The S.E.P. (Societe Europeenne de Propulsion) develop and manufacture cryogenic engines for the 'Ariane' European Space Agency launcher. Since the late 80s the C.N.E.S. (Centre National des Etudes Spatiales), the French Space Agency, has supported the development of fiber optic sensors for the future missions, exploration and diagnosis of spacecraft engines. The environmental conditions in a cryogenic engine are extreme in terms of temperature range, pressure, and vibration levels. We have shown that fiber optics sensors can be ideally suited in these harsh environments. Hence we present in more detail a fiber optic pressure probe that has been developed for engine in-situ measurements.
