Vibration-insensitive temperature sensing system based on fluorescence decay and using a digital processing approach
Optional Fields
Digital signal processing Optical fibre sensors Temperature measurements
A fluorescence-based temperature sensor system using a digital signal processing approach has been developed and evaluated in operation on a working automotive engine. The signal processing approach, using the least-squares method, makes the system relatively insensitive to intensity variations in the probe and thus provides more precise measurements when compared to a previous system designed using analogue phase-locked detection. Experiments carried out to determine the emission temperatures of a running car engine have demonstrated the effectiveness of the sensor system in monitoring exhaust temperatures up to 250 C, and potentially higher. 2006 IOP Publishing Ltd.
