Overview

Detachable stainless steel straight shaft surface probes have a small-diameter housing and coils built for higher frequencies. They are usually used for surface breaking crack detection. This straight shaft design is the standard pencil probe style.

Advantages

  • Suitable for small defect detection.
  • Ideal for inspecting the bottom of holes that are in line with the opening.
  • Easy-to-handle pencil shape.
  • Available with Powerlink™ technology.
  • Wide range of lengths offered.
  • Available with bridge or reflection configuration.

Applications

  • Bottom of holes in aircraft piston housing.
  • 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.
