Abstract
A shrouded turbine blade vibration monitoring system is comprised of a plurality of sensors for sensing a profile of a turbine blade row. A microprocessor compares the sensed profile to an expected profile of the turbine blade row to detect motion of the turbine blades due to vibration. The microprocessor then generates an operator alarm and trips the turbine in response to the detection of unacceptable vibration of the turbine blades.
