PRODUCT NAME : SPERRY MARINE MASTER DISPLAY UNIT SRD 331 WITH DROPPLER SPEED LOG ELECTRONICS UNIT SRD-331
COMPANY NAME : SPERRY MARINE
MODEL NUMBER : SRD-331

PRODUCT DESCRIPTION :

The SRD 331 Master Display Unit is a central component in Sperry’s navigation system. It serves as the main interface for monitoring a variety of critical data onboard, including speed, heading, and other navigational information. The Master Display integrates data from various sensors, including radar, gyrocompasses, and speed logs, into one cohesive display. This allows operators to monitor vessel performance, track speed, and receive alerts or warnings about system status or abnormalities.

The SRD-331 Doppler Speed Log Electronics Unit is designed to provide precise vessel speed measurements through Doppler radar technology. This system uses the Doppler effect to measure the velocity of the ship relative to the seabed, providing accurate, real-time speed data. The system is particularly useful for determining the vessel’s speed through the water, which is essential for navigation, performance monitoring, and ensuring regulatory compliance.
