This firm has enhanced its metsoDNA Turbine Control by integrating in fast turbine control and other features to improve its cost efficiency and ease of maintenance. The fast, redundant control handles control cycles down to 5 ms for any size turbine. A new servo valve control I/O can control any milliamp range of servo valves. Vibration monitoring and protection features are integrated into the I/O card and process controllers, and new I/O cards can read standard accelerometers and eddy current sensors. Measurements can be used for protection and normal online monitoring, as well as more developed diagnostic purposes. The integration eliminates many extra transmitters and amplifiers traditionally required. — Metso Corp., Helsinki, Finland
