LABORATORY SYSTEMS FOR
AIR-COUPLED ULTRASONIC TESTING
Ideal for non-destructive & coupling agent-free defect control for random samples
Monitoring Errors by Means of
When setting up new machines or making a change in the production process, it is a convenient method to check random samples within the new process flow for defects. Laboratory systems from yoUScan can test a wide variety of materials (wood, fibre composites, thin metal, etc.). In contrast to the inline systems, you can not only differentiate between OK/NOK, but with detailed tests it is possible to understand the effects of further changes in the production process on the material.
The yoUScan laboratory systems can work with the transmission method or the impulse-echo method. The transmission method, also known as sonic testing technology, tests the sound permeability of a medium or material as well as its interfaces. The different attenuation of the sound makes imperfections or defects visible with this method. With the impulse-echo method, on the other hand, the reflected sound is evaluated. Therefore, approximately twice the sound path is necessary & there are disadvantages with strong scattering & weakening of test media. However, the test object only has to be accessible from one side and the defect depths can be determined on the basis of the transit time differences.

3D display of C- & D‑scan
A spatial meander can be driven to record a sonic field. Any layer can be displayed using this particular measurement space.
Python Measured Data Processing
Loaded measurement data are transferred from yoUVision to a loaded Python module. After processing, these are taken over again & are available in yoUVision.
Time Gain Compensation (TGC)
A amplification curve can be defined in YV with which the HF signals are multiplied. This allows individual time ranges of the HF signal to be attenuated or amplified to different degrees.
With this wizard, important data of a transducer can be quickly defined and saved for reports in diagram and measured value form. These form the spectrum and freely definable plots in x- and y‑direction.
Library of functions used to configure the measuring card as well as to retrieve the measurement data. Allows the development of own
applications including GUI as well as integration into
A signal applied to the external trigger input starts the transmission of the transmission code & the recording of the measurement data. The delay between the trigger edge at the trigger input and the start of transmission & recording is max. 800 ns (typ. 550 ns). The jitter is max. 60 ns (typ. 45 ns).
