Simrad ES38-10
SPLIT-BEAM TRANSDUCER
The Simrad ES38-10 is a split-beam transducer of medium size, designed
for fishery and fishery research applications. The beamwidth is 10 degrees
at a operational frequency of 38 kHz. The transducer is designed with
three separate sectors and for transducers manufactured later than 2021 it
also includes a sensor to measure sea temperature.
The transducer is normally mounted flush with the hull plating or the
bottom of a blister. It is provided with an installation flange, and by means
of a clamping ring, it is secured to a mounting ring welded into the hull
plating or the bottom of a blister. The clamping ring is provided with the
transducer and already fitted.
The transducer can also be flush mounted at the bottom of a drop keel.
The transducer cable penetrates the hull using a stuffing tube and a cable
gland.

Rules for transducer
handling
To secure the long life and accu-
rate results, the transducer must
be handled correctly.
A transducer must always be
handled as a delicate item.
Wrongful actions may damage
the transducer beyond repair.
Observe these transducer
handling rules:
• Do not activate the transducer
when it is out of the water.
• Do not handle the transducer
roughly, avoid impacts.
• Do not expose the transducer to
direct sunlight or excessive heat.
• Do not use high-pressure water,
sandblasting, metal tools, or
strong solvents to clean the
transducer face.
• Do not damage the outer protec-
tive skin on the transducer face.
• Do not lift the transducer by the
cable.
• Do not step on the transducer
cable.
• Do not damage the transducer
cable, avoid sharp objects.

Connections to a SubConn socket
The transducer connects to terminals 1 through 8 on a circular 8-pin SubConn socket. This
socket is used for the General Purpose Transceiver (GPT), and for some versions of the Wide
Band Transceiver (WBT)
