ES18-11MK2
18 kHz wideband transducer with 11 degrees beamwidth
The new ES18-11MK2 transducer has an extended operating range compared to the existing ES18, increasing the data resolution and providing more information for target identification. Additionally, with the new design of the transducer elements, the challenge of ringing is reduced, which means the transducer can be used for both shallow and deep water measurements.
Transducer features
The ES18-11MK2 transducer is a split-beam transducer featuring large bandwidth. The transducer is designed having four sectors allowing for tracking of object.
Typical installations
The transducer is mainly designed for use on vessels and larger Unmanned Surface Vessels (USVs). The recommended installation is in a drop keel or a blister below the bubble-flow along the hull.
Example of ES18-11MK2 data improvement before (left) and after (right) that the ringing had been reduced. The improvement allows for collecting usable data at shallow depths.
