Optimization of NDT Sensor Probe One of the most critical design decisions in any NDT/NDE problem is the design of the probe and its suitability for detecting particular types of defects. Starting from a model based on the WFNDEC Eddy Current Benchmark #2, OptiNet was used to determine the optimal coil geometry and frequency at which the inspection should be performed.

TEAM problem 15 - A Problem in Nondestructive Evaluation TEAM Problem 15 looks at the inversion of eddy-current data and the reconstruction of flaws in electromagnetic nondestructive evaluation (NDE). The model used is one of a circular coil moving along an aluminum plate that contains a slot. This gallery page demonstrates how MagNet can be used to calculate the resistance and inductance of the driving coil at various positions.

TEAM problem 27 - Eddy Current NDT and Deep Flaws The 3D Flaw model used in this example consists of a stationary coil over a sheet of aluminum that contains a screw hole. Inside of the screw hole, a flaw is to be detected by two Hall effect sensors, which are used to measure the horizontal differential flux density. MagNet's 3D Transient solver correctly models induced eddy currents inside the aluminum plate, after the current in the coil is turned off.

TEAM Problem 8 - Coil Above A Crack In this example, MagNet is used to analyze a non-destructive testing (NDT) problem with eddy currents. The comparison between the experimental results of TEAM Problem 8 and the simulation results obtained from MagNet, demonstrates how our low frequency electromagnetics simulation software can be used to accurately deal with NDT problems.

Variable Reluctance Sensor Variable reluctance sensors are used to measure position and speed of moving metal components. This sensor consists of a permanent magnet, a ferromagnetic pole piece, a pickup coil, and a rotating toothed wheel. As the wheel rotates, the reluctance of the flux path through the coil changes, which results in a change in voltage that is measured by an external circuit.

WFNDEC Benchmark #2 - Eddy Current Inspection of Inconel Pipe The World Federation of Non-Destructive Evaluation Centers (WFNDEC) publishes benchmark problems for Non-Destructive Evaluation and Non-Destructive Testing (NDE/NDT) applications. The Second Eddy Current benchmark involves the inspection of an Inconel pipe using an internal pancake coil situated with its axis perpendicular to the axis of the pipe. Small defects of various depths in the external wall of the pipe are scanned in the axial and circumferential directions. Defects are detected as a change in the impedance of the coil.
