- In this paper, the performance of a self-gain optical fiber differential pressure sensor based on damping piston is studied. Firstly, proposes the structure of mechanical packaging sensor probe based on the damping piston, and designs the sensor system; then, it carries out the theoretical research on the sensor and builds the intensity compensation modulation of the sensor. Finally, the experimental model machine is used for the strength compensation test and the differential pressure test. The experiment results show that after the intensity compensation of sensor, the output value can be maintained at a constant value, which is not affected by the fluctuation of light source power, and the output value can achieve the gain; the sensor of damping spring in different designed sizes has different detection range. When the detection range is [-80KPa, 80KPa], the sensitivity is about 0.024/KPa and the linearity is about 6%, with a good sensitivity and linearity. The research shows that the optical fiber differential pressure sensor has better detection performance and can meet the needs of different detection occasions.
