Positioners and special control units for automated applications in technological processes

Operating conditions on-site considerably influence the operating condition and functionality of technological processing plant. In addition to the process-related eventual formation of deposits or contamination, accessibility and available space are important criteria when considering the meaning of maintenance-friendly. The solution to this problem is a new generation of control units. Instead of external attachments, you have an integrated air supply adapter as exactly fitting supplement to the pneumatic pivoting actuator actubar®, presenting a pneumatic interface on the upper side of the actuator. Plant construction and operation is much less liable to register malfunctions, simply because all types of external piping or hose conduit are just not needed any more. Furthermore, thanks to special air-supply adapters, these advantages can be put to use even for positioners from other known manufacturers. Based on the same system and equipped with the same advantages, additional decentralised controls with integrated pressure measurement were developed: a control for valves with inflatable seals and a control for actuators, which guarantee safe and energy-efficient operation between compressor and compressed air supply.
