Abstract
A torque sensing device for measuring the torque applied to a rotatable shaft, and also measuring the magnetic field noise affecting the device. The device incorporates a switching function thereby enabling the device to operate in a common signal detection mode and a differential noise detection mode. The device is capable of determining the torque applied to the rotatable shaft based upon output signals obtained from magnetic field sensors operating in both the common signal detection mode and the differential noise detection mode. The device is capable of accurately measuring a torque induced magnetic field and is capable of canceling measurement error resulting from noise induced magnetic fields.
