The Simrad ES38-18/200-18C contains a 38 kHz split-beam transducer as well as a 200 kHz single beam transducer. Both offer 18 degrees beamwidth at their nominal operational frequencies. The split beam transducer is designed with three separate segments.

The transducer is streamlined, and designed to be mounted under the hull. Flush mounting is not recommended.

A fairing must be designed to fit between the top of the transducer surface and the hull. The fairing shall offer the necessary inclination angle, and provide space for the cable service loop. The fairing must cover the entire top surface of the transducer house. Supporting only at each end of the transducer may cause damage to the transducer if subjected to slamming.

The transducer housing is provided with two holes for mounting bolts. These shall penetrate the transducer fasten it to the fairing.

The transducer cable penetrates the hull using a stuffing tube and a cable gland.

Two different versions

The Simrad ES38-18/200-18C is available in two different versions.

• Open-ended cable
• Short cable with 8-pin male connector (MacArtney SubConn subsea connector (MCIL8M))

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