Abstract
Systems and methods for measuring torque on a drive train component of a rotating drive system are disclosed. In some aspects, a system includes a target assembly, a sensor assembly, and a sensor processing unit. The sensor assembly is located proximate to the target assembly, and the sensor assembly includes sensors mounted radially around the shaft and configured to detect sensor targets as the target assembly rotates with the drive train component. The sensor processing unit is configured for receiving sensor signals from the sensor assembly and outputting a torque signal based on the sensor signals. The sensor processing unit is configured for receiving target calibration data for the target assembly and sensor calibration data for the sensor assembly. The sensor processing unit is configured for verifying that the target calibration data corresponds to the target assembly and that the sensor calibration data corresponds to the sensor assembly.
