We are pleased to add Pulsec to our already robust line of non-destructive test solutions for aerospace, says Dave Jankowski, Business Leader of Eddy Current solutions at GE Sensing & Inspection Technologies. Pulsed eddy current technology allows rapid imaging of aircraft fuselage for corrosion, which means problems are detected and can be fixed more quickly in order to keep aircrafts flight worthy.
With a battery life of 6 hours and a weight of just 13 pounds, Pulsec is a truly portable instrument that can inspect difficult to reach places on an aircraft. Pulsec features a hand-held x-axis encoded, array probe to allow rapid surface inspection and direct imaging of large areas. Along with multi-layer sub-surface corrosion detection Pulsec can also be used for crack detection depending on the probe, scan direction and configuration settings.
The wide frequency and depth range of the Pulsec instrument, which uses PEC technology covered by several GE patents, is much greater than that associated with conventional eddy current, as more information is generated for post-processing for display or for further analysis. With this advancement there is no need to select a specific frequency for every inspection. Pulsec also provides easier and more reliable follow-up testing, as the single optimum frequency required for subsequent inspection of any corrosion or cracks detected by the initial Pulsec PEC scan can be easily identified and the relevant single element coil probe can be fitted to the instrument.
Pulsec has a high visibility TFT color screen to provide high quality imaging and with an internal memory of 1GB and a hard disk of 80GB, it offers powerful on-board real time analysis and data recording and storage. Data can be transferred via USB or Ethernet for post data analysis to improve POD and reports are generated with image capture at customer-selected intervals.
An advanced lift-off algorithm allows scanning in real world situations such as variations in paint thickness, surface roughness and other causes of lift-off and as with all eddy current equipment, inspections can be carried out with no need for direct contact with the material and with no need for couplant.
