This paper focuses on the different sensors and signal processing techniques to identify the working conditions of a hydraulic block. A Laser Doppler Vibrometer and a microphone are used to identify the sound pressure and the vibration velocity on the valve body. Tests showed that it is possible to identify different pressure and flow conditions through relying on time-frequency aggregated parameters.
