Semi-Flexible ECA Probes

Semi-flexible probes come with all the great features of rigid probes, but they can also easily bend to perform axial scans on convex and concave geometries with height variations along a single axis (such as pipes and floor plates).


  • Rugged casing
  • Retractable contact pins
  • Three sizes: S, M, L
  • Compatible with our standard, click-on encoder
  • Wide range of configurations to suit your specific application needs


The probes also come in a wide variety of frequency brackets, number of coils, and three casing sizes: small, medium, and large.


  • Flexible contact surface that adapts to height variations
  • High uniform sensitivity
  • High resistance to wear and tear



  • 26–128 mm (1.02–5.04 in) depending on model
Penetration (stainless steel/aluminum)
  • 3–6 mm (0.12–0.24 in) depending on model
Minimum detectable crack length
  • 0.5–1.0 mm (0.02–0.04 in) depending on model
