Transducer
The performance of the color sounder depends upon the transducer position.
• A place least affected by air bubbles should be selected since turbulence blocks the
sounding path.
• Select a place not influenced by engine noise.
• Further, select a place not influenced by other electronic device.
Install the transducer on the hull, orienting it so the bow mark is facing the ship's bow.
Note: Carefully handle the transducer. Do not lift the transducer by holding the cable, nor
drop it.
It is known that air bubbles are fewest at the place where the bow first falls and the next
wave rises, at usual cruising speed. In small, slow-speed boats, the position between 1/3
and 1/2 of the ship's length from the bow is usually a good place. The face of the transducer
must be facing the sea bottom in normal cruising trim of the boat.
Refer to the installation drawing for the transducer, combined with the thru-hull pipe
TFB-1600 and optional transducer tank T-625.
About transducer casing
The FURUNO transducer tank is finished with lacquer primer to prevent corrosion in
storage. After welding the casing to ship's hull, remove the lacquer primer, using lacquer
thinner. Coat casing with same paint as used on ship's hull.
How to remove lacquer primer from the tank (Several methods)
1.
Dissolve and remove paint with solvent.
2.
Remove rust, coating, oil film, etc, with a blaster.
3.
Remove with a disk sander or foil brush
Transducer Fixing Plate Kit (optional) assembly
When using the optional T-625 transducer tank, you can use the optional T-625-A
transducer fixing plate kit against expected noise of the ship movement.
