An optically powered pressure sensor for sensing pressure of a liquid in a tank includes a hermetically sealed housing with at least a portion of the housing having a diaphragm, at least one sensor within the hermetically sealed housing, at least one optical emitter, and a photocell array. The hermetically sealed housing forms at least a portion of a hermetically sealed wall of the tank. The at least one sensor within the hermetically sealed housing is configured to sense the pressure of the liquid. The at least one optical emitter is configured to transmit data corresponding to the sensed pressure. The photocell array is configured to receive light and provide power to the at least one sensor and the at least one optical emitter.
