Product Description
RA-1G Wall Type Rudder Angle Indicator
Product Introduction
The Wall Type Rudder Angle Indicator is a robust, high-visibility instrument designed for critical rudder position monitoring on ships, offshore platforms, and marine control stations. Engineered for durability and reliability in demanding marine environments, this standalone unit provides real-time, precise visual feedback of the rudder angle for safe navigation and maneuvering.
Featuring a compact yet sturdy wall-mounted enclosure, this indicator is ideal for installation in steering gear rooms, engine control rooms, aft control stations, or any auxiliary location where continuous rudder monitoring is required—without occupying valuable console or bridge panel space. Its distinct design allows for flexible placement while ensuring excellent visibility from various angles.
The instrument incorporates a large, clear dial calibrated from 35° port to 35° starboard, with bold markings and a highly contrasting pointer for instant readability even from a distance. Many models include dual-scale illumination for round-the-clock operation. It connects directly to the vessel’s rudder feedback system, delivering accurate and synchronized angle display to support both primary and backup steering operations.
