    Abstract

    This paper describes the fabrication and testing of Mg-doped SrTiO3 thick-film oxygen sensors with an integrated Pt heater. The results show that the sensor exhibits a P-o2 dependence according to R proportional to p(o2)(-1/4) in the considered P-o2 range(2.5 x 10(-5) bar < P-o2 < 0.21 bar) and a response and recovery time of 1-2 and 50 s, respectively. A temperature of 600 degrees C could be reached by a relative low power consumption of the Pt heater. (C) 2000 Elsevier Science S.A. All rights reserved.
