RA-1G Wall Type Rudder Angle Indicator (Weather-proof)
Product Description
RA-1G Wall Type Rudder Angle Indicator (Weather-proof)
Product Introduction
The Weather-proof Wall Type Rudder Angle Indicator is a robust and essential monitoring instrument designed to deliver reliable rudder position feedback in the most demanding marine and offshore environments. Engineered for durability and clarity, this standalone unit provides continuous, accurate visual indication of the rudder’s angle, ensuring operational safety and precise maneuverability, even when installed in exposed or semi-exposed locations.
Housed in a sealed, corrosion-resistant enclosure, this indicator is specifically built to withstand harsh conditions including driving rain, salt spray, high humidity, and temperature variations. Its wall-mounted design allows for versatile installation in critical areas such as steering gear rooms, aft control stations, bridge wings, engine control rooms, or any auxiliary location where continuous rudder monitoring is required—freeing up valuable console space on the main bridge.
The instrument features a large, high-contrast dial with clear calibrations (typically 35° port to 35° starboard) and a bold pointer for excellent readability from a distance and in low-light conditions, with optional internal illumination for 24/7 operation. It interfaces directly with the vessel’s rudder feedback system, providing real-time and synchronous angle display to support both primary and backup steering operations.
