Abstract
Systems and methods for measuring temperature in a gas turbine are disclosed. The method can include directing a first acoustic signal towards a gas path in a turbine; directing a second acoustic signal towards the gas path in the 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, where a portion of the first acoustic signal cancels out a portion of the second acoustic signal; and determining a temperature of the gas path based at least in part on the combined acoustic signal.
