On the basic of theoretical analysis,optical fiber grating was combined with the fixed circular plate diaphragm,by measuring the offset of optical fiber grating center wavelength,pressure signal was got which liquid level produced,and then liquid level signal was obtained.
在此基础上将光纤光栅与周边固支圆平弹性膜片相结合,通过测量光纤光栅中心波长的偏移量,得出由液位而产生的压强信号,进而获得液位信息。
