提出了一种基于倾斜光纤光栅的新型油位监测传感器。通过改变倾斜光纤光栅的长度和数目，可以实现油位测量范围和灵敏度的调制。油浸状态下，串式TFBG的透射光谱随油位的变化而发生明显的变化。实验是在三个2cm长的串联TFBG上进行的，倾角均为10 °。利用TFBG具有峰-低值的频谱特性，在线性良好的情况下，获得了3.28dB/cm的灵敏度。包层模传输功率和高阶包层模谐振幅度与油位变化近似成线性关系。这种传感器对温度不敏感，适用于极端恶劣环境下的油液监测。
In this paper, we present a novel oil level monitoring sensor based on string tilted fiber Bragg grating (TFBG). The measurement range and sensitivity of oil level monitoring can be modulated via changing the length and number of string tilted fiber gratings. The transmission spectrum of string TFBGs immersed in oil changes obviously with the oil level variation. Experiments are conducted on three 2 cm-length serial TFBGs with the same tilted angle of 10o. A sensitivity of 3.28 dB/cm in the string TFBG sensor is achieved with good linearity by means of TFBG spectrum characteristic with peak-low value. The cladding mode transmission power and the amplitude of high order cladding mode resonance are nearly linear to the oil level variation. This kind of sensor is insensitive to temperature and attributed to be employed in extremely harsh environment oil monitoring.
