FIELD: pressure measuring.
SUBSTANCE: invention relates to the field of measuring hydrostatic and rapidly changing pressure using optical means. The sensor contains two sensitive elements (SE) of pressure and temperature, based on the Fabry-Perot interferometer (FPI) in such a way that the second reflective surface of the FPI of the first SE is simultaneously the first reflective surface of the FPI of the second SE.
EFFECT: improving the accuracy of temperature and pressure measurements.
