ABB. Dundalk, Ireland, recently introduced its Weight xP extended profiling actuators. The state-of-the-art actuators help customers achieve the lowest possible cross direction variability and reduce cost. The latest generation of ABB's popular xP profilers, the new Weight xP actuators help papermakers meet even the most exacting product specifications. With robust design, proven components and unique technologies, Weight xP delivers precision and reliability, ABB notes.
"With the new Weight xP's technology, mills can achieve faster recovery from grade changes and process upsets that they need to keep productivity at high levels," says Steven St. Jarre, head of Sales and Marketing for ABB Quality Control Systems.
The Weight xP family of actuators includes the Slice xP, Dilution xP, and Coat Weight xP systems that are designed based on ABB's experience in applying actuators on more than 25 different manufacturers of headboxes and coaters.
The actuators feature patented and patent-pending technology that eliminates dependence on a physical position sensor, and allows the actuator to achieve its new position in one continuous and fast movement, reducing the time needed to make control actions. In addition, the power management scheme allows simultaneous movement of actuators at all times, even during flush cycles, global setpoint changes, or even if one power supply has failed, providing papermakers with the ultimate in reliability, ABB explains.
Slice xP, Coat Weight xP, and Dilution xP each offer advanced diagnostics for easy troubleshooting and increased system availability, as well as built-in monitoring of more than 60 different parameters, to predict an impending actuator failure long before it occurs, ABB adds.
