| description | To provide a fluid liquid level sensor capable of at least detecting a penetration position of an oil in an oil detection region.SOLUTION: A fluid liquid level sensor includes an optical fiber sensor having optical transmittance changed by attachment of an oil, a light emission unit that emits inspection light to one end of the optical fiber sensor, a light-receiving unit that receives the inspection light incident from the other end of the optical fiber sensor, a plurality of optical units that are arranged so that the optical fiber sensors cross each other in the oil detection region, and a monitoring circuit that detects a penetration position of the oil in the oil detection region on the basis of a light-receiving signal input from the light-receiving unit to notify an outside of the penetration position.SELECTED DRAWING: Figure 1
【課題】油検知領域における油の浸入位置を少なくとも検知することが可能な流体液面センサを提供する。【解決手段】油の付着によって光透過率が変化する光ファイバセンサと、該光ファイバセンサの一端に検査光を出射する光出射部と、前記光ファイバセンサの他端から入射する前記検査光を受光する受光部とを備え、光ファイバセンサが油検知領域において互いに交差するように配置さる複数の光学ユニットと、受光部から入力される受光信号に基づいて油検知領域における油の浸入位置を検出して外部に通報する監視回路とを備える。【選択図】図１ |
