Abstract
Vibration sensors can be used in paper making systems and methods to determine various aspects of the paper making operation. Vibration sensors, for example, positioned on cleaning blades configured to clean various deposits off of rollers in a paper making system can output vibration data that can be indicative of the vibration of the blade. The vibration data can be analyzed in order to characterize the cause of the vibration and/or the location of the vibration within a paper making system. If the vibration data satisfies a predetermined condition, a corrective action can be initiated. Different corrective actions can be initiated based on the characterized cause and/or location of the vibration in order to effectively improve the operation of the system while minimizing costly system shut downs and major maintenance.
