Abstract

A pressure and temperature sensing system based on fiber-optic Bragg grating sensors for the oil and gas downhole is reported in this paper, the weak pressure sensitivity is enhanced and the cross-sensitivity of temperature and pressure measurands is overcome by an optimally designed mechanical enhancing and compensating structure, the working principle, experimental setup and testing results are also given.
