Abstract
A gauge system comprises a sensor that produces a sensor signal as a function of a sensed parameter. The gauge system also comprises a motor and a gauge having a scale and a movable indication needle that is driven by the motor and displays a measurement value of the sensed parameter based upon position of the needle relative to the scale. The gauge system further includes a position sensor that produces a position feedback signal representative of a sensed position of the needle and a controller that provides drive commands to the motor based on the sensor signal and the position feedback signal.
