PURPOSE: A liquid level measuring sensor made of optical fiber is provided to reduce axial rigidity by being made of optical fibers formed in a periodic shape such as a helix or waves of trigonometric function. CONSTITUTION: A liquid level measuring sensor(100) made of optical fiber comprises an optical fiber(110), an optical source(120), an optical sensor(130), and a fixing member(140). The optical source is coupled with one end of the optical fiber. The optical sensor is coupled with the other end of the optical fiber. The fixing member is fixed with the side end or middle end of the optical fibers. The optical sensor is attached to the receiving surface of the optical fiber. |
