Abstract
An improved oxygen analyzer includes a controller configured to receive an oxygen sensor signal and provide an oxygen concentration output. A probe is configured to extend into a source of combustion process gas. An oxygen sensor is disposed within the probe and has a sensing electrode mounted to one side of a solid electrolyte and a reference electrode mounted to an opposite side of the solid electrolyte. The oxygen sensor has catalytic beads that are configured to be disposed between the process gas and the sensing electrode. Measurement circuitry is operably coupled to the oxygen sensor and the controller and is configured to provide the controller with the oxygen sensor signal based on an electrical response of the oxygen sensor. The controller is configured to detect a behavior of the oxygen sensor concentration output over time to provide at least one ancillary output.
