Abstract
A method and system for measuring a characteristic of a machine is provided. The system includes a speed sensor including a housing, a variable reluctance sensor (VRS) mounted at least partially within the housing, and a digitization circuit electrically coupled to an output of the VRS. The digitization circuit is also mounted within the housing and is configured to convert a substantially sinusoidal output of the VRS into a digital output signal.
