Device for pressure -, sound, - and vibration, as well as german patent document 199 23 087.0 filed

摘要

A device for measuring pressure, sound and vibration, especially for analyzing flow on missiles or airplanes is provided with a sensor device (3) for picking-up pressure or sound waves. Said sensor device is linked to a structure (2) of the part in order to measure the forces acting on the surface (11a, 12a) of said part. The sensor device (3) is arranged entirely inside the structure (2) of the part or on the rear side of the surface (11a) of the part. In particular, the sensor device comprises a piezoelectric film, which is located beneath the surface (11a) of the part.
