Bürkert improves functionality of its Element controllers
13 February 2016
The functionality of Bürkert's Element Type 869x range of positioners and process controllers has has recently been improved to include ATEX and IECEx approvals.
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.
The latest improvements include ATEX and IECEx approvals for operation in Zones 2/22 and 1/21 potentially explosive atmospheres, 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 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.
