Transducer types

Shipsonic™ has different transducer models (water resistant and waterproof) with different mounting methods (eg on curved surfaces such as piping) and different Wattages.

Optimized transducer housing

We intentionally chose a PVC housing, while this is not common in shipping. However, metal housings have too much mass compared to the mass of the transducer itself. These housings, therefore, absorb more energy, sometimes resulting in the housing cracking up. The mass of the metal housing also affects the resonant frequency of the transducer. The PVC housing of the transducer is not a way of cost-saving, but a conscious technical design choice. Within the PVC housing, the resonance element of the transducer can vibrate completely independent. With the water resistant model, the contact surface of the transducer is glued directly to the object to be protected, so no intermediate steel or artificial part of the housing gets in the way.


All Shipsonic transducer models can be obtained as either:

  • 100 Watt 28 kHz (PVC housing, water resistant, direct glue)
  • 100 Watt 28 kHz (stainless steel & POM housing, waterproof, direct glue)
  • 120 Watt 20 kHz (POM housing, waterproof, direct glue)
  •   50 Watt 40 kHz (stainless steel & POM housing, waterproof, direct glue)

Standard model

Our standard model is water resistant, with a PVC housing. It is directly glued to the object to be protected.




Installation with adapter

Standard model PVC transducer can also be installed using an adapter. This adapter can be customized and made-to-fit. For example, when installing on curved surfaces (bucket strainers, piping)

Waterproof with POM housing and stainless steel foot

Often, there is water standing in between ballast and/or fuel tanks. Then our waterproof model is needed. It is directly glued, so use a waterproof glue or protect the glue with a kit.



Waterproof, POM housing, stainless steel foot, and installation bracket

For installation in the sea chest, directly under the tube bundle, or in any tank (ballast, diesel) to prevent algae growth in the tank.
