TRECSCAN® is an advanced transient eddy-current scanning system using probes containing Hall sensors.

The system now has recognised potential for the detection of deep corrosion and cracks in ageing aircraft fleets.

There are significant benefits to be realised from the use of transient eddy-currents in terms of reduced inspection time and ease of acquisition and analysis of the data.

Large areas of structure incorporating multiple variations in thickness can be scanned without the need for any probe or set-up changes.

In addition, the use of a Hall sensor rather than a coil as a magnetic field detector improves the spatial resolution and detect ability of deep defects.
