Abstract

Sensing the pressure of gasses in the exhaust manifold of an internal combustion engine is a challenging application. The exhaust gasses themselves are rapidly changing with temperatures involved that can be in the region of 800°C. This paper presents a Fibre Optic Pressure Sensor (FOPS) system designed specifically for this application. The FOPS system consists of an Extrinsic Fabry Perot Interferometer / Fibre Bragg Grating hybrid sensor, which is able to measure pressure and temperature simultaneously at the point of measurement, and a feedback controlled single wavelength interrogation technique. The combination of both allows the acquisition of fast pressure fluctuations in high temperature environments.
