Abstract

A temperature compensated torque sensing system and methods (700) for using the same are provided. The system can include a sensor head (202,300) in electrical communication with a controller (114,204). The sensor head (202,300) can contain a torque sensor including a core, a driving coil (212) and a sensing coil (214,502). The sensor head (202,300) can also include a temperature sensor (112,216,400,500) coupled to the sensor head (202,300). The torque sensor can be configured to measure torque applied to a selected portion of a target (222) based upon magnetic flux passing through the target (222), while the temperature sensor (112,216,400,500) can be configured to concurrently measure the target temperature. The temperature sensor (112,216,400,500) can be positioned for avoiding interference with sensed magnetic flux. The controller (114,204) can adjust the determined torque using the temperature measurements to compensate for changes in magnetic properties of the target (222) due to variation in target temperature. In this manner, the accuracy of the torque measurements can be increased.
