ROTOR BLADE MONITORING SYSTEM, ROTOR BLADE MONITORING DEVICE, ROTOR BLADE MONITORING METHOD, PROGRAM

摘要

PROBLEM TO BE SOLVED: To improve detection accuracy of vibration amplitude of a rotor blade.;SOLUTION: An eddy current type first sensor detects passage of a rotor blade rotating about an axis, from a stator side in a noncontact manner. A second sensor has a smaller sensing region than that of the first sensor, and detects the passage of the rotor blade from the stator side in the noncontact manner. A rotor blade monitoring device generates a calibrated value of a detected value of the first sensor on the basis of a detected value of the second sensor, and outputs the calibrated value.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2019,JPO&INPIT
