EA640

Single beam echo sounder

The EA640 Wideband hydrographic echo sounder is suitable to all ocean depths, offering applications from extreme shallow to full ocean depths. It is designed for high performance hydrographic single beam echo sounder depths, deployable in all water conditions, from very shallow to full ocean depths. The EA640 is capable of operating from 12 kHz to 500 kHz using the WBT wideband transceiver unit, enabling it to function simultaneously with various transducers.

Advanced Echo Sounder Capabilities

For hydrographic tasks in full ocean depths, the high-performance EA640 presents an advanced echo sounder that operates with an extensive frequency range from 12 kHz to 500 kHz. It accommodates high-power output from 10 kHz to 50 kHz for deep-water explorations. With a wide array of transducer interfaces compatible with both Kongsberg transducers and third-party options, the EA640 offers incredible versatility. Its world-class bottom detection algorithms deliver reliable, high-precision depth determination, complemented with valuable bottom slope information.

The EA640 Wide Band Transceiver - WBT

The EA640 features a standard 4-channel WBT that transmits and receives data across a frequency range of 10 kHz to 500 kHz, simultaneously. Each channel is configurable for various applications or redundancy with a standard transmit power of 500W per channel. High-power WBT options provide 2 channels from 10 to 50 kHz with up to 2000W transmit power. Communication with the EA640 software is made possible through an ethernet link to a Windows 10 computer, with support for multiple configurations of WBTs. License management and power supplied by a 12-15 VDC source underscore this versatile transceiver's capabilities.

Enhanced Data Interpretation and Display

The EA640 software, an intuitive and user-friendly interface, allows operation from a Hydrographic Operation Station (HOS) or any Windows 10 compatible PC. Users can personalize their display settings, choose between various screen presentations, and save settings for different operations. The EA640 ensures internal storage of all raw sample data, including external input sensor data for replay purposes. Additionally, the map view offers a comprehensive geographical display of the vessel's position, tracks, and sidescan coverage based on user-supplied WMS or GeoTIFF services.
