Abstract:
The present invention relates a fiber optic transducer (FOT) and methods for measuring the pressure and temperature of a flowing fluid using such FOT, wherein such FOT contains a fiber optic having fiber Bragg gratings. The fiber Bragg gratings are measured during a flowing fluid to determine the difference in the change in wavelength exhibited by a reflected optical signal from the gratings.
