Which fluxgate compass and rudder sensor for Raymarine model 100 autopilot
In article ,
"Lynn Coffelt" wrote: "luc" wrote in message ups.com... is a rudder angle sensor necessary for an autopilot? I thought the heading of the boat would be sufficient. There is no one sentence answer possible. Lots of boats steer to their owners satisfaction without a rudder angle sensor. Most boats steer better with a rudder sensor incorporated. Some boats can become absolutely unstable and dangerous under autopilot control, and in these boats, rudder angle input is absolutely necessary. It's hard to go wrong with the sensor, and with many vessels (and owners), a rudder angle indicator at helm stations is a great docking aid! Old Chief Lynn Just an note here.... Most of the Rudder Angle Sensers are just Linear Taper Pots, that drive a Feedback Loop in AutoPilot Rate Control Circuit, BUT the Wood Freeman RAS is very different, as it uses a Hall Effect Device, and is basically the same device as the one in the Steering Compass. They both feed OPAmps in the BrainBox. The Compass Senser drives the Course Feedback Loop, and the RAS feeds the Rate Feedback Loop, and the Rudder Angle Indicator Drive.
