Pneumatic conveying systems provide a convenient and effective way of transporting solids over modest distances. One of the biggest problems concerns the way bends wear out when abrasive materials are conveyed. At present there is no direct method for monitoring the bend wear and condition. This paper presents a novel method for bend condition monitoring based on cross-correlation techniques.
