The MP-981 is a magneto- type detector using a hall element which is suitable for revolution(r/min) measurement from low speed to high speed. Magneto-type detectors use an internal hall element, a permanent magnet, DC amplifier, and voltage regulator and respond to flux, so that a rectangular wave form is derivable from much lower speed all the way though high speed.
