881L Multi-Frequency Imaging Sonar
Ethernet multi-frequency digital imaging sonar exceeding 100 shots per second at 1 m range with 2 mm resolution.
Description
The 881L is an all-in-one digital imaging sonar using Ethernet communications. It can exceed 100 shots per second on the 1 m range at 2 mm range resolution, producing near-photographic image quality. It is multi-frequency, operating on default settings (310 kHz, 675 kHz or 1 MHz) or custom configurations tunable from 280 kHz to 1.1 MHz in 5 kHz steps. Cable length can be extended to about 9000 m with an Ethernet extender; narrow-beam and 6000 m variants are offered.
Key features
- 10 Mbps Ethernet (10BASE-T) TCP/IP
- Range resolution 2 mm at 1-4 m, 10 mm from 5 m
- 1000 m and 3000 m depth ratings
Applications
Imaging for large work ROVs, small inspection vehicles, AUVs and UUVs. Specifications listed are for the 881L Imaging.
