Abstract
Abstract A device for measuring the temperature of hot gases from a gas turbine burner section having a first duct which introduces the gases to a heat exchanger which cools the gases by means of air circulated from a high-pressure stage of a compressor to a lowpressure stage of the compressor and two spaced temperature probes downstream of the exchanger. A second duct interconnects the first duct portion upstream of the heat exchanger and a first duct portion intermediate the temperature probes. The outlet of the first duct portion, downstream of the second temperature probe, also communicates with the compressor section so as to establish a pressure differential between the inlet and outlet of the device. A mechanical linkage is pivotably secured to the outputs of the two temperature probes and yields a reading that is proportional to the temperature of the hot gases.
