DT101Xi / DT102Xi Multibeam Profiling Sonar
Multibeam echo sounders integrating sonar, motion reference unit and sound velocity sensor in one compact single-cable unit for bathymetric survey.
Description
The DT101Xi and DT102Xi are multibeam profiling sonars (multibeam echo sounders) that integrate the sonar, an internally mounted OEM motion reference unit and an internally mounted OEM AML Micro•X sound velocity sensor in one compact unit operated over a single cable. Used with the DT100 SIR power supply/timing box, only a dual-antenna GNSS/GPS receiver is needed to perform bathymetric surveys.
Key features
- DT101Xi: 120° swath at 240 kHz; DT102Xi: 180° swath at 675 kHz
- Up to 480 beams (selectable 240, 120)
- MRU pitch and roll accuracy 0.04°; heave 5 cm or 5%
- Sound velocity 1400-1600 m/s ±0.025 m/s
- 300 m depth rating; Ethernet (100 Mbps) TCP/IP
