Eddy current flaw detector 9216204.00

for aeronautics

Description

The 90-degree Right Angle Surface Probe is a detachable-shaft eddy-current surface probe designed for inspection in restricted-access zones and around fasteners. It features a small-diameter housing and compact coil optimized for higher-frequency inspection of surface-breaking cracks.

Advantages

• Suitable for detecting small surface defects.
• Accesses areas unreachable with standard straight probes.
• Drop geometry enables inspection around rivets and fasteners.
• Available with Powerlink™ connectivity.
• Offered in multiple shaft lengths and drop sizes.
• Available in bridge (absolute), reflection (send-receive) or bridge differential configurations.

Applications

• Through-paint inspection of aircraft rivets.
• Aircraft structure, unit and engine inspections in aerospace maintenance.
• 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 provide close matching to the test coil when used with a Triax Fischer or Powerlink™ connector.
• Shielded coil construction for improved resolution.
• Detects cracks in all orientations.
• Widely used probe type with cost-effective performance.

Reflection type probes (send-receive / driver-pickup)

• Produces responses comparable to absolute bridge probes.
• Available with stacked or concentric driver and pickup coil arrangements.
• Enables multi-directional crack detection.
• Stable performance across temperature variations.
• Operates over a wide frequency range.

Bridge differential probe

• Designed for detection of very small defects such as fatigue cracks.
• Provides directional sensitivity for oriented defect detection.
