Influence of Sensor Installation on Performance of Combustion Pressure Sensors
The objective of this paper is to investigate the influence of different sensor installations and sensor positions on the performance of combustion pressure sensors. Key topics to be evaluated and to be presented are: brief introduction about piezoelectric sensor technology; typical sensor installations on large gas engines; physics of acoustic oscillations and sensor mounting temperature; calculated influence of acoustic oscillations and pressure values; measured results from actual installations, and conclusions and recommendations. The paper will provide some very useful information for enhancing data as well as signal quality. Further more, it will give some recommendations for more suitable sensor installation and for generating a larger benefit for engine operators.
