Air Coupled Ultrasonic Inspection Technique

For the air coupled ultrasonic inspection technique (contact-free, no couplant necessary, no wetting of the specimen) new 8-fold array probes for different frequencies (120, 200, and 300 kHz) are available now (see figures 1-2). They reduce the inspection time of a 1 m² specimen from 28 minutes to 4 minutes. With our new ultra-low-noise amplifier AirTech 4050 the signal-to-noise ratio of our probes can be increased up to 4 dB. The amplifier can be integrated in the case of the probes AirTech 50-R, AirTech 75-R, AirTech 120-R, AirTech 200-R, AirTech 225-R and AirTech 300-R. Typical results with the 300 kHz probe AirTech 300-R for a 5.3 mm CFRP inspection are shown in figure 4.

Service

Additional to our products we provide an extensive training offer for the imaging ultrasonic inspection technique which can be adjusted to your inspection task. Furthermore, a calibration of our systems can be performed on-site.
