Description
Potentiometric Sensing and Signal Analysis
Autopilot systems lacking direct rudder position data frequently suffer from over-steering and course hunting in heavy following seas. The Simrad RF300 Rudder Feedback unit provides high-precision potentiometric data to the course computer. This sensor ensures absolute rudder angle telemetry for stable navigation.
The unit integrates via a two-wire frequency interface compatible with NAC-2 and NAC-3 autopilot processors. High-resolution internal components translate physical rudder movement into a frequency signal ranging from 2900Hz to 3900Hz. Ruggedized polymer construction ensures protection against the high-humidity environments found in maritime bilge compartments.
Strategic Vessel Application
Mandatory for Simrad autopilot systems requiring physical rudder position feedback for non-virtual feedback configurations.
Technical Key Features
- Frequency output ranges from 2900 to 3900Hz
- Potentiometric sensor provides absolute rudder angle data
- Corrosion resistant housing protects internal electronic components
- Adjustable linkage arm simplifies rudder post installation
- Transmits real time data via two wire interface
- Low profile design facilitates mounting in restricted bilges
- High resolution telemetry eliminates autopilot steering hunting
