(Thickness Measurements Through Coatings and Insulation)
Pulsed Eddy Current is a unique corrosion survey method that allows ferrous objects to be surveyed without the need to make contact with the surface (in contrast with ultrasonics). This means that measurements can be performed on objects covered with insulation, asbestos, fireproofing, concrete or coating. The high costs for removal of insulation can therefore be avoided. Scaffolding can be reduced by using rope access or by mounting the measuring sensor on an extension pole.
