The rudder angle indicator and transmitter are key supporting components of the ship's instrument system, specially developed and designed for various ship navigation and control scenarios. The transmitter accurately collects the rudder blade angle signal, processes it and transmits it to the indicator, realizing real-time visual display of angle data, allowing the crew to intuitively grasp the steering gear status and provide accurate basis for ship steering, avoidance and other control actions. The product has significant core advantages, stable working performance, not affected by strong marine electromagnetic interference, and easy to operate, which can be used without complex training. High-strength corrosion-resistant alloy materials are selected to effectively resist salt spray and moisture erosion, adapting to long-term marine operation environments. Compact and lightweight structure, small installation space, compatible with most ship instrument interfaces, low maintenance c…
