Linear Inspection Tool

A versatile freehand scanning solution for fast, simple and flexible inspections without the constraints of a scanner frame.

The wire encoder is fixed to the part and remains stationary allowing the operator to easily move the probe across the inspection surface.


Typical applications for the Wire Encoder include:

  • Pipelines and Vessels – Corrosion mapping, Bond testing on overlapping joints
  • Aerospace – In-service C-scans, Bond Inspection, Delamination or defect detection in composites
  • Wind Energy – Blade spar, leading and trailing edge bond inspection

Wire Encoders are compatible with the Phoenix C-Clamp which can hold any probe and wedge combination up to 55mm wide and is ideal for use with linear phased array probes for C-scan inspections.


Available with three snap fit mounting options: magnetic, vacuum or clamp. The Wire Encoder can be mounted anywhere close to the inspection site, permitting set up on or near to the component or around obstructions. The mounts can be used to fix the encoder upright, on their side or even inverted.


Wire Encoders can be used on an inspection area of upto 3m from a single position. This enables C-scan inspection in difficult to access areas.
