Robust Design and Installation

The ES120-7C transducer has been designed to withstand a large water pressure, making it well suited for use with towed bodies or autonomous vehicles. The recommended installation method is through the hull plating using mounting and clamping rings provided. For flexibility, the transducer can also be mounted using brackets and M8 screws at the back.

Key Features and Performance

Key features of the Simrad ES120-7CD include a wide-band split-beam—targeted at fishery and fishery research applications—and a resonant frequency of 120 kHz. Its depth rating reaches down to 1500 m, and the beamwidth is 7° which is optimal for targeted signal direction. The ability to operate with a maximum input power of 500 W allows for strong signal transmission and reception in underwater environments.

Handling and Durability

To ensure the longevity and optimal performance of the Simrad ES120-7CD, it's crucial to handle the transducer correctly. Important handling rules include not activating the transducer out of water, avoiding rough handling and impacts, not exposing it to direct sunlight or excessive heat, and avoiding the use of metal tools or strong solvents on the transducer face. Following these guidelines will help maintain the integrity and functionality of the transducer.
