Image Profiling Sonar 1640 / 2640 Specification

Marine Electronics Model 1640 Imaging Sonar

The Model 1640 Sonar provides high resolution sonar images in a transportable PC format for the minimum cost.Typical applications include ROV navigation, sea and riverbed imaging, debris clearance, target location and tracking.The standard Model 1640 operates at 500kHz with a 2.5 horizontal beamwidth and a 20 vertical beamwidth. Alternative transducers may be fitted to give different beam patterns and the acoustic frequency re-tuned in the range 100kHz to 2MHz. This flexibility allows Marine Electronics to provide custom solutions to solve specific problems foran "off-the shelf" price.

Marine Electronics Model 2640 Profiling Sonar

The Model 2640 Profiling Sonar effectively operates as a "first return" scanning echo-sounder. The standard unit operates at 700kHz with a 2.5 conical beam to give precise range and bearing information over the scanned area. Typical applications are dredging and trenching operations, river and sea bed profiling and pipe laying. Multiple 2640 units may be connected together to cover either a larger area or for trenching a before and after comparison may be displayed simultaneously. As with the Model 1640 Imaging Sonar alternative transducers may be fitted to customise the beam pattern.
