Torsional vibration measurements are used to determine the natural frequencies and mode shapes of a rotor train as it twists about the axis of rotation. The shaft is instrumented with either strain gages or accelerometers at one or more locations. Signals from the rotating sensors are transmitted to a stationary data acquisition system by radio telemetry. Our torsional vibration measurement service may also be used to determine shaft torque, shaft bending strain and turbine blade vibration.
