TRANSDUCER INSTALLATION MANUAL

1 INTRODUCTION

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. Finite measurements and fabrication should be based on the physical transducer to allow for manufacturing tolerances.

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.

TRANSDUCER INSTALLATION MANUAL

4 GENERAL CONSIDERATIONS

The transducer is mounted on the hull below the water line, normally using a permanent sea chest. The transducer must be mounted so that it is aligned with the fore-aft axis of the vessel. It must also be mounted so that the flat underside of the transducer is as close to horizontal as possible.

If the vessel has a keel, the transducer can be mounted somewhere along the length of it. If it is mounted on the hull, it should be far enough away from the keel so that the keel will not be detected within the 120° beam angle. Figure 6 on page 8 shows a sea chest type through-hull mounting designed specifically for a fast moving, alloy hull crayfish boat.

The performance of the system is directly related to the mounting location of the transducer, especially for high-speed cruising. The installation should be planned in advance, keeping in mind the fixed cable length of your transducer (5m / 10m / 20m) and the following factors:

»

Air bubbles and turbulence caused by movement of the vessel seriously degrade the sounding capability of the transducer. The transducer should be located in a position with the smoothest water flow.

»

The transducer should not be mounted close to propellers because noise from propellers can adversely affect the performance of the transducer.

»

Mount the transducer inboard of lifting strakes as these create acoustic noise.

»

The transducer must always remain submerged, even when the boat is rolling, pitching or planing at high speed.

»

A practical choice would be somewhere between a 1/3 and a 1/2 of the boat’s length from the stern. For planing hulls, a practical location is generally towards the rear of the vessel, to ensure that the transducer is always submerged, regardless of the planing angle.

»

Do not mount another transducer near the WASSP transducer as it will interfere with the 120° beam.

Planing hulls

On planing hulls the transducer obviously needs to be mounted in or on the aft part of the hull, which stays in the water when the vessel is on the plane.

The transducer can be mounted either in a streamlined housing or blister on the hull or inside the hull in a specially prepared cofferdam, with the transducer face flush with the hull and faired to the hull shape.

It is important that the part of the hull in front of the transducer is smooth and has no hull penetrations or attachments of any kind.

Displacement hulls

A practical choice is somewhere in the area between a 1/3 and a 1/2 of the vessel’s length, from the bow. The transducer should be mounted in a housing or blister attached to the hull.

The disturbed aerated water tends to be in a layer against the hull, it’s thickness varies by

Page 10 of 24

wassp.com

Doc: Transducer Installation

Version: 1.0 April 2016

TRANSDUCER INSTALLATION MANUAL vessel’s speed and sea conditions. Therefore the deeper the housing is, i.e. the further the transducer is away from the hull, the better the equipment will perform. Also on

V-shaped hulls the housing should be mounted against or close to the keel, again to get deeper and away from aeration and turbulence. The 120 degree athwart ship pattern must be kept in mind when mounting the transducer. No part of the keel or hull should protrude into this pattern.

Larger displacement hulls with bow thruster

The best location on these vessels is in or against the keel, forward of a line just aft of the thruster cavity. Locations further aft are becoming heavily affected by aeration when the vessel pitches and air exhausts out of the thruster tunnel on the downward movement of the bow. This air creates havoc with the performance of any transducers further aft on

the hull. “Figure 6. Transducer mounting locations for larger displacement hulls” suggest

mounting locations for these types of vessels.

In these installations, the strength of the mounting becomes very important, as the transducer can be out of the water when the vessel pitches. Re-entry into the water exerts large forces on the transducer face and the mounting structure.

See “6.1. 160kHz Transducer Mounting” on page 16 and “6.2. 80kHz Transducer

Mounting Assembly” on page 18 for mounting diagrams and instructions. These steps

must be carried out accurately and completely.

5.2. MOUNTING THE CABLE GLAND

See “Figure 8. Mounting the Gland Assembly” on page 13 and “Figure 9. Gland

Assembly - Cable Connectors” on page 14.

In the external sea chest and fairing type installations, the cable gland forms a seal where the transducer cable passes through the hull. In low profile sea chest installations, the gland passes through the sea chest cover.

The gland pipe and a single gasket are the only parts of the gland that are located inside the sea chest or outside the hull, all other parts are attached to the gland pipe inside the vessel.

Gland Mounting Instructions

Depending on the type of installation, there are various ways of mounting the cable gland to the hull. The following example describes how to mount the gland through the hull and then feed the cable through the gland. Adapt the following procedure to suit your installation while taking the following into consideration:

»

Always use a good quality marine sealant to seal across areas that can leak.

»

When installing the gland packing ring, apply soapy water to the inside of the packing ring and pass it over the transducer cable until it is sitting on top of the gland pipe.

The soapy water allows the packing ring to slide easily down the cable. When sitting on top of the gland pipe, clean as much of the soapy water off as possible to ensure the packing ring grips the cable when pressure is applied by the gland nut.

»

Tighten the gland nut by hand until secure. With the vessel in the water, check for leaks at the gland and if leaking slightly, tighten the gland nut with a spanner until the leak stops.

Place the bottom gasket over the gland pipe and apply marine sealant to both sides of the gasket. See Figure 11 below.

Push the gland pipe into the hole.

Place the top gasket over the gland pipe and apply marine sealant to both sides of the gasket.

Place the plate over the gland pipe and onto the top gasket.

Screw the lock plate onto the gland pipe until a good joint is achieved.

Clean away any excess marine sealant.

Feed the transducer cable through the gland. See “Figure 12. Gland

Assembly - Cable Connectors” on page 14 for a set of steps to feed a

RJ-45 type cable through the gland pipe.

Screw the gland lock nut as far as it can go onto the gland pipe.

Place the gland packing ring over the cable until it sits on top of the gland pipe.

Place the steel washer and gland nut over the cable and screw the nut onto the gland pipe firmly by hand.

With the vessel in the water, check for leaks at the gland and if leaking slightly, tighten the gland nut with a spanner until the leak stops.

With all leaks stopped and while holding the gland nut with a spanner, tighten the gland lock nut against the gland nut with a spanner.

5.3. CABLE INSTALLATION

The transducer cable consists of seven CAT-5 cables and one screened pair for the transmit connection.

To fit the RJ-45 connectors and cable through the gland, no special preparation is required.

The WASSP transceiver cable end has the RJ-45 connectors fitted with “staggered” cable lengths. This allows each RJ-45 connector and its associated cable to be fed through the gland fitting easily.

Commencing with the black RJ-45 cable and black transmit cable, feed each cable in turn through the gland, finishing off with the grey RJ-45 connector and cable.

Complete fitting and tightening the gland as shown in “Figure

8. Mounting the Gland Assembly” on page 13.

NOTE: Colour code for transmit cable conductors: White, Black and Green.

CAUTION: DO NOT STRAIN THE TRANSDUCER

CABLE!

Forcing the cable to bend, twist, or stretch beyond its means will damage the transducer and impair performance.

Once the transducer has been installed, ensure that the transducer cable is not under tension.

Use cable ties (or similar) to secure the cable as necessary.
