The "Ultrasonic sensors and methods" workgroup of Fraunhofer IKTS at the Dresden Klotzsche site is in charge of methodical planning and simulation-based optimization of ultrasonic-based test methods as well as their implementation in devices and equipment. The latter is done primarily based on the institute’s own PCUS® pro-Plattform. The devices and software of the PCUS® pro family are developed by the groups "Electronics for testing systems" and "Software for testing systems". If required, highly sensitive and reliable ultrasonic probes and sensors for special applications complete the platform. These are designed and manufactured in the institute’s own lab.
