Technology

Our sensor products use cutting-edge ultrasonic technology, in which specially configured piezoelectric actuators generate guided acoustic waves (GAW). This allows us to offer precise monitoring and quality control through advanced ultrasonic technology. These waves, which can be excited in a wide frequency range of around 200 kHz to 1 MHz, travel completely contactlessly (non-invasively) along the substrate and enable highly sensitive and precise measurements.

Our technology focuses in particular on Rayleigh waves and Lamb waves:

• Rayleigh waves are surface-bound waves that travel along the surface of a solid body.
• Lamb waves are guided waves that occur in “thin plates,” where the wavelength is in the range of substrate thickness. They can appear in various fashions.

Through mode conversion (the conversion of energy), both Rayleigh and Lamb waves continuously emit energy from the solid body into an adjacent medium such as water or oil. This exchange of energy between the substrate (e.g. slide ring, bushing) and the fluid (e.g. lubricating film) makes it possible to draw conclusions about its condition.

A particular advantage of our technology is real-time monitoring. The continuous recording and analysis of acoustic signals makes it possible to provide immediate feedback on the status of the monitored system. This makes a significant contribution to process and product quality by allowing potential problems to be identified and resolved at an early stage.
