Spherical Projectors Model PyS-25
Spherical Projectors Model PyS-25
The PyS-25 is a spherical transducer for acoustic emission with hemispherical directivity, and high efficiency. This transducer is particularly suited for underwater acoustic communication and positioning and can achieve long range communication thanks to its high sensitivity.
