Abstract
A stress sensing system for measuring stress in a conductive target material includes at least one sensor positioned proximate to the conductive target material. The sensor is configured to measure stress in the conductive target material and to transmit a signal indicative of the measured stress to a controller. The controller is coupled in communication with the sensor. The controller is configured to receive the signal from the sensor, determine a runout portion of the signal corresponding to the runout of the conductive target material, determine a runout pattern waveform from the runout portion, and subtract the runout pattern waveform from the signal.
