Abstract: Optical sensor structure senses the presence of liquid in a sealed conservator tank. The sensor structure includes a sensor head having a body with first and second opposing ends, a plurality of perforations through the body and spaced between the first and second ends, and a mirror disposed at the second end. The perforations are constructed and arranged to receive and hold fluid therein. The sensor head is constructed and arranged to rest on a surface of a bladder. The sensor structure includes a light source, a first fiber optic cable between the light source and the first end of the body, a light detector, and a second fiber optic cable between the light detector and the first end of the body. The amount of light received by the light detector is reduced when liquid, instead of air, is in at least some of the perforations in the body.
