摘要： A system or method for sensing rotational parameters of a rotating machine. A rotating element is mounted on a shaft of a rotary machine. The rotating element has predetermined magnetic permeability. An insert is disposed on the first rotating element and characterized by a second magnetic permeability different from that of the rotating element. A sensor is mounted opposite the first rotating element and separated from the rotating element by a gap. The target element has an axis substantially parallel with and offset from the axis of the rotating element. The sensor is disposed in substantial alignment with the target element at least once per rotation when the rotating element is rotating. The sensor is configured to generate an output signal in response to a sensed deviation in a magnetic field induced by the rotation of the target element in proximity to the sensor.
