abstract = "Design and operation of sensing elements for the detection of sulfur dioxide (SO2) at high temperature (800-900°C) is described. The sensing elements consisted of three (two oxide and one Pt) electrodes on yttria-stabilized zirconia substrates. To operate the elements a constant current (usually on the order of 0.1 mA) was driven between two of the electrodes and the voltage between one of these electrodes and the third electrode was monitored and used as the sensing signal. In one example, 31 ppm SO2 caused an approximately 40% change in the element output, and 2 ppm of SO2 could be easily detected. The cross-sensitivity to several interferents such as NOx was evaluated and found to be relatively small in comparison to the SO2 response.",
