Furuno DS 50 Doppler Speed Log Display – Marine navigation instrument used to show vessel speed and log data, typically part of the DS-50 Doppler Speed Log system.
Measures and displays the vessel’s speed relative to ground and water using the Doppler effect sonar.
Provides speed fore/aft and port/starboard, as well as distance run and keel clearance (depth).
Ultrasonic frequency: 440 kHz
Number of beams: 3 beams for dual-axis speed indication (fore/aft and port/starboard)
Fore/Aft ship’s speed range: –10.0 to +40.0 kn
Port/Starboard speed range: –9.9 to +9.9 kn
Speed accuracy: ±1 % or ±0.1 kn (whichever is greater) – with typical vessel motion allowances (rolling±10°, pitching±5°)
Ground tracking depth: 1 m to 200 m beneath the keel
Water tracking depth: 3 m to 25 m beneath the hull (varies with installation & water conditions)
Total distance run (log): 0 to 99 999.99 nautical miles
Main display: LED (orange) for numeric speed and status
Digital indicators: LCD or LED options
Nominal viewing distance: ~1 m
Brightness control: Duty-cycle ON/OFF dimming
Inputs
External keying pulse: 2 ports
Outputs
Ship’s speed: 2 digital ports, 1 analog port (or distributed via optional box)
Distance signals:
1 × 400 p/NM (forward only)
6 × 200 p/NM (contact closure)
Alarm signal (contact closure)
Keying pulse output: 1 port
Digital Interface
2 × IEC 61162-1 (NMEA0183) ports
Output sentences: VBW, VTG, VHW, VLW (VTG only if seabed echo is acquired)
AC power: 100/110/115/220/230 VAC, 50/60 Hz
Ambient temp: –15 °C to +55 °C
Humidity: Up to 95 % at 40 °C
Designed per IEC standards (e.g., IEC 945 test methods). Performance may be affected by air bubbles and interference.
