Eddy current flaw detector 9231641

for aeronautics

Overview
The flexible shaft of these surface probes can be shaped to perform inspections of areas that are very difficult to reach. The small diameter housing and small coils of these detachable copper-shaft surface probes are built for high frequencies, making them ideal for surface-breaking crack detection.

Advantages

• Excellent for small defect detection.
• Best option for areas inaccessible to standard probes.
• Bendable shaft enables inspection around fasteners.
• Available with Powerlink™ technology.
• Wide selection of lengths and drops.
• Available with bridge or reflection configuration.

Applications

• Through-paint inspection of aircraft rivets.
• Aircraft structure, unit, and engine inspection.
• Through-paint detection of stress corrosion cracking in stainless and carbon steel.
• Surface crack inspection of manufacturing and transportation equipment.

Absolute bridge type probes

• Internal reference coils ensure the best match to the test coil when using a Triax (Fischer™*) or Powerlink™ connector.
• Shielded coil for higher resolution.
• Detect cracks in all directions.
• Probe-type commonly used worldwide.
• Cost-effective option.

Reflection type probes
Also known as send-receive or driver-pickup probes

• Provides a similar response to the absolute bridge probe.
• Available with stacked or concentric driver and pickup coils.
• Enables crack detection in all directions.
• Withstands variations in temperature.
• Operates over a wide frequency range.
