Rudder angle: precision and control of your steering system

Rudder angle is crucial for optimizing sail trim, monitoring autopilot performance, and anticipating boat reactions. At Skysat, drawing on our extensive offshore racing experience, we know that precise and reliable information is essential for smooth and efficient sailing. Here, we offer a selection of robust and accurate rudder angle sensors, along with advice on their optimal integration into your navigation system.

choosing the right bar angle sensor

Choosing a rudder angle sensor depends on several factors, including the type of steering system on your boat, the communication protocol of your onboard electronics (NMEA 2000, SeaTalk NG), and the desired accuracy. A well-suited sensor ensures reliable information that is easily usable by your navigation instruments.

• Rotary potentiometer sensors: A simple and economical solution, ideal for mechanical steering systems. Requires precise calibration and protection against moisture.
• Hall effect sensors: More robust and precise than potentiometers, they offer better resistance to vibration and wear. Compatible with NMEA 2000 systems via a suitable interface.
• Digital angle sensors: Integrate an analog-to-digital converter for direct data transmission in NMEA 2000 or SeaTalk NG. Offer high accuracy and immunity to interference.
• Bar angle interfaces: Allow you to convert the analog signal from an existing sensor into a digital signal compatible with your NMEA 2000 network.

integration and calibration

Proper installation and rigorous calibration are essential to ensure the accuracy and reliability of your rudder angle sensor. Alignment of the sensor with the rudder's rotation axis, supply voltage, and communication protocol configuration are all points that must be carefully checked.

• Sensor alignment: Ensure that the sensor's rotation axis is perfectly aligned with the rudder's rotation axis to avoid measurement errors.
• Power supply: Check the sensor's supply voltage and use a stabilized power supply to avoid fluctuations.
• NMEA 2000 Configuration: Properly configure the sensor on your NMEA 2000 network using the appropriate diagnostic tool. Verify the PGN (Parameter Group Numbers) sent by the sensor.
• Calibration: Calibrate the sensor following the manufacturer's instructions to compensate for installation errors and temperature variations.

diagnostics and maintenance

Even the most robust sensors may require periodic maintenance to ensure their long-term performance. Regularly check the condition of connections, for corrosion, and the accuracy of measurements. Accurate diagnostics allow for the early detection of problems and help prevent breakdowns at sea.

• Checking connections: Regularly inspect electrical connections for corrosion or loose wires.
• Accuracy test: Compare the values ​​displayed by the sensor with a known bar angle to verify its accuracy.
• Cleaning: Regularly clean the sensor with a soft, dry cloth to remove dust and dirt.
• Replacing worn parts: Replace worn parts, such as potentiometers or bearings, to maintain sensor performance.

💡 Skysat's advice

When integrating a rudder angle sensor into an NMEA 2000 network, ensure compatibility with other instruments. An NMEA 2000 multiplexer may be necessary to manage ID conflicts and optimize data flow.
