Ultrasonic Testing System

The high frequency (HF) ultrasound device consists of a scanning system with immersion basin, the external transmitter and receiver unit. Using the pulse-echo method, high-resolution interference points are detected on thin samples (depending on the material, up to a maximum of 5 mm) and visualized at the precise location using digital imaging. Among other things, it is used for testing the early damage markers delamination, blistering and rust on varnish layers. Furthermore, adhesion problems in adhesive and fiber composite systems can be detected.

Application Examples

  • Non-destructive testing
  • Damage analysis of thin components as well as welded and soldered joints
  • Detection of incipient corrosion attack on varnish-coated samples in stress test
  • Investigation of laminates, fiber, composites, bondings


Device Configuration           

  • Operating settings:
    • 0,01 to 200 MHz frequency range in broadband channel
    • Pulse repetition frequency up to 10 kHz
    • Scan area 500 × 500 mm
  • Test probe 15 MHz and 50 MHz
  • Reports as B-, C-, D-, F‑images
  • Low penetration depth
  • Highest resolution → lateral approx. 50 µm
