DFR and K-PEN Delay Line Transducers

DFR Replaceable Delay Line Transducer

  • Excellent near surface resolution
  • Replaceable delay line—long life and versatility
  • Higher frequencies improve resolution and small flaw detectability
  • All models have side mounted Microdot connector.
  • Custom configurations are available by special order

K-PEN Replaceable Delay Line Pencil Probe

  • Focused, high resolution pencil probe
  • Interchangeable delay lines, two tip diameters (.065 inch / 1.7mm & .090 inch / 2.3mm)
  • Extremely small contact area
  • Tightly curved surfaces, such as turbine blades
  • Wall thickness measurement from the bottom of an external pit
  • Straight, right angle and 45° handles
  • Straight model has removable handle
