摘要： Magnetic field sensor feedback for diagnostics is disclosed herein. A disclosed example apparatus includes a first magnetic field sensor to provide a first output signal in response to a magnetic field generated by a magnet coupled to a movable portion of a process control device, and a second magnetic field sensor to provide a second output signal in response to the magnetic field. The disclosed example apparatus also includes a processor to use the first and second output signals to generate diagnostic information associated with a feedback of the process control device.
