TOFD Transducers

Extra-flat TOFD for CRD* inspection



Detection of axial defects

Detection of circumferential defects


Application

Reactor vessel cover penetration tubes inspection

Principle

The extreme fineness of the probes, combined with their curvature, allows them to be inserted between the control bars and the guide tubes.
The transducers can thus inspect the guide tube in TOFD mode.

The orientation of the transducers enables longitudinal or circumferential defects to be detected.

Advantages

Inspection feasibility, sensitivity, bandwidth

General Characteristics

These transducers are adapted individually to the inspection constraints, and in particular to the handling, plating and coupling mode.

  • Thickness < 2.5mm (down to 1.5mm)
  • Nominal frequency: 4 to 5MHz
  • Adjustable PCS
  • Refracted angle range: 45 to 70°
  • Radius of curvature: 70mm (typical)
  • Longitudinal or circumferential orientation
  • Integrated cable

Options

  • Water distribution device for the coupling
  • Halogen-free
  • Mechanical plating solution
  • Steering
  • Transducer at 0° for thickness measurement
