881A / 881L Profiling Sonar
Programmable multi-frequency digital profiling sonar heads (600 kHz–1 MHz) with serial or Ethernet interface.
Description
The Model 881A Profiling Sonar Head is a programmable multi-frequency digital scanning sonar that lets operators fine-tune profiling range resolution, using default settings or custom configurations tunable from 600 kHz to 1 MHz in 5 kHz steps. It offers high performance, low power and simple set-up for profiling applications. The 881L Profiling version uses Ethernet communications.
Key features
- 675 kHz default frequency
- Beam width 2.4° (600 kHz), 2.1° (675 kHz), 1.4° (1 MHz)
- Range resolution 2 mm at 1-4 m, 10 mm from 5 m
- 20-36 VDC at less than 5 W
- 79.4 mm diameter x 234 mm length; 1000 m and 3000 m depth ratings
Applications
Seabed, structure and trench profiling from ROVs and fixed platforms. Specifications listed are for the 881A Profiling.
