Simrad ES333-7CDK

The Simrad ES333-7CDK is a compact single- or split-beam transducer. The transducer is mainly designed for underwater science applications.

This transducer is available in two different versions:

  • ES333-7CDK Single: Single beam version
  • ES333-7CDK Split: Split-beam version

Both versions are rated for maximum 1500 meters depth. They are designed to be deployed on submerged platforms for underwater science applications.

The split-beam version offers three individual sectors. 

The beamwidth is 7 degrees at its nominal operational frequency.

The compact size and weight of the ES333-7CDK allows it to be mounted on a large variety of subsea platforms. The transducer is provided with two meters cable, and the cable is terminated with an eight-pin male connector that fits directly into our range of subsea transceivers.

The transducer is thus especially well suited for use with autonomous and subsea products such as the WBAT (Wide Band Autonomous Transceiver), WBT Mini and WBT Tube.
