Bürkert improves functionality of ELEMENT controllers

Initially designed to operate Brkert's CLASSIC process valves, the ELEMENT range has also become established as a control mechanism for third 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.

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 -10degC. There has also been a considerable increase in the number of diagnostic features as well as the integration of this device family to the Brkert COMMUNICATOR tool which can configure and set the operational parameters for each controller and positioner.

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 there are LED lights which provide an instant and more visible indication of valve status.

In terms of communication, the Type 869x range has compatibility 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.
