Guided Waves and MsS system

    Long-Range Guided Waves represent one of the latest NDT techniques and the MsS is the only Guided Wave Inspection / Testing instrument based on the magnetostrictive phenomenon. Other Guided Wave sensors use arrays of piezoelectric elements to generate and receive Ultrasonic Guided Waves. 
        

  
  The MsS Equipment for Guided Wave Testing will be available in Pisa, Italy for demonstrations or rental or other requests from interested companies across Europe.


    Magnetostrictive sensors (the same technology is used in sonar or airbag crash sensors) present a series of unique characteristics that offer them a number of advantages over their piezoelectric counterparts.

    In a few words, the MsS can do everything and more of what the other GW technologies can do and do it better for at least 7 reasons:

  1. Performs long range screening of inaccessible pipelines: 300 meters can be inspected from a single location in ideal conditions; inspection range can be wider than that of piezoelectric collars due to the very good SNR that is a characteristic of non-segmented GW generators like the MsS.
  2.  Suitable for pipe inspection and more: With only one instrument, a multitude of different inspection applications are possible: pipe inspection, lighting poles (even with non-circular section) fuel tanks, plate-like structures, composite materials, heat exchanger tubes, boiler tubes,  wire rope, anchor rods etc.
  3.  Suitable for long-term monitoring and more: The sensor design (less than a few millimeters thick) makes it easy to install it permanently under the normal pipe insulation;
  4.  The inspected pipe temperature range is much wider than in the case of piezoelectric transducers: (-90°C up to 500°C) makes it suitable to a wide range of applications from the cryogenics industry to high temperature refinery applications.
  5.  Large pipe diameters can be inspected and even more: there is no limit in the pipe diameter: large probes can be easily produced on site or the simple sector probes can be used; there is no need to buy many different expensive collars for each pipe diameter.
  6.  A wide range of test frequencies are possible. Typically, GW collars are set for one optimal frequency like 40kHz for example. This is not the case for the MsS. The probes flexibility makes them easy adaptable to many optimal frequencies within a wide range (from 8 kHz up to 256kHz) without the need of buying additional expensive collars.
  7.  GW Analysis trains inspectors for GW data interpretation, so that they can operate independently most of the time with no need of sending their inspection data to a third part for interpretation. However, for cases of high complexity signals, on client request, GWAnalysis can offer its professional support.
