Document Type and Number:
WIPO Patent Application WO/2021/085015
Kind Code:
A1
Abstract:
This detection device is for detecting the timing of the passage of a turbine blade. The detection device comprises: a sensor that includes a magnet and a coil which is disposed at a position subject to the magnetic flux generated by the magnet and which is configured so as to detect an induced electromotive force based on a change in the magnetic flux accompanying the passage of a turbine blade; and a analyzer configured so as to detect the timing of the passage of a turbine blade on the basis of an integrated signal obtained by integrating a signal based on the induced electromotive force.
