    • 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.

    • A speed sensing seal with a first support member, a second support member, a magnetic elastomer member, a sensor member and an elastomeric seal member is disclosed. The magnetic elastomeric member with alternating adjacent poles is formed on the first support member and the sensor member is attached to an aperture in the second support member and overmolded with a layer of elastomer. The first and second support members are formed in the unitized body to form an internal cavity which contains the sensor, magnetic member, and the elastomeric seal. The first support member has a low wear surface to reduce initial seal failures and to enhance seal life.
