TCM Position Encoder

Precise Position Tracking for Flexible Eddy Current Inspections

Inspect surfaces faster. Document results with precision. The TCM Position Encoder enhances mobile eddy current inspections with the TCM by providing precise optical position tracking. It enables accurate localization of inspection signals while visualizing the area already inspected in real time.

Thanks to its optical sensing technology, the Position Encoder captures movement freely in both the X and Y directions. Unlike conventional direction-dependent position tracking systems, inspection surfaces can be scanned flexibly without following a predefined path. This enables faster inspections, complete surface coverage, and precise documentation of the inspection process.

The Position Encoder can be used with all TCM standard pencil probes with a probe diameter of up to 14 mm, as well as with TCM Array Probes. This makes it suitable for a wide range of mobile eddy current inspection applications – from manual crack detection to large-area inspections using Eddy Current Array technology. Its simple mounting design allows existing probes to be retrofitted quickly, extending their functionality without additional inspection effort. For high-resolution array probes, the Position Encoder is already integrated.

Product highlights

Your advantages at a glance

  • Direction-independent position tracking: The optical sensor technology allows unrestricted movement in any direction, enabling fast and convenient surface inspections without a predefined scanning path.
  • Flexible surface inspection: Move the probe freely across the entire inspection area in both the X and Y directions, adapting the inspection path to the geometry of the component.
  • High-precision position tracking: The optical technology records the inspection path with an accuracy of 1% of the traveled distance, enabling precise signal localization.
  • Reliable surface coverage: The inspected area is continuously visualized, supporting complete, traceable, and reproducible inspections.
  • Suitable for reflective surfaces: The optical position tracking system operates reliably even on challenging reflective surfaces.
  • Versatile retrofit solution: Compatible with straight TCM standard pencil probes and all TCM array probes, except high-resolution array probes where the Position Encoder is already integrated.
  • Seamless TCM integration: Simple USB-C connection and direct use within the TCM software for precise position tracking and signal visualization.
