Rotating Probes - Reflection

Differential Rotating Probes: For internal diameter inspection of fastener holes, countersinks and counter bores. 
Specification: 
  • Probe diameters from 1.6 to 50mm, available in 0.01mm steps.
  • Fischer connector to ETher NDE Small and Large drive also compatble with Hocking, GE, Rohmann and Forster drive units.
  • Frequency range from 200kHz to 2MHz.
  • Comes in Rigid Stainless Steel and Delrin Flexible options. 
Notes: When ordering Rotating Probes 0.1mm is automatically taken of probe diameter during manufacture, this should be good for typical hole condition and manufacturing tolerances. Where tolerances are poor, allow for greater clearance. 

Example: To inspect a 12.7 (1/2”) hole a 12.7mm dia. probe should be ordered which will be manufactured to a 12.6mm dia..

Internal Diameter (ID) Probes - Bridge

Differential ID Probes: For internal diameter tube inspection, ideal for inspecting tubular heat exchangers. 
Specification: 
  • Probe diameters from 7.5 to 150mm, available in 0.1mm steps.

  • Cross axis and driver/pickup optons also available on request. 
Notes: When ordering ID probes allow 0.8 to 1.5mm less than the tube diameter. This should be good for typical tube conditon and manufacturing tolerances. Where tolerances are poor, allow for greater clearance. Tape can be used were necessary to reduce probe ‘wobble’.

Low Frequency (Spot Face) Probes, Straight and 90°

Reflection Sub Surface Probes: for general purpose inspection of sub-surface corrosion and flaws. This probe has excellent depth penetration making it ideal for multi-layer inspections.
