Abstract
Systems and methods for measuring temperature in a gas turbine are disclosed. The method can include directing a first acoustic signal and a second acoustic signal towards a gas path in a turbine; receiving the first acoustic signal and the second acoustic signal at a downstream gas path location; combining the first acoustic signal and the second acoustic signal to create a combined acoustic signal, wherein the combined acoustic signal forms at least one of either a signal maxima or a signal minima; and based at least in part on the combined acoustic signal, determining a temperature of the gas path.
