Eddy current probe

for surface inspectioncrack detectionstainless steel

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. Evident 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.
