Abstract
A solid electrolyte dual gas sensor 10 is made, containing a container body of a first solid electrolyte 11, in contact with a monitor electrode 17 exposed to a monitored gas environment 13 containing selected gas components to be measured, and in contact with a reference electrode 15 which is additionally isolated from the monitored gas environment by a second solid electrolyte 16, and optionally 14, where the second solid electrolyte, at the operating temperature of the gas sensor, is effective to dissociate to provide the sole source of self-generated gases at the reference electrode 15, corresponding to the selected gas components to be measured in the monitored gas environment, where, at the operating temperature of the sensor, the first solid electrolyte 11 is effective to conduct oxygen ions, and the second solid electrolyte 16 is effective to conduct ions selected from the group of sodium ions, potassium ions, and their mixtures.
