A High-Sensitivity Fiber Grating Pressure Sensor and Its Pressure Sensing Characteristics
摘要
采用增敏罐封装的方法,设计并研究了一种新型高灵敏度的光纤光栅压力传感器,其压力灵敏系数可高达-3.41×10-3 MPa-1(相应于灵敏度-5.277 nm/MPa),压力灵敏系数较裸光纤提高了1722倍,且线性度良好,可应用于低压情况下物理量的传感测量.
Abstract
A high sensitivity fiber grating pressure sensor using the enhance-sensitivity-coated jar has been designed and studied. The pressure sensitivity is up to -5.277 nm/Mpa, which is corresponding to the sensitivity coefficients of -3.41×10 -3 Mpa -1. The sensitivity is about 1722 times the value of the bare fiber. The linearity is very good. This kind of sensor has potential applications in the sensing measurement at low-pressure.
