Burkert's new Element concept provides a complete systems approach, linking clean-line valves, sensors, positioners and valve actuators in a simple architecture to solve total control loop processes. With 'unlimited' modularity, the Element system saves processing time by offering total control products for media from slurries to steam, and from de-ionised water to hydrochloric acid.
Element provides a modular programme of process control devices that combine to deliver products for specific process requirements, whether they be in environmentally aggressive or hygienic areas. The devices include valves for on/off as well as modulating control, sensors for ph/ORP, conductivity and level, digital positioners, control heads and actuators, all of which are designed for valve mounting, delivering excellent space saving and performance. In addition, the integration of backlit displays and coloured status lights on many Element products enables users to have more interaction and transparency in their systems, by being able to quickly determine diagnostic messages at a glance.
Reduced engineering and maintenance
Autonomous and flexible, Element makes possible control products that would otherwise require control cubicles; and it does so with less investment in planning, assembly and maintenance, as well as wiring and pneumatic hose connections. Key to these advantages is the physical nature of the Element control platform and the system's connectivity, both local and distributed.
Rugged and clean, the Element platform features clean-line control products that combine the chemical characteristics of engineered polymers with the endurance and finish of stainless steel. As a result, Element devices are easy to clean: no flaking paint, no interstices collecting dirt, no protruding pneumatic lines. Moreover, the fact that the Element units offer simple maintenance in a throwaway society means that they are more environmentally friendly than other current products.
As regards connectivity, local distributed intelligence and full connection to the superior co-ordinating level are provided at the same time in an optimal device design for a wide range of applications. Burkert's ongoing development in combining control and communications technology with process hardware is excellent, with factory floor communications and status monitoring available via simple 4-20mA or via a range of digital protocols.
In addition, Element valves and sensors can also be linked via Burkert's AirLINE 8644 system. This overcomes plant standardisation and communication protocol issues, by integrating Burkert high-performance solenoid valves with analogue and digital I/O modules and fieldbus communications from PLC vendors including Siemens, Rockwell, GE Fanuc, Bosch, Beckhoff, Phoenix Contact, WAGO and Hitachi.
