Sonar Systems
"Sonar" means sound navigation and ranging. These are systems for detection,
position finding, and navigation under water. The application for such systems
range from single small transducers for pleasureboats which detect fish or obstacles
to commercial systems in large ships which detect the depth of the water and collect
all important data's regarding the trawl as for example opening of the net, distance
to the ocean-bottom, distance to the ship, symmetrie and filling rate of the trawl.
For the different systems, piezoceramic transducers with diversified dimensions are used, covering a frequency range from 5 kHz to 10 MHz. Some systems use the same piezoceramic transducers for transmitting and receiving. Others use different ceramic transducers for transmitting and receiving, with some designs working over a long distance.
Large ships use transducer arrays, which consist of a high number of piezoceramik elements. These elements can be driven separately. and electronically delayed. This makes it possible to create an electronic beam deflection.
Designs: Round disk, cylinder, rectangular plate, circular segment, spherical segment and other special forms
Material: SONOX® P 4, SONOX® P 5, SONOX® P 8
