What is it sensing as the turbine spins ? Infrared ? Ultrasonic ? Magnetic ? And since the sensor is fixed in position, while the turbine pivots with the wind direction, how does that work ?

      I have a 2315 but I've never torn it apart.

      From what I've seen, Dimitris (Weather 1967) has torn apart and rebuilt 23XX stations several times and he seems expert in how they work. He has some diagrams on his website:


      or you might email him. Or he may respond to this post.

      Good luck! :)
