1.4 Transducer Unit
The performance of this equipment is directly dependent on the installation of the transducer.
The installation of the transducer and the tank should be accomplished by a dockyard referring
to the installation drawings at the later part of this manual.
1. 4.1 Mounting Location
To decide the location of the transducer, the following points should be taken into account.
•
Locate the transducer of DS-80 at least 2.5 m from the transducer of an echo sounder.
STERN
BOW
2500 mm or more

•
Separate as far as possible from air bubble sources; e.g., side thruster and water disposal
pipes.
•
Install in close proximity to the keel, for uniform water flow.
•
Generally, best performance is obtained by mounting on the bow; the stern side is
influenced more easily by air bubbles and propeller caviation.
•
Never apply ordinary paint to the transducer face. Whenever the ship is dry docked, the
transducer face should be cleaned off oysters and foreign materrial.
