Abstract

The present invention relates to a combustion temperature sensor, and, more particularly, to a combustion temperature sensor that measures infrared energy emitted at several preselected wavelengths from a flame and/or a flame's hot gas at a turbine inlet location and applies the energy signals to a calculation model to yield temperature.
