Tubing Probes

RFT Single-Driver
Flexible Probes

Remote field testing is the best way to inspect ferromagnetic heat exchanger tubing material such as carbon steel.

Welded on a flexible stainless steel shaft, each driver and receiver modules are designed to be resistant and waterproof to manage a whole heat exchanger U-bend tube in a single pass. It remains limited in terms of detection in the bend section, but it can manage tight radius bend.

The probes are particularly well suited to detect common defects (corrosion, erosion, wear, pitting) and to inspect the ferromagnetic tubing in feedwater heaters, heat exchangers, and piping.


  • Optimized for absolute signal analysis
  • Waterproof and very resistant to wear
  • Low friction noise
  • Manage U-bend (180°) radiuses as small as 88.9 mm (3.5 in)
