5.3 Installation of Transducer
The standard installation of the transducer is shown in figure 5.5.
Figure 5.5 Installation of Transducer
In case of Inner-hull
Using the optional Inner-hull kit (MFB-04), install the transducer to the inner side of ship’s bottom.
Caution on installation
(1) Select the location where no bubble is
generated during navigation.
(2) Select the relatively thin location of ship’s
bottom.
(3) Be sure to remove oil on the contact
surface. File the contact surface with sand
paper (#400) so that the adhesive strength will
increase.
(4) The adhered surface will dry in about two
hours.
(5) Leave the unit for a whole day and fill in
the coolant. More than 80% of the transducer
should be submerged in the coolant.
Caution: It is strongly recommended to confirm the location of the installation of Inner-hull
with the ship manufacturer. The Inner-hull device is more simplified method. The gain falls
dramatically in comparison with the Through-hull performance. Low frequency (50 kHz)
may not be used due to large signal attenuation in some cases. Depth range performance
using 200 kHz Transducer in case of Inner-hull can be less about 50% than that of
Through-hull.
