Abstract :
We report here a langasite SAW device suitable for sensing temperature and oxygen concentration, with applications such as monitoring the exhaust of oxy-fuel combustion systems. In this paper we report on the observed temperature dependence of oxygen sensitivity, explain the mechanism for this behavior, and present a scheme for temperature compensation.
