Abstract
A sensor to sense pressure in a pressure bottle and a method of assembling the sensor involve two or more fiber Bragg gratings (FBGs) affixed to a different radial location of a diaphragm seal of the pressure bottle. The sensor includes a light source to provide incident light to the two or more FBGs, and a photodetector to detect reflected light resulting from the two or more FBGs. Processing circuitry determines a pressure change in the pressure bottle based on the reflected light resulting from each of the two or more FBGs.
