System and method for torque transducer and temperature sensor

A system, comprising:

• a magnetostrictive sensor head comprising:
• a driving coil coupled to a driving pole extending from a sensor head core, configured to receive a driving current, and configured to emit a magnetic flux portion through a rotary structure;
• a sensing coil coupled to a sensing pole extending from the sensor head core, wherein the sensing coil is configured to receive the magnetic flux portion, the sensing coil transmits a first signal based at least in part on the received magnetic flux portion, wherein the received magnetic flux portion is based at least in part on a force on the rotary structure at a section of the rotary structure opposite the magnetostrictive sensor head;
• and
• a temperature sensor coupled to the magnetostrictive sensor head, wherein the temperature sensor transmits a second signal based on heat emitted from the section of the rotary structure.

A method, comprising:

• generating a magnetic flux portion with a driving coil coupled to a driving pole of a magnetostrictive torque sensor;
• directing the magnetic flux portion through a rotary structure and a sensing pole of the magnetostrictive torque sensor, wherein the rotary structure comprises a ferromagnetic material;
• detecting the magnetic flux portion with a sensing coil coupled to the sensing pole, wherein the sensing coil is configured to generate a torque signal based at least in part on a torque on the rotary structure;
• measuring a temperature of the rotary structure with a temperature sensor disposed within the magnetostrictive torque sensor, wherein the temperature sensor is configured to generate a temperature signal;
• and
• determining the torque on the rotary structure based at least in part on the torque signal from the sensing coil and the temperature signal from the temperature sensor.
