Application Notes
Aircraft Maintenance Inspections
Aircraft NDT inspectors are often expected to utilize multiple nondestructive testing disciplines in their inspection, such as eddy current or remote video, in addition to ultrasound. The EPOCH 6LT flaw detector is durable, compact, and easily fits in a bag with other equipment. The user interface is intuitive, so even if you don’t operate ultrasonic flaw detectors regularly, you can be confident in your inspection results. Since many newer aircraft skins and components are constructed with difficult-to-inspect composite materials, the EPOCH 6LT flaw detector includes the pulser power and signal-to-noise ratio necessary to solve these challenging applications.
Features for Aircraft Maintenance Inspections
The EPOCH 6LT flaw detector features the same high dynamic range pulser/receiver as the EPOCH 650 flaw detector, including:
- PerfectSquare TM tunable square wave pulser
- Digital high dynamic range receiver
- Eight (8) 100% digital filter sets
- Pulser voltage from 100 V to 400 V
- Five customizable digital measurements
Standard Flaw Sizing Software
- Dynamic DAC/TCG: Compares signal amplitude to a DAC curve or reference echo amplitude; the DAC version includes standard, custom DAC warning curves, and 20-80% views
- DGS/AVG: Compares signal amplitude to a DGS/AVG diagram, which illustrates the relationship between echo height, flaw size, and distance from the transducer
