Transducers
Shipsonic offers 3 different types of transducer:
80 Watt 23 kHz, IP67 or IP68
This transducer is exeptionally small given its power and response frequency. That makes this model especially apt for installation on box-coolers, where installation space is often confined.
100 Watt 28 kHz, IP67 or IP68
The 100Watt, 28kHz is our most used model. Very apt for installation on piping.
120 Watt 20 kHz, IP67 or IP68
A heavy hitter, 120 Watt! Very good for application on thick walls of sea-chests and hulls.
Transducers are directly glued on the object, optimizing energy transfer. All models can also be used with an aluminium installation adaptor. The adaptor can be machined in the same curve as e.g. piping or a bucket strainer on which the transducer is to be installed.
Recommended glues
Glue used to install the transducers should harden completely, like glass. Glues that maintain some elasticity, are not suited. The elasticity dampens the ultrasonic vibration.
For gluing the transducer in normal circumstances we recommend Loctite 3090.
For protecting the glue-seem against liquids (cooling liquid, oil that might slosh around) we recommend you apply Tec7 around the seam after installation of the transducer.
If an IP68 transducer is needed, e.g. for installation in a ballast tank, we recommend Loctite 9466.
For protecting the glue-seem against liquids (cooling liquid, oil that might slosh around) we recommend you apply Tec7 around the seam after installation of the transducer.
Loctite 518 can be used between the surfaces of the transducer and the adaptor.
Installation
Installing the control unit and powering it up is very straightforward.
The critical issue is determining the correct transducer locations. This is an acoustical problem, and acoustical problems are notoriously complex.
To address it, Shipsonic has developed a Digital Signal Processor (Shipsonic DSP, patent pending) coupled to either a magnetic ultrasonic microphone or an ultrasonic hydrophone. We combine this with removable test transducers which allows us to do in-situ analysis of ultrasonic sound pressure to optimize the design of your system.
Our most important agents have such a set consisting of
-
a Digital Signal Processor
-
a magnetic ultrasonic microphone
-
an ultrasonic hydrophone
-
a set of removable test transducers
