Arctic tanks are fitted with special purpose acoustic windows that protect the transducer face.
The acoustic window is normally manufactured using polycarbonate.
The tank is filled with fluid that consists of 20% propylene glycol and clean water. This fluid is well suited for this purpose. It contains no gas bubbles and is non-corrosive.
Using the mounting ring
This large circular is transducer is designed to be mounted using the integrated flange and a mounting ring.The mounting ring is welded to the hole prepared for the transducer. Bolts through the transducer flange into the mounting ring will secure the transducer in place.
NoteMake sure that the "Forward" direction on transducer points in the forward direction of the vessel.
A suitable mounting ring can be provided by Kongsberg Maritime. A drawing is available for local manufacturing. End user manuals and source drawings (normally in AutoCad format) can be downloaded from our website.
Smooth surface is important
Make sure that the surface of the transducer face, as well as the plating and putty around the transducer is as even and smooth as possible.Obstructions on these surfaces will create problems with turbulent flow, and may cause noise.
Mounting screws or bolts must not be extruding from the transducer or the plating immediately around it.
NoteObstructions on these surfaces will create problems with turbulent flow, and may cause noise.
