Paper Abstract

We present design considerations of a diaphragm-type fiber optic combustion pressure sensor employing a low-cost optoelectronic transceiver. The key transceiver element is a tapered optical fiber bundle-based coupler design that relaxes critical alignment requirements, and allows the use of low-cost components. Sensor system evaluation data are presented for high-engine-load and high-combustion-temperature conditions, and for known detection. The test results closely resemble outputs of a heat-sunk flame-shielded, instrumentation-grade piezoelectric reference transducer, and demonstrate better temperature stability.
