Meggitt 3223KGB02 N2 Variable Reluctance Speed Sensor Unit

Feature & Principle

This passive reluctance sensor has no internal electronics and requires no supply power. When gear teeth pass the probe tip, electromagnetic induction produces sine wave pulse output. The signal frequency corresponds to shaft rotational speed, sent to turbine control unit for speed indication, closed-loop regulation and overspeed trip protection.
