Air-Coupled Transducers

AIR-COUPLED TRANSDUCERS

  • The air-coupled ultrasonic technique has shown to be very efficient and fast for testing large areas. The air-coupled technique avoids coupling problems like bubbles in water, but the large acoustic mismatch between solids and air must be solved with special transducers, a powerful excitation as well as hardware and advanced software signal processing.

     

    DASEL offers a broad range of ultrasound air-coupled transducers with the following features:

     

    - Connectors: BNC / SMB / Lemo00.

    - Housing: anodized aluminum.

    - Electric Matching with Airscope series

    - Crown to protect the radiant surface

    - Each pair of transducers is identical and can be used without distinction as a sender or receiver. All transducers can also work in pulse-echo mode.

    - Compatibility: The transducers have been successfully tested with DASEL devices (Airscope TT/MX/PA).
