Optical measurement of pressure transient-induced flow in hydraulic systems

The project is concerned with observation of fluid movement and transducer diaphragm deformation, under the influence of large pressure transients of the order of 2000 PSI (140 bar). Large pressure surges often occur in hydraulic systems and this coupled with sharp rise times of the order of 100 μs, causes damage to the surface of the transducer diaphragm or face and subsequently the pressure reading mechanisms.
