Abstract : This paper introduces the benefits of applying the optical fiber Fabry-Perot interferometer (FFPI) pressure sensor as a means of detecting flow instabilities in centrifugal pumps and compressors. Actual pump test data will be presented, demonstrating how harmful hydraulic instabilities, such as cavitation and low flow instabilities, can be readily detected using this new sensor. The authors will explain how centrifugal compressors can be protected from surge by sensing flow reversals with an FFPI differential pressure sensor. Also covered is how the FFPI pressure sensors can be integrated into a complete FFPI monitoring system capable of sensing bearing housing vibration, shaft vibration, and shaft rotary speed.
