Oculus M-Series
Single and dual-frequency multibeam imaging sonars (375kHz–3.0MHz) in a 500m-rated aluminium housing for ROV inspection and navigation.
Description
The Oculus M-Series is a range of single and dual-frequency multibeam imaging sonars in a compact, rugged anodised aluminium housing depth rated to 500m. It is designed for use on small inspection-class ROVs through to larger work-class platforms.
Key features
- Frequencies from 375kHz to 3.0MHz, model dependent
- Operating ranges from 0.1m up to 200m
- 130° horizontal and 20° vertical apertures, up to 512 beams
- Range resolution down to 2mm and update rates up to 40Hz
- Integrated water pressure and temperature sensors for velocity-of-sound calculation
- 100-BaseT Ethernet, with a 2-wire DSL extender option
Applications
Inspection and navigation on ROVs from small inspection-class to work-class platforms. Models: M370s/MT370s/MD370s (375kHz single frequency, 200m max range), M750d/MT750d/MD750d (750kHz / 1.2MHz), M1200d/MT1200d/MD1200d (1.2MHz / 2.1MHz) and M3000d/MT3000d/MD3000d (1.2MHz / 3.0MHz, range resolution down to 2mm).
