SYSTEM AND METHOD FOR MONITORING TURBINE BLADE

摘要

A system for monitoring mechanical stress on a turbine blade is disclosed. The system includes a ferromagnetic blade mount, a magnetic sensor, and a processor. The ferromagnetic blade mount includes a magnetically encoded region. The magnetic sensor is configured to measure magnetic flux linked with the magnetically encoded region. The processor is communicably coupled with the magnetic sensor to compute a blade health indicator based, at least in part, on the measured magnetic flux.
