The magnetostrictive sensor technology for long range guided wave testing and monitoring of structures

A technical background on and applications of a guided wave technology called the magnetostrictive sensor are described. The magnetostrictive sensor technology is for long range global testing and condition monitoring of structures such as piping, plates and steel cables. For long range testing of piping in processing plants, such as refineries and chemical plants, the magnetostrictive sensor system, including the probe, instrument and data analysis software, is matured for use in commercial testing services. Capabilities of the present magnetostrictive sensor system for pipe testing are presented together with an example of testing data and their analysis.
