Installation of the transducers
Proper installation of the transducers is crucial for the effectiveness of the system.
The transducers need to be placed at 1/3 and 2/3 of the length of the hull.
Identify a suitable location for the transducers:
•
Direct to the inside the hull (not on insulation or other material)
•
Spot with min. diameter of 75 mm
•
Even surface
1. Use a sanding machine to remove all paint and make the spot as smooth/even as possible
2. Clean the spot and the vibrating membrane of the transducer thoroughly with acetone or a similar cleaning product. Do
not touch these surfaces after cleaning. If you accidentally did, clean again!
3.
Apply the glue generously on the transducer membrane, making sure that the entire surface is evenly covered. The film of
glue should be sufficiently thick to absorb all possible unevenness of the spot you have prepared for the transducer. You
do not need to cover the threaded hole in the transducer membrane. Make sure that no air bubbles can develop between
the membrane of the transducer and the surface on which it is glued
4. Place the transducer on the surface immediately after applying the glue (the glue hardens very quickly)
5. Press the transducer slightly, making sure the glue has completely spread out, filling all possible air gaps and absorbing any
unevenness of the steel on which the transducer is glued. You should see a little glue coming out from under the
transducer all around
6. Do not remove the glue that came out from under the transducer surface. The Loctite 3090 hardens in 2 minutes. However,
for the glue to completely cure allow 24 hours. Hence,
wait 24 hours before activating the transducer
7. If the transducer is installed in a location where it can be exposed to seawater, lubricants or cooling liquid, you can protect
the glue with a marine kit. We recommend TEC 7. After installing the transducer, apply a seam of kit all around the juncture
of the transducer, sealing off contact between the glue surface and any liquids.
