- What are the benefits of the eSonar Trawlvue System?
The eSonar Trawlvue System offers many new features that go above and beyond that of their competitors. Several of these features include:
- All sensors are wirelessly programmable
- Average battery life of up to 3 weeks for the basic sensor
- Made of a lightweight Delrin polymer
- Compatible with the Netmind Trawl Monitoring System receivers
- Multi-function sensors (user configurable)
- Competitive Pricing
- The eSonar Trawlvue System offers many new features that go above and beyond that of their competitors. Several of these features include:
- Does the temperature affect battery Life?
- No, the temperature (both water and in air) will not affect the life of a sensor's battery.
- Can we check the voltage charge remaining on sensors?
- Yes. In order to check the voltage on your sensor, simply place the leads of a voltmeter between the "S" and "-" bolt heads on the sensor's end cap.
- How do we check if the sensors are operational?
- To check if the sensor is operational, place a jumper cable between the "S" and "-" bolt heads on the sensor's end cap. This will activate the sensor causing it to transmit a signal. Typically you can hear the main transmit as a "click" sound coming from the sensor. Also, the sensor can be placed in front of the hydrophone that is connected to the receiver and the update will be displayed on the computer display software.
- How do we ensure sensor orientation?
- For all sensors, the transducer end of the sensor must be pointing to the ship. In the case of the spread pair, the holes in the side of the sensors housings must be pointing at each other. And finally, for the Headline sensor, the hole in the side of the sensor must be pointing towards the bottom/footrope.
- How do we charge sensor Batteries? How long does it take??
- To charge your sensor's battery, plug the provided eSonar Charger Plug into the end cap of the sensor (after ensuring that the charger is plugged in). Please note that the Charger Plug can only plug onto the sensor in one orientation. Charging is completed when the LED turns from Red to Green, and should take between 1.5-2 hours.
- How frequently should sensors be charged?
- Sensors should typically be charged either after one long trip, or two short trips. (Tip: To maximize the life of your batteries, attempt to charge them only when the sensor can no longer communicate with the receiver).
- What is your sensors battery life?
- The battery in the basic sensor should last up to 3 weeks between charging.
- Is information displayed in real time?
- Yes, all data from all sensors is displayed in real time. As an added feature, the data can also be stored inside the sensor for future processing.
- How do you perform a system test?
- A system test can be performed by connecting the Display computer and the hydrophones to the Receiver. Turn on the receiver and run the display software. The system is now ready to test the sensors. This can be performed in air (with a towed hydrophone configuration) or in the harbor when hull mounted hydrophones are installed. For the in-air test, the sensors should be activated by placing a jumper between the "s" and "-" bolts in the sensor endcap. This will cause the sensors to update, thereby displaying data in the display software. For in-water testing, simply lower the sensors into the water so they have a line of sight with the hydrophone. Again, the sensors will provide updates that can be seen on the display software. NOTE: The data displayed may not be correct due to a variety of reasons, however, it will confirm that the system is properly connected.
- What are the sensor specifications?
- For all sensor specifications, please go to the Product Section of the website.
- What are minimum computer requirements?
- Computers must be Windows XP or higher.
- How are sensors configured?
- The sensors are all configured with default settings from the factory. These settings can be changed at any time by the user by connecting to the sensor wirelessly using the eSonar configuration software which can be downloaded free from the eSonar website. Depending on the individual user's requirements, functionality of any sensor can be changed as the need arises.
- What is the maximum depth for the sensors?
- The maximum depth to which your sensors can safely perform is 1200m. Beyond this depth an alternate pressure housing is required.
