Ultrasonic paper testing


I am interested in study ultrasound propagation in paper by contact mode.

In the beginning I am interested only in the detection of the signal trough the paper (Lamb waves or similar) and velocity measurements in different directions.

I have knowledge of a commercial equipment for this propose that use bimorph ceramics.

I want to know if anybody knows a transducer for this application.


Best regards

Re: Ultrasonic paper testing
By using the forum search I could find two old forum topics that dealed with Ultrasonic paper testing.

measuring paper

Product Spotlight

FMC/TFM

Next generation for Phased Array UT is here now with FMC/TFM! Have higher resolution imaging, impr
...
oved signal to noise ratio, characterize, size and analyze defects better with access to several wave mode views and save raw FMC data for higher quality analysis.  Some of the benefits are:
  • Beautiful Image! Easier to understand what you're looking at
  • Completely focused in entire image or volume
  • Much easier to define setups before inspection
  • Easier to decipher geometry echoes from real defects
  • Oriented defects (e.g. cracks) are imaged better
  • See image from different wave modes from one FMC inspection
  • FMC data can be reprocessed/analyzed without going back to the field
