Abstract
A process and a computer implemented system for monitoring vibration in the blades of the rotor and stator of an axial compressor through measurement of pressure fluctuations of the dynamic pressure field in the region of the compressor housing in at least one stage of the compressor by means of at least one pressure sensing device sensitive to differential pressure fluctations affecting the blades at the characteristic frequency of the stage. The process and computer implemented system also assist in the control of the compressor by forwarding a status respecting rotor and stator mechanical vibration to the control unit.
