Abstract
A moveable body, cladding medium, and fiber are arranged to form a sensor suitable for use in monitoring changes in liquid, fluid, and material level and changes in pressure. The moveable body moves in response to changes in pressure or force. Movement of the body causes a change in the length of cladding medium surrounding an optical fiber. As the extent of cladded fiber length changes, the intensity of light transmitted through the fiber also changes.
