Abstract

A device to determine rotational parameters of a rotatable shaft mounted within a stationary tube comprising a substantially annular shaped target. The target is attached to a rotatable shaft. A target retainer has a bore for receiving the rotatable shaft, and is dimensioned to be securely attached to an interior surface of the tube. The target retainer has a radially extending surface adjacent each axial end of the target to restrain axial movement of the target, and also has an aperture adjacent the outer periphery of the target. A sensor extends into the aperture when the sensor is mounted on the stationary tube. Fasteners connect the sensor to the stationary tube.
