Innomar Technologie GmbH (2023-01) 179
Transducer
Dimensions (D×H) 470 mm x 55 (145) mm
Weight in air / water c. 32 kg / c. 24 kg
Material / Depth Rating SS 1.4571 (316Ti) / 200 bar (2,000 m)
The transducer is used for transmitting and receiving.
The transducer cable is plugged on both ends, the standard cable length
is 5 meters.
Transducer mounting is via 12 bolts M8.
Make sure the correct orientation (arrow
pointing forward) for correct beam-
steering. With the orientation shown on
the left (arrow and connector box pointing
forward), the system will correct for pitch
and not for roll.
For acoustic isolation there are rubber
tubes and rubber washers provided,
which have to be put on the bolts as
shown in the picture:
Important notes for system handling and installation
The subsea unit needs to be laced firmly onto a rigid support structure of the ROV.
Install and transport the pressure pod with the “water sensor” pointing upwards
(see arrow in picture above).
All connectors have to be protected by pressure caps or dust caps during installation,
transport and storage.
Before diving, make sure all plugs are connected tightly and all unused connectors are
protected by dummy plugs (BURTON pressure caps turned out not to be sufficient).
The cable’s connectors have to be protected by dust caps if not used.
Never plug and unplug connectors when power is switched on.
During transport and storage, the provided transport cases have to be used.
The “water sensor” disables the transmitters if the pressure pod is not below water level.
This shall prevent running the system in air, which would destroy the transducer and harm
the electronics due to insufficient heat transfer.
