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

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.

Olympus absolute bridge type probes give a clean and strong signal as shown.

Reflection Absolute

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.

Olympus reflection absolute type probes give a clean and strong signal as shown.
