EMAT Technology
Research and Development

EMAT Technology and our research partners are continually
developing innovative EMAT solutions to complex inspection
problems.  Examples include down hole tools, in-line inspection
pigs, short range axial guided wave tools.
EMATS are the ideal tool for online NDT inspection.

The EMAT transduction-by-induction process has several
advantages for NDT.

  1. Non-contact. Depending on the required wavelength of the
    guided wave used for inspection  an air gap next to the
    inspected surface can be maintained, thus no coupling
    liquid or grease layer is present to restrict the range of
    temperatures or inspection speeds available for testing.  
  2. Inspection material is part of the transducer.  The
    transduction process takes place within the surface of the
    component allowing the time-of-flight (or phase) of the
    ultrasonic wave to be measured with great accuracy so that
    dimensions and physical properties of materials can be
    used for quality assurance purposes.
  3. Guided waves.  The shape of the coil and the direction of
    the magnetic field allow the type (shear or longitudinal) and
    direction of the propagation of the wave to be controlled by
    the transducer design.  Special wave types (e.g., shear
    horizontal, Lamb, Rayleigh) are readily available to satisfy
    unusual inspection problems.
  4. Flexible design.  Coils that are large or contoured to fit odd
    shapes are inexpensive and extend the range of part
    geometries available for inspection.
