Novel and practical methods of improving reliability of high temperature measurements in harsh environments are discussed. These improvement methods include: mechanical, optical, electrical and software designs. Discussed are mechanical designs for combustion chambers, gas turbines, and especially corrosive environments. Systems are described which use multi-wavelength algorithms for determining the trustworthiness of measurements. These systems use average and difference calculations of the two wavelengths. Also, hybrid optical and thermocouple sensors are presented.
