Abstract
A bifunctional total NOand Osensor assembly with an internal reference for high temperature sensing. Two electrochemical total NO(NO+NO) measuring systems and method were coupled with a metal/metal oxide internal oxygen reference to detect Oand NOsimultaneously in a combustion environment using a single sensor. A Pd/PdO-containing reference chamber was sealed within a stabilized zirconia superstructure by a high pressure/temperature bonding method. An amperometric and potentiometric NOsensor assembly was built on the outside of the Pd/PdO chamber. Pt-loaded zeolite Y was used to obtain total NOcapacity and also to cover the Pt electrodes for detecting oxygen in the presence of NO.
