Dynamic Calibration of Pressure Sensors

Abstract: This master thesis is a project report of a system identification experiment of pressure sensors in order to characterise their frequency behaviour. The information about the frequency behaviour is for example very useful in the automotive industry, where pressure sensors are used to measure the dynamic pressures in combustion engines. The sensors are identified by means of impulse response analysis using the Ho and Kalman algorithm based on the use of Markov parameters. The sensors presented in the thesis were identified with a certain level of success, and conclusions such as resonant frequencies and bandwidth could be drawn. This master thesis project is performed in collaboration with SP Technical Research Institute of Sweden.
