Abstract
In a pyrometer system, a pyrometer provides output signals to a processor indicative of the temperature of rotating blades in a gas-turbine engine. The processor includes a synchronization unit and a gate controlled by the synchronization unit. After monitoring the output of the pyrometer to identify which parts of the output signal arise from radiation from the blades and which arise from the combustion chamber, the synchronization unit is set in synchronism with the blade signals and the gate is controlled to pass signals from the blade and to interrupt signals arising from the combustion chamber. The output of the processor is thereby indicative of blade temperature and is insensitive to combustion chamber radiation.
