EMAT Adapter GS2020

The EMAT Adaptor GS2020 provides a means for NDT inspectors to benefit from the advantages of non-contact EMAT transducers for pulse-echo flaw detection and thickness gauging, without the large capital outlay of replacing existing piezoelectric based flaw inspection systems and thickness/corrosion monitors.

The EMAT Adaptor GS2020 provides: 

  • A bridge between an EMAT probe and a flaw detector designed for piezoelectric transducers.
  • Low power averaging electronics, such that the signal-to-noise performance of the EMAT measurement is dramatically improved.
  • Automatic gain control (AGC), increasing reliability and inspection speed whilst eliminating the need for operators to adjust EMAT stand-off or the gain setting on the flaw detector.
  • Compatibility with almost all standard flaw detectors ― contact us for more information or a free trial with your flaw detector.  

The GS2020 is designed to work with modern NDT inspection systems with a suitable EMAT (provided as part of the package). It has sufficient signal strength and resolving power to operate on:

  • Oxide coated ferritic steel components
  • Non-oxide coated ferritic steel components 
In certain circumstances, measurement of austenitic stainless steel is possible as shown in the figures below:

Sonemat's GS2020 EMAT adapters are sold with a standard bulk shear wave EMAT ( HWS2225-GC) for £2700.
