摘要： A sensor includes a shaft and a magnetic sensor and an anti-aging magnetic sensor. The shaft may have at least one magnetized active region. The magnetic sensor may be configured to sense a magnetic field about the shaft, and may provide an output representative of torque applied to the shaft, shaft rotational speed and/or shaft rotational position. The anti-aging magnetic sensor may be positioned adjacent the active region to provide a reference signal output that is substantially independent of torque applied to said shaft.
