Process control systems: Invensys Eurotherm nanodac. The nanodac recorder / controller offers the ultimate in graphical recording combined with PID control in a quarter DIN box. This is a Control Engineering 2011 Engineers' Choice (EC) nominee.
The nanodac recorder and controller offers the ultimate in graphical data recording combined with two PID control loops in a quarter DIN size. The compact panel mount unit offers four high accuracy universal inputs which may be used for both data recording and feedback to two PID control loops. This secure data recording device with accurate control is enhanced by a full color, ¼ VGA display to bring a crystal clear operator interface to even the smallest of machines. The nanodac recording functionality utilizes the secure data archival strategies and UHH file format developed by Eurotherm through years of recording expertise. Real-time and historical data are displayed on a crisp, clear display screen.
The nanodac also offers redundant data archiving strategies utilizing the 50 MB onboard Flash memory, removable USB port and frequent data transfer via FTP to any desired server location. The nanodac instrument can optionally provide two independent control loops which make use of the advanced Eurotherm PID control algorithm; this choice provides high performing and reliable control to any process. The PID control loops are augmented with one of the best auto-tune facilities available along with a host of complimentary features such as: overshoot inhibition, compensation for power fluctuations using power feed forward, and linear, fan, oil, and water cooling algorithms. The nanodac is a natural choice to eliminate the need to engineer separate data recording and PID control solutions saving on both cost and time.
