Analytical equipment/New portable five-axis ultrasonic scanning system

摘要

Panametrics, Waltham, MA, USA, has developed a new portable ultrasonic scanning system (NDT FreeScanner) offering encoded C-scan imaging in a hand-activated compact unit and introduced Epoch 4B, the latest addition to its family of ultrasonic flaw detectors, with a series of new advanced measurement features based on the proven Epoch 4 platform. Features. Combined with high-resolution motion positioning, superior ultrasonics and data acquisition software, this portable system is a powerful and affordable imaging tool for many testing applications. The five correlated axes of the scanner allow the operator to freely move the transducer holder in virtually any position within the circular range of the arm. A series of optical encoders inside the arm joints accurately tracks the spatial position of the transducer to provide fully encoded planar C-scans on flat or contoured surfaces.
