SEINING MONITORING SYSTEM

Up to four sensors can be mounted on the footgear of the purse seine. These sensors transmit real-time data on the water temperature and the rate of descent. This data is received by an omnidirectional hydrophone on the vessel and then relayed as easy-to-read information to an onboard Graphical User Interface.

Seining system specifications include:

  • Omni-directional sensor providing Depth and Temperature information

  • Depth Reporting Range: 200, 500 and 1000 meters (200 m typical for seining)

  • Telemetry range: 1000 meters, omnidirectional

  • Telemetry Update rate: Standard report every three seconds; wirelessly programmable

  • Frequency: Nominal 28 kHz band, programmable channel frequency

  • Weight in air: 6 kg; Sensor max depth rating: 1000 meters

  • Temperature Range: -5 to 35 degrees Celsius

  • Temperature Accuracy: ±0.1 degree Celsius

  • Depth Accuracy: ± 1% Full Scale

  • Battery Life: Up to 10 days (depending on update rate)

eSonar’s affordable seine monitoring system with a towed hydrophone is portable from vessel to vessel.

 

The system comes with a full 12-month warranty.

SEINEVUE RECEIVER

Installed on the bridge, engine room or any other convenient location on the vessel, this marine grade technology receives data from the hydrophone and relays it to one or more displays via an Ethernet connection.

 

Overall Features

  • Latest receiver technology with enhanced performance

  • Handles data from individual and/or multi-data sensors

  • Fully software configurable via included EAD software

  • Broadcasts UDP Ethernet data to multiple devices your wired/Wi-Fi network

  • Power Requirements:

    • Powered by Power-Over-Ethernet (PoE) though the Ethernet cable

    • Cleaner installation with no separate power cords required

  • Water resistant enclosure for mounted in wheelhouse or below deck

 

Technical:

  • Rugged transformer isolated hydrophone inputs

  • 192kHz digitization rate with 24-bit signal sampling

  • Software adjustable gain for hydrophone flexibility

  • Ships with software selectable frequency band: 28kHz or 40kHz

  • (Other freq. available at time of order)

  • Typical maximum acoustic range of 2.5km

  • Multi-layer printed circuit board for improved signal to noise,

  • Water resistant design can be mounted close to hydrophone cable entry

  • ±12 Vdc phantom power available on hydrophone inputs to power preamps

  • Onboard gain sufficient to work without separate hydrophone pre-amps
