Simrad ES333-7C

Outstanding among its key features, the Simrad ES333-7C is a wide-band split-beam transducer optimized for fishery and research applications. The transducer operates with a nominal frequency of 333 kHz within a frequency range of 280-450kHz. A notable characteristic is the narrow beamwidth of merely 7 degrees, alongside the maximum input power rated at 200 W. It has precise physical dimensions with a diameter of 120 mm and a height of 75 mm. The Simrad ES333-7C comes with mounting hardware and essential documentation, ensuring ease of installation either flush with the hull plating or the bottom of a blister, as well as the possibility of being mounted at the bottom of a drop keel.

The Simrad ES333-7C excels in its performance specifications with a nominal frequency of 333 kHz and a frequency range of 280-450 kHz. Its sophisticated design enables it to achieve a beamwidth of 7°, with a figure of merit standing at -11 dB and extraordinary max source and sensitivity levels. Furthermore, it is built to operate effectively with a maximum input power of 200 W and a max pulse length of 16 ms, capable of handling a max duty cycle of 1%. The weight and outline dimensions are meticulously detailed providing specifications for operations in different conditions, including a depth rating of 20 meters and operating temperature windows specified for optimal performance.

To ensure the longevity and precision of the Simrad ES333-7C transducer, specific rules for handling must be observed. It must be treated with care, protected from impacts, direct sunlight, excessive heat, and rough handling that could compromise its integrity. Cleaning methods are prescribed to avoid damage, with particular mention to avoiding high-pressure water and strong solvents. The installation principle details the process involving a steel blister, mounting and clamping rings, and proper indication of the transducer's forward direction. The connections for sectors and digital output emphasize careful attention to detail for the flawless operation of this complex piece of marine technology.
