Pencil Surface Probes

Advantages

• Excellent for small defect detection.
• Good stability on flat surfaces.
• Available with Powerlink™ technology.
• Broad selection of frequency-ranges.
• Wide variety of coil configurations available.

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.

Reflection type probes

Also known as send-receive or driver-pickup probes

• Suitable for small defects, such as fatigue cracking.
• Less drift than bridge probes.
• Directional sensitivity.
• Withstands variations in temperature.
• Driver and pickup coils can be separately optimized for their intended purpose.
• Wider frequency range, as driver coils do not need to be balanced to the pickup coils.

Evident reflection differential type probes give a clean and strong signal as shown.

• 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.

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

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.
• Withstand variations in temperature.
• Operates over a wide frequency range.

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

Bridge differential probe

• Suitable for small defects, such as fatigue cracking.
• Directional sensitivity.

Evident bridge differential type probes give a clean and strong signal as shown.
