Product Description
RA-3 Three-sided Rudder Angle Indicator(Dual Display)
Product Introduction
The Three-sided Rudder Angle Indicator (Dual Display) is an advanced marine navigation instrument engineered to deliver simultaneous, multi-perspective rudder position monitoring with the enhanced capability of displaying two separate angular ranges or operational modes on a single, integrated unit. This specialized design is critical for vessels with complex steering configurations or operational profiles requiring distinct rudder angle references.
Featuring a precision-engineered three-sided prismatic display window, this indicator presents clear, synchronized readings across three distinct viewing faces (typically covering a 120° to 150° viewing arc). Its core innovation lies in the dual display capability, which can be configured to show two different angular scales simultaneously—such as a standard ±35° scale alongside a high-resolution ±5° scale for precision maneuvering—or to display inputs from two independent rudder systems (e.g., main and emergency).
Housed in a rugged, flush-mount marine-grade enclosure, the unit is built to endure the harsh bridge environment, including vibration, salt spray, and wide temperature variations. Each viewing face features high-contrast, independently configurable dials with night illumination, ensuring instant readability from the central console, starboard, and portside vantage points.
