摘要
对一种叶片阻尼式光纤束差压传感器进行了设计与研究。首先设计基于叶片阻尼式的传感器探头结构,分析了传感器探头的工作原理;再对传感器系统进行设计,对传感器输出信号进行强度补偿;然后建立了强度调制模型,在此基础上,对影响传感器主要性能的参数R、e、r、k等进行了实验分析,得出了不同参数时的Δp-M曲线。实验结果表明:各参数取为定值时,传感器输出值随着压差的增大而减小,传感器的灵敏度大小取决于主要性能参数的选取,不同的性能参数下传感器线性度均较好。研究证明,该传感器结构能适用于不同压差检测场合的需要。
In this paper,a kind of optical fiber bundle differential pressure sensor with blade damping was designed and studied.First,a sensor probe structure based on blade damping was designed,and the working principle of sensor probe was analyzed;Then the sensor system was designed,and the output signal of the sensor was compensated.Then the intensity modulation model was established,on the basis of this,the parameters such as R、e、r、k which affect the main performance of the sensor were analyzed,and theΔp-M curves of different parameters were obtained.The experimental results show that when the parameters are taken as fixed values,the output value of the sensor decreases with the increase of the pressure difference.The sensitivity of the sensor depends on the selection of the main performance parameters,and the linearity of the sensor is good under different performance parameters.It is proved that the structure of the sensor can be applied to the needs of different pressure differential detection situations.
