摘要： An exhaust gas sensor element having an electrochemical cell, a protective material in fluid communication with the electrochemical cell, and a reactive inhibitive coating disposed over the protective material. The reactive inhibitive coating prevents the reaction of compounds with acids(e.g., phosphates) in the exhaust gas, which may form a dense glass layer on the outside of the gas sensor. The reactive inhibitive coating is either an alkaline earth oxide ethoxide, and/or carbonate that is deposited on the gas sensor to a thickness so as to preferably provide an excess of either the alkaline earth material.

摘要： A gas sensor system includes an ammonia-sensing cell for generating a signal upon exposure to an unknown gas comprising ammonia, an A/F cell for generating a signal upon exposure to hydrocarbons in the gas, a heater in thermal communication with the cells and a housing in which the cells and the heater are mounted. The housing permits an unknown gas to flow therethrough for contact with the cells, and there is a sensor control circuit in communication with the cells. The sensor control circuit is configured to utilize the signals from the cells to generate an ammonia concentration signal indicating the concentration of ammonia in the unknown gas. Ammonia may be sensed in an unknown gas by heating such cells to selected working temperatures, exposing them to an unknown gas, obtaining signals from the cells, and using the cell signals to determine the ammonia content.

摘要： Disclosed herein is a gas sensor having a small amount of lead oxide incorporated into an inner electrode and an outer electrode, and a method for depositing the lead oxide. The lead oxide is applied in an amount sufficient to effectuate consistent performance during sensor break-in. Lead oxide is transferred to the electrodes of the sensor element during the fabrication process by exposing the sensor element to glass having a known lead content during a heating step. Lead oxide from the glass is vaporized and deposited on the electrodes in the form of lead oxide. The deposited lead oxide is incorporated into the electrodes of the sensor element. The lead oxide reduces performance irregularities thereby improving performance during the initial use of the gas sensor.
