[Problem] To provide a fueling device which can detect the inclusion of water in fuel oil and which is configured so that a sensor for detecting the inclusion of water is not necessary to have an explosion-proof structure. [Solution] The detection section (23a) of a sensor (23) for detecting the inclusion of water in oil is provided in a dangerous area, and devices (21, 22) for processing an optical signal from the detection section (23a) of the sensor (23) are provided in a non-dangerous area. The sensor (23) is provided with an optical fiber (23b) having the detection section (23a) provided at the tip thereof. The portion at which the optical fiber (23b) penetrates through the boundary between the dangerous area and the non-dangerous area can be sealed by a cable clamp (24). |
