Transducer description
The rectangular sonar transducer allows the sonar beam to provide the swath coverage
of the water volume with electronic tilt.
The transducer is rather small. The transducer face
measures 184 x 184 mm, and the total weight (with
cables) is approximately 60 kg.
For installation, the transducer is mounted in a metal
mounting house, which is placed inside a blister. From
this blister, a watertight metal pipe must be designed to
reach well above the water line. The transducer cables
penetrate through the rear side of the mounting house,
and must be pulled through this pipe.
Note
The red protective coating is an vital part of the transducer. It is very important that
neither this coating nor the internal parts of the transducer are damaged during the
handling, installation or cleaning. Any holes and/or scratches in the transducer surface
will allow water to penetrate the transducer. If a leak occurs, the transducer must be
replaced.
A transducer must always be handled as a delicate item. Wrongful actions may damage
the transducer beyond repair.
Observe these transducer handling rules:
•
Do not
activate the transducer when it is out of the water.
•
Do not
lift the transducer by the cables.
•
Do not
step on the transducer cables.
•
Do not
damage the transducer cables, avoid sharp objects.
•
Do not
handle the transducer roughly, avoid impacts.
•
Do not
expose the transducer to direct sunlight or excessive heat.
•
Do not
use high pressure water, sand blasting, metal tools or strong solvents to clean
the transducer face.
•
Do not
damage the outer protective skin on the transducer.
