanced diagnostics ensure the most accurate and timely process information is available to make critical decisions.

The Rosemount 3051S pressure transmitter is one component of the PlantWeb Smart SIS safety management solution that includes safety loops made by integrating Emerson's sensors, safety systems, final control elements and software.

Engineered with the help of Emerson safety professionals, the safety solutions enable safer facilities, streamlined compliance, and life-cycle cost savings from engineering, through operations and maintenance.

The Rosemount 3051S Pressure Transmitter is also 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 optimisation, process automation, and management execution.

Further cost savings, increased plant availability, and enhanced safety and environmental compliance are achieved when the transmitters are integrated into the PlantWeb architecture.
