Hello! The ship's rudder degree indicator, known as "rudder angle indicator" or "rudder angle indicator", is a device that shows the angle of the ship's rudder relative to its longitudinal axis. This device helps the captain and crew to know the position of the ship's rudder and how the ship is turning or heading straight. Here is a complete description of this device: ### Structure and components 1. Galvanometer: In this system, a galvanometer plays the main role. A galvanometer is a measuring device used to detect and measure small electric currents. Here, a galvanometer is used to indicate the rudder angle. 2. **Angle sensors 3. **Unit 4. Display ### instruction 1. Detecting the rudder angle: 2. Signal conversion: 3. Signal processing 4. Display angle: ### Benefits and uses 1. Accuracy: 2. Safety: 3. Wide application:
