Gradiometer Controller
from Geomatrix

The G-882 Gradiometer Controller was designed by Geomatrix Earth Science Ltd to specifically manage power distribution and data for an array of Geometrics G-882 marine magnetometers deployed on a gradiometer frame. This power and data solution permits a array of G-882 magnetometers to be deployed off a soft tow cable… no wire line or telemetry system required… and is perfect for shallow water small deployments.

Features

• Automatic Power and data management.
• Controls up to 4 G882 marine magnetometers and one serial device.
• Regulated 28V DC output at wet end.
• Rack mountable.
• Typically supplied with 150m soft tow cable and 20m deck lead.
• High load soft tow cable with rugged polyethylene outer jacket, boasts a breaking strain of 2000kg.
• Custom frame cabling.
• No wet end electronics required.
• Simplifies system diagnostics and trouble shooting.
• Supplied in rugged transit case.

The distribution unit supports 3 data channels. By concatenating 2 G-882 magnetometers, and passing the data as a single sentence, the Gradiometer controller is capable of supporting 4 G-882 magnetometers and one other serial device. The third data channel offers the user the ability to record a frame mounted altimeter, gyro or responder. Power is automatically regulated by the specialised electronics ensuring a constant 28V DC is supplied to all devices.

The front panel LEDs indicate when data is being received by the G-882 magnetometers and the serial device, simplifying system fault diagnostics.
