The requirements on ultrasonic inspection systems are steadily rising with the advance of the technological evolution known as »Industry 4.0« –a term that describes a multitude of technical measures to enable controlled processes instead of inspected processes. Requests include the adaptability to a large number of different application scenarios, steadily increasing sampling and data transfer rates while concurrently enhancing signal quality. Furthermore, the flexible and prompt integration of the inspection systems into existing customer production lines is essential.


UNIUS is Fraunhofer IZFP‘s solution for technical challenges addressed to current single-channel ultrasound inspection systems.



UNIUS is a versatile, high-performance, single-channel ultrasound board covering a multitude of customer applications (defect inspection, prove of purity level, etc.) out of the box. The system is available as benchtop model and as a mobile and sturdy variant in form of an industrial notebook compliant with the IP65 protection rating. Additionally, UNIUS can easily be integrated into customer-specific systems for manual or automated inspections by using the ITK software interface.

The option of application-specific firmware adaptations tailored to the customers’ demands completes the UNIUS service portfolio.
