ABSTRACT:
A torque sensing assembly (10) includes a first sensor assembly (50) configured for sensing at least a portion of a magnetic field of a first portion (22) of a rotating shaft assembly (12) and generating a first signal (52). A second sensor assembly (56) is configured for sensing at least a portion of a magnetic field of a second portion (26) of the rotating shaft assembly (12) and generating a second signal (58). A common mode detection circuit (54) is configured for combining the first and second signals to form a combined signal and processing the combined signal to at least partially remove a common mode signal from the combined signal and generate an output signal.
