ABB Introduces New Infrared Moisture Sensor for Paper Industry

ABB, Dundalk, Ireland, has introduced a new High-Performance Infrared (HPIR) moisture sensor for its QCS800xA Quality Control System (QCS). 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.

HPIR provides tighter CD control and faster startups and grade changes. Papermakers can shift 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 4 mm. With a measurement rate of 5,000 per second, it provides precision measurements, even as paper machines continue to become wider and faster,

ABB says. HPIR does not require liquid cooling and it is the only moisture sensor on the market with no continuously-moving parts. The modular design allows for easy field replacement of modules, avoiding factory repairs and eliminating the need to stock a complete spare sensor. More information is available online.
