Strain gages and thermocouples are attached to the blades to measure dynamic strain and temperature as the blades rotate and vibrate.
The gages are connected to a radio telemetry system that transmits signals from the rotating shaft to a stationary data acquisition system. A variety of excitation systems including air, oil and steam jets, and electric magnets are used to stimulate vibration of the rotating blades.
Services Include
- At-speed natural frequency measurements
- Strain gage radio telemetry
- Spin pit measurements
- Operating plant measurements
- Air jet excitation
- Steam jet excitation
- Magnetic excitation
