Get a quote

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. 

A1570 EMAT is dedicated to conducting ultrasonic thickness measurements by means of electromagnetic-acoustic transducers. The instrument is suitable for variety of applications, such as:

  • Automated and mechanized corrosion testing on pipelines and storage tanks
  • Thickness measurements on boiler tubes & heat exchangers
  • Ultrasonic measurements on high-temperature objects
  • In-Situ ultrasonic stress measurements
