N2 - All-oxide NOx sensing elements based on a solid electrolyte are reported. During operation, a DC current or voltage is applied to the element, and the resultant voltage or current is used as a sensing signal. The elements are nearly "total NOx", with responses to NO and NÜ2 of the same algebraic sign and similar magnitude. For example, 77 ppm NO produces a voltage change of-37% and 77 pprny NO2 a change of-40% for a current-biased element at 873 K and 7 vol% O2- The elements display an [O2] sensitivity that is a decreasing function of [NO x and their DC electrical resistance varies exponentially with temperature. These sensing elements could find application in sensors for measuring [NOx at temperatures near 900 K.
