OEM Ultrasonic Pulser-Receiver frontend unit for couplant-free thickness measurements by means of electromagnetic acoustic transducers
A1570 EMAT is the high-end EMAT data acquisition frontend unit designed for integration in automated inspection setups & scanning systems (crawlers) for couplant-free thickness measurements on metallic objects. The pulser and receiver of A1570 EMAT can drive the regular EMAT transducers with permanent magnets as well as the novel EMAT probes with pulse magnetization. The instrument possesses an integrated battery and wireless data interface for stand-alone operation.
With the well-documented SDK the user is enabled to develop his own software applications for customized inspection tasks.
