Hello,
Is there anything behind using toothed wheel infront of magnetic pickups for measuring speed in hydro turbine shaft?

- Use of VT signal is the other one that I have seen, as it provides a more stable signal. This doesn't work so well at low speeds prior to application of excitation. It's common to use this in combination with mag pickups (switching over to the VT once a stable signal is achieved).
- A small permanent-magnet generator coupled to the shaft, connected to a small motor in older mechanical governor systems.
