Chapter 4 Hardware installation
4.1, Transducer installation
The location of the transducer is very important for maintaining reliable bottom tracking
performance of the equipment. Avoid installing transducers in locations where the transducer
will be subjected to turbulent water, air bubbles, or vibration. It is preferable to mount the
transducer on the side of the hull where the propeller blades are normally moving downwards.
The upward motion of the propeller can generate pressure waves, which push air bubbles up
against the hull. By mounting the transducer on the downward side, the hull will tend to protect
the transducer from this effect. The transducer should be mounted on, or adjacent to, the ship’s
centerline. Wherever practical, the transducer face should be parallel to the waterline. In
addition, there should be sufficient room to permit use of the necessary tools to facilitate the
installation-mounting requirements.
Fig.4-1 Transducer installation
To fix the transducer, the best location is in the middle side of the hull, thus reducing the influence
and interference of the traffic surge to the transducer. When the speed of the ship is fast, then the
juction pole connected with the transducer must be tilted slightly backwards, which is carried
