Abstract
A gap compensated stress sensing system and methods for using the same are provided. The system can include a sensor head in communication with a controller. The sensor head can contain a stress sensor configured to generate a stress signal representing stress applied to a target based upon measurement of generated magnetic fluxes passing through the target. The system can also include a drive circuit configured to provide a current for generation of the magnetic fluxes, and to measure signals characterizing a gap between the sensor head and the target. The controller can analyze these signals to determine a gap-dependent reference signal that is relatively insensitive to electrical runout. The controller can further adjust the stress signal based upon the gap-dependent reference signal to determine an improved stress signal that has reduced sensitivity to gap changes.
