Each Basis Weight Sensor measures the total mass and air mass between the source and detector. In addition, the temperature of this critical area is precisely monitored and controlled. These techniques keep the air column stable during dynamic process conditions, making Basis Weight measurements the most accurate and reliable in the industry.
Today’s producers of quality grades must meet stringent customer demands for uniform paper, both in the machine-direction (MD) and cross-direction (CD). Accurate measurement and control of basis weight is key to meeting these customer quality specifications. Basis Weight Sensors from ABB offer papermakers unparalleled accuracy and streak resolution, providing detailed product information for optimum MD and CD weight control.
Basis Weight Measurements feature a revolutionary, compact design and superior measurement performance in even the harshest environments. ABB’s Sensor family includes krypton- and promethium-based weight gauges that are application optimized to measure a wide range of paper grades. These sensors combine high signal-to-noise ratios with millisecond response time and 32-bit signal processing. The result is advanced, online weight sensors with laboratory accuracy.
