Abstract: A sensor system configured to detect oxygen in an exhaust stream of an industrial process is provided. In one embodiment, the sensor system comprises a probe with an oxygen-detecting sensor, wherein the oxygen-detecting sensor detects a concentration of oxygen in the exhaust stream. The system may also comprise a catalytic converter located on the probe near the sensor, wherein the catalytic converter is configured to convert carbon monoxide to carbon dioxide. The system may also comprise a signal detector configured to detect a change in oxygen concentration indicative of a carbon monoxide breakthrough.

Abstract: A process analytic instrument includes a measurement cell and an analyzer circuit. The measurement cell includes a solid state electrochemical oxygen sensor configured for exposure to a process gas. The analyzer circuit is coupled to the solid state electrochemical sensor to measure an electrical parameter of the solid state electrochemical sensor and provide an output indicative of oxygen in the process gas. A DC bias circuit is configured to selectably bias the solid state electrochemical oxygen sensor with a direct current when the solid state electrochemical sensor is in a reducing environment.
