Abstract
A system for monitoring the bed health of a molecular sieve bed within a pressure swing adsorption (PSA) system includes an oxygen sensor coupled to an outlet of the PSA system. The oxygen sensor measures an oxygen concentration of an output air produced by the molecular sieve bed. A controller is in communication with the oxygen sensor and records a series of oxygen concentrations over time. The controller is configured to determine bed health based upon the series of recorded oxygen concentrations.
