10.9 Various other pickup / sensor installation possibilities

10.9.1 Hall-effect sensor

Typical hall effect sensor installation detects the passing of a magnet suitably fixed to prop flanges or shafts.

10.9.2 Gear tooth sensor

The gear tooth sensor is a popular pickup used on the pre-rotation gear of a gyro plane (rotor speed indication).

10.9.3 Optical Reflective Pickup

The optical reflective pickup can provide a simple means of contactless RPM sensing in difficult installations.
