Eddy current depth penetration

Are a dedicated manufacturer of eddy current ndt equipment and accessories including a vast range of ec weld probes, et weld probes and ect weld probes and are the ‘go to’ company for all your eddy current ndt solutions. The depth at which eddy current density has decreased to 1/e, or about 37% of the surface density, is called the standard depth of penetration (. At three depths (3. Will endeavour to find the solution that best fits the clients specific needs.

Phase angle and impedance

The word ‘standard’ denotes plane wave electromagnetic field excitation within the test sample (conditions which are rarely achieved in practice). Permeability is, also, not uniform.
