Dual frequency echo sounder transducer
Introduction
The Simrad 38/200 Combi W is a
dual frequency transducer (38 and 200
kHz), and both frequencies operate
with wide beams (31°). This makes
the transducer perfect for shallow
water sh detection using the 200 kHz
frequency, and excellent for bottom
discrimination from shallow depths
and down to several hundred meters
using both frequencies.
The transducer is not suited for
scientic use.

200 kHz
• Resonant frequency: 200 kHz
• Directivity: 16 dB
• Side lobes: Less than -20 dB
• Back radiation: Less than -30 dB
• Max. pulse input: 250 W
• Max. continuous input: 2,5 W
• Source level: 197 dB re 1µPa
• Transmitting response:
155 dB re 1µPa per V

Common
• Circular beamwidth: 31°
• Nominal impedance: 75 ohms
• Maximum transducer depth: 20 m
• Cable length: 15 m
• Cable diameter: 10.6 ±0.5 mm
Note: The transducer must be
submerged in water when transmitter
power is applied. Transmitting in
air will damage the transducer
permanently.
