NP800 scanner from ABB is for QC

Zurich, Switzerland-based ABB offers its Network Platform 800 (NP800) which, it says, is a completely new scanner design which provides pulp and paper customers with a perpetual foundation on which to evolve their ABB quality control systems (QCS).

NP800 is a high-performance scanner right-sized for today’s small-to-mid size paper machines of up to 6.2 m (244 in.) sheet width. ABB says that when combined with its paper sensors and controls, NP800 is a critical component of the QCS system for improving paper quality, optimizing paper machine stability and improving process efficiency.

NP800’s combination of powerful processing and real-time data acquisition provides precise sensor and frame co-ordination, fast signal processing and world-class measurement accuracy.

ABB has used its extensive pulp and paper product and service experience to design a scanner for easy expansion, robustness, reliability and serviceability. All system electronics and moving parts are fully integrated into the end columns and completely accessible from off the paper machine for easy and safe maintenance. No water cooling is required for either the scanner or any of its sensors. These features minimize installation down-time, start-up requirements and utility costs - reducing overall system lifecycle costs.

NP800 is a robust, reliable and stable platform, consisting of reinforced carbon steel A-beam construction with rigid end-columns for superior vertical, horizontal and torsional rigidity. This stable structure is critical for the precise alignment of sensor source and detector heads in harsh environments without the need for measurement profile compensation. The NP800’s smooth exterior design — with no external openings, covers, exposed hardware or cables — minimizes the possibilities for external contamination.

Integration with ABB’s 800xA and AC450-based QCS systems is supported along with a full range of engineering tools for configuration, monitoring and local and remote diagnostics. On-board diagnostics include spectral analysis capabilities that can provide further process insight. By studying the frequency of disturbances in the paper machine, changes in the performance can be linked to process upsets, helping mills to identify and eliminate sources of variation.
