I'm familiar with variable reluctance sensors. I believe that's what you're
referring to. They produce a signal that increases in frequency and amplitude
as the rpms increase. Signal conditioning is required to prevent the high
voltage produced from exceeding the limits of a uC.

Subject: [AR] Speed sensor for pump shaft
Anyone have any experience with a magnetic speed sensor? This type of
sensor you magnetize the end of your shaft with a permanent magnet and
the flux produced is used to get the rotational value.
