Behind a protective acoustic window
Vessels operating in arctic waters need special attention on
transducer installation. Floating blocks of ice may damage even
a flush mounted transducer face. For this situation Simrad offers
‘’arctic tanks’’ in different sizes.
The transducer shown in the figure below is mounted inside the
tank behind a strong acoustic window which could be made of
polycarbonate. The tank is oil filled.
