Hull-Mount Transducer (Mounting Frame)
Dimensions (L×W×H) 39 cm × 38 cm × 10 cm
Additional Frame Weight c. 10 kg
The pole-mount transducer (see previous page) is delivered without
the fairings and mounted into a shock-absorbing frame to reduce
structure-borne noise. This is suitable for mounting the transducer
directly to the vessel’s hull (sea chest), into blisters or gondolas.
For drilling the mounting threads into the flange at the correct positions,
INNOMAR provides a drilling template.
Please note that the M8 mounting studs on the transducer have to be
longer (54 mm) for the frame-mount than shown on the prev. page.
Transducers for the INNOMAR “compact”, “light” and “standard” models have the same
dimensions, but differ in electrical connections. Make sure to use the correct transducer and
check the serial number!
For the “standard” transducer the correct orientation (arrow pointing forward to the vessel’s bow)
is important for correct beam stabilisation!
To avoid biofouling reducing the system performance, hull-mounted transducers have to be
coated using an INNOMAR approved anti-fouling paint. Please do not use any other paint since
this might destroy the transducer. We also recommend anti-fouling if a pole-mounted transducer
is operated in tropical waters for a longer period. See section 8.1.3 on page 117 for details.
The frame is mounted via
six bolts M8. The other
two larger holes in the
frame are left open to
ensure water filling of the
sea chest.
