A nondestructive testing technology called eddy current array (ECA) is capable of driving numerous eddy current coils that are positioned next to one another in the same probe assembly. In the probe, ...

Heat exchanger systems are designed with practically no risk of failure when they are new. In fact, some components have such nominal exposure that they are not apt to fail for years, if ever. After ...

Eddy current testing has been used for at least 50 years to inspect conductive parts for surface imperfections such as cracks or scratches. Fundamentally, the technique is comparative—it only ...

Eddy currents are specialized electric fields that are generated in the presence of a magnetic field and are often seen as a secondary field. An Eddy current can be produced by both electromagnets and ...
