Intended as a replacement for the HemiPlus moisture sensor, the HPIR is designed to improve the performance and reliability of both new and existing ABB QCS systems.With HPIR, papermakers can have more confidence in the precision of their moisture measurement. They can achieve tighter CD control, and faster start-ups and grade changes, ABB writes in a press release. Papermakers can shift their moisture targets closer to acceptable quality limits, saving energy and reducing fiber costs, while remaining within the paper grade’s quality specifications.The increased precision comes from several technical breakthroughs in the design that significantly increase the signal-to-noise ratio and the measurement rate of the sensor. As a result, the sensor can resolve moisture streaks as narrow as four millimeters. With a measurement rate of 5,000 per second, the sensor provides precision measurements, even as paper machines continue to become wider and faster.
