Bürkert strengthens ELEMENT range of process controllers and positioners

Fluid controls expert Bürkert has strengthened its highly impressive ELEMENT range of process controllers and positioners. Among the raft of improvements are ATEX and IECEx approvals, an extended ambient temperature range, and greater diagnostic functionality.

The ELEMENT range of Bürkert positioners and process controllers has revolutionised the design and operation of many automated processes since its launch in 2008. This is especially the case in hygienic applications and those that benefit from a decentralised control structure.

ELEMENT range sets standard for fluid controls

With a process of continuous improvement, Bürkert has recently improved the functionality of the Type 869x positioners and controllers. Initially designed to operate Bürkert's CLASSIC process valves, the ELEMENT range has also become established as a control mechanism for 3rd party process valves, especially in the food and beverage industry.

Rapidly becoming a global benchmark for this type of intelligent process control valve, the ELEMENT range has set the standard for the major manufacturers.

Positioner and process controller improvements

The latest improvements include ATEX and IECEx approvals for operation in Zones 2/22 and 1/21 where potentially explosive atmospheres may exist as well as an extension to the ambient operating temperature range, down to -10°C.

There has also been a considerable increase in the number of diagnostic features as well as the integration of this device family to the Bürkert COMMUNICATOR tool which can configure and set the operational parameters for each controller and positioner.

The latest diagnostic functions allow the status to be displayed using standardised symbols, according to NAMUR recommendation (NE107) as well as the ability to output the diagnostic messages using binary signals. In addition, LED lights provide an instant and more visible indication of valve status.

Profibus, DeviceNet and AS-I compatibility

In terms of communication, the Type 869x range is compatible with AS-i, DeviceNet and Profibus, allowing the controllers to be integrated into a range of applications and process structures. Using this range of fieldbus protocols allows individual valves to be connected using just one or two cables to link back to a local controller or up a level to a factory wide bus network.
