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 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.
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.
