ABB 2600 pressure transmitters pass the Emerson DeltaV test

31 August 2011

Operators of Emerson DeltaV Digital Automation System can now use the ABB 2600T series of pressure transmitters following its successful completion of the Emerson DeltaV Interoperability Test.

During the test, devices are connected to Emerson's DeltaV automation system to assess their performance under a full range of conditions likely to be experienced in real-life applications.

"DeltaV users now have more freedom in their choice of pressure transmitters," says Trevor Dunger, ABB Product Specialist, Pressure & Level, "and can make use of the wide range of capable, highly accurate 2600T series of ABB pressure transmitters."

The range of ABB 2600T pressure transmitters includes absolute, gauge and differential transmitters, allowing users to standardize transmitter installations across a whole plant.
A key part of the 2600T's simplicity lies in its use of ABB's new universal HMI. A menu-based clear text enables 2600T transmitters to be configured in just seconds, compared to the several minutes required for competitor devices using handheld configurators. This menu can also be used to quickly select and display different variables, providing operators with fast access to additional data.

Operators can also quickly repair or upgrade the transmitter in the field simply by changing the electronics module, rather than the whole transmitter. The transmitter performs an auto configure function so no additional configuration is required, avoiding the time and cost of removing a sensor from a pipeline or network.

Further time savings are made possible by the 2600T's optional Through-The-Glass (TTG) indicator. Operators can adjust settings without moving the cover, ideal for hazardous applications.

The 2600T range also includes a standard model for pressures up to 600 bar, which is fully compliant with the hardware and software requirements of IEC61508 for SIL2 and TUV Nord applications. It also comes with IEC hazardous area certifications IEC Ex ia, IEC Ex d and IEC Ex nL, plus all of the major international certification standards including GOST, FM and CSA.

Another key feature of the 2600T range is the inclusion of 20 standard critical and non-critical diagnostic functions. Where an alarm condition occurs, messages are displayed in clear text on the indicator and can be relayed to a control system via HART, Profibus or Foundation Fieldbus. The transmitter is also programmed with the necessary software to integrate with both ABB's 800xA and third-party control systems.

The 2600T series has the optional extra of ABB's Plugged Impulse Line Detection system (PILD). This compares the application background noise against a pre-programmed baseline to detect blocked impulse lines, with any blockages being relayed as an alarm via HART, Profibus or Foundation Fieldbus.

A major development is the availability of a vertically flanged mounting variant, offered as an alternative to the Co-planar flange design. With this feature, ABB 2600T transmitters can be fitted to existing co-planar manifolds from different suppliers, eliminating the work associated with repositioning pipes.

Other new features include preset linearisation functions for level measurement applications in cylindrical and spherical tanks, enabling tank levels to be accurately measured based on volume. Also included is a square root extractor function, enabling the 2600T to be used for differential pressure flow applications.

The high performance of the 2600T range is further supported by ABB's extensive choice of remote seal options. Available in a wide choice of materials and process connections, ABB's remote seals are proven to operate leak-free even under high vacuum. The range includes high performance-low thickness diaphragms of <0,06 mm, offering accurate measurement at lower pressures and reducing temperature errors in applications using longer capillary lengths.
