Abstract

PURPOSE: To ensure the safety of a moving vane, by installing a strain gauge and a piezo-electric element at a location, at where stress maximally changes, such as a root portion of the moving vane, and by guiding the variation signals to the outside.
CONSTITUTION: The output of a strain gauge 7 mounted to a root portion, etc. of a moving vane is guided to a transmission antenna 8 through a transmitter 6. Signals received by means of a receiving antenna 10 are conducted to an analysis instrument 11. The rest is connected through a transducer 12 necessary for an automatic register 13, a load limit device circuit 14 and an alarm device 15. When a level of the vibration of the moving vane becomes abnormal, this device can rapidly be responded to the abnormality.
