Marine Electronics Ltd. products

The Dolphin SeaView is a highly advanced high-frequency imaging sonar designed by Marine Electronics Ltd., particularly for use with small remotely operated vehicles (ROVs). It stands out due to its compact design, allowing integration with minimal spatial requirements. The sonar operates at a frequency of 720kHz and provides real-time continuous scanning across a 120-degree sector at up to 30 frames per second. With 192 beams originating from a composite array, the device promises precise and detailed imaging. It supports both Ethernet and VDSL interfaces with a power consumption of less than 15W, making it highly efficient for extended operations. The integrated tilt sensor optimizes performance for various underwater orientations. Standard depth rating reaches up to 500 meters, with an optional version equipped for 3000 meters for deeper oceanographic explorations. It is compatible with Windows operating systems, facilitating user-friendly operations and data management.

The Dolphin 6201 Obstacle Avoidance Sonar is engineered specifically for Autonomous Underwater Vehicle (AUV) and Remotely Operated Vehicle (ROV) navigation. It offers versatile connection options with control via Ethernet for AUVs and either Ethernet or VDSL for ROVs. This sonar system is equipped with real-time continuous scanning capabilities over a 120-degree sector, with selectable options for 90 or 60 degrees. Its acoustic range extends up to 200 meters, enabling it to track up to 250 targets simultaneously. The sonar supports depth ratings of 4000m or 6000m as an option, making it suitable for various underwater applications. The system's imaging and tracking software, operable on Windows, generates images and navigational messages to prevent collisions within a configurable avoidance corridor, enhancing the safety of underwater operations.

The Model 2512 Pipe Profiling Sonar provides an efficient acoustic solution for profiling the interiors of liquid-filled pipes or boreholes without the need to drain them, unlike traditional camera surveys. The system includes an underwater Scanning Unit, which may be mounted in various configurations such as skid, float, tractor, or ROV, and a compact Ethernet Interface Unit. This setup requires a Windows PC with an Ethernet port to operate the 2512E system software. The Scanning Unit is robustly constructed with a stainless steel body and a pressure-balanced Peek transducer housing, capable of operating at depths up to 100 meters. For portability, it can be powered by two lead-acid batteries along with a notebook PC. The system features internal Pitch and Roll sensors to display its orientation in the pipe. The Ethernet Interface Unit connects to the host PC, supporting cable payout encoders for precise distance measurement. It operates on AC power, providing electrical isolation from the underwater system. Capable of real-time 360-degree scanning, it offers quick, high-resolution image capture and seamless integration with third-party 3D modeling software.

The Multi-Return Altimeter 11001 from Marine Electronics is engineered to meet the demanding sonar data acquisition needs of oceanographic and scientific research. Unlike conventional 'first-return' altimeters, this model digitizes receiver output at high speed into a FIFO memory. This digital processing is facilitated by an onboard RISC microcontroller, allowing precise range calculations to the seabed. The device is set up via an RS232 connection to a PC, with parameters stored in FLASH memory, ensuring no power is needed post-configuration. Outputs include both analog and digital, with the analog output managed by a 12-bit converter adjustable for 5v or 10v full-scale. The device also supports high-resolution digital data output through RS232 and RS485. It operates with programmable start and stop ranges for true zoom capabilities and can process up to 4095 samples at a 1-second sampling rate. The Altimeter's comprehensive functionality extends to real-time imaging and seabed detection using advanced DSP techniques.
