Abstract: The present invention allows for the fabrication of an EMAT system that eliminates static charge impulse noise. The EMAT system includes an EMAT, wear layer, and magnet. If the wear layer is made slightly conductive, the static charges slowly bleed off rather than build up to cause impulse discharges. This semiconductive wear layer does not attenuate the EMAT signals by introducing any additional distance between the EMAT coil and the conductive piping or by introducing any conductive material between the EMAT coil and the conductive piping. In the preferred embodiment, a wear layer of UHMW (ultra high molecular weight) polyethylene with a surface resistivity of about 10,000 ohms per square is utilized. The conductive UHMW polyethylene still acts as a wear layer, but now also acts as a semi-conductive static-dissipative interface between the EMAT coil and the piping.
