Abstract

See full text

According to some embodiments, a method for determining a fault status of a target system can include: receiving one or more magnetic field signals sensed by one or more magnetic field sensing elements of a sensor, the one or more magnetic field signals responsive to a magnetic field generated by a target object of the target system, the target object having repetitive motion; processing the one or more magnetic field signals to detect values of one or more parameters indicative of vibration of the target system; calculating deviations between the detected values and corresponding reference values of one or more parameters; determining a fault level of the target system based on the calculated deviations of one or more parameters; and generating an output signal indicating to the fault level.
