5. Transducer
5.1 Transducer Type
The WASSP system uses a transducer intended to be either pole mounted or flush mounted
inside the hull through a suitable opening to allow the bottom face of the transducer to be in
contact with the sea water.
The transducer is a rectangular-shaped, low-profile transducer for through-hull mounting,
encased in a sealed sea chest made to suit the vessel’s hull dead rise angle. The transducer is
best suited to steel and aluminium hulls.
A sea chest for housing and sealing the transducer should be designed and constructed by a
reputable shipyard to suit the size and contours of the hull of each individual vessel. This must
be sized and constructed accurately.
The sea chest provides a stable platform for the transducer and must be mounted as horizontal
to the vessel’s waterline as possible. An optional gland supplied by WASSP Ltd. in alloy, plastic,
or steel, provides the transducer cable through-hull seal.
The transducer is supplied standard with a 10m cable. Different cable lengths are available.
Please ask your WASSP representative for details.
