Aiming at limitations and disadvantages of traditional non-contact eddy current testing( ECT) sensors for axis orbit detection
a new type of sensor based on permanent magnet perturbation( PMP) theory is proposed.The working principles
sensor structures and detection method are presented in detail and respectively. By comparing with ECT sensor and analysis of testing results of PMP sensor
it is found that the new PMP sensor has higher reliability of detection and better operability. Therefore
the proposed new sensor may have great promise in the future engineering practice.
