Abstract
A torque sensor assembly comprises a shaft configured to receive an applied torque. The shaft comprises at least one region, which is magneto-elastic and configured to generate a magnetic field in response to the applied torque. A pair of sensing coils disposed adjacent to the region is configured to sense the magnetic field. One or more sensors sense a temperature of each of the sensing coils. A controller is coupled to the pair of sensing coils and the sensor(s). The controller is configured to receive the sensed temperature of each of the sensing coils, determine a temperature difference between the sensing coils and generate an output signal based on the sensed magnetic field. The output signal accounts for the temperature difference between the sensing coils.
